INTRODUCTION.

There have been few occasions in the annals of chess literature when a book on problems has awakened a sufficient immediate interest to call forth a sequel within a year of its publication. The most noteworthy instance was that of Dr. Oscar Blumenthal's Schachminiaturen. published in 1902. Its success was such that in 1903 Dr. Blumenthal issued his Neue Folge, a work fully equal in fascination to its predecessor. It would appear that in Chess the usual case of the novel is reversed, and the sequel forms the best part of the story.
In presenting herewith a sequel to The White Rooks, it may be hoped that this happy phenomenon will again assert itself. In preparing The White Rooks it certainly seemed that the field had been very thoroughly canvassed. All available material had been diligently searched out by my energetic collaborators, and many original positions specially composed to fill the apparent gaps in the system of classification adopted. No sooner was the book brought out, however, than this feeling of comfortable achievement was promptly dispelled. Fresh material began to pour in within four days after Christmas, and the stream is only now beginning to subside. Many published Rook problems, overlooked in the original search, were found ; and a still larger number was specially composed as a result of the study of the book.
In the first volume 273 Rook problems were included, out of over 400 collected. In this sequel 400 more are given, out of a further harvest of 550. At the present moment, not counting end-games nor positions known to be unsound, my collection contains 967. Assuming that nine-tenths of the extant Rook problems have passed under observation, we may estimate the total output roughly at well over the thousand mark.
This is a high figure for problems depending for their strategy on such a slender White army as the King, his Rooks, and, at most, a few Pawns ; and it suggests some reflections on the trend of modern popular composition which may be worth considering.
A good deal of stress has been laid in the last five years on the possibility and advisability of classifying problems according to the major White force employed in them. This is no new concept. It



was first put forth in Max Lange's Handbuch in 1864. It was then taken up by G. Breitenfeld with great energy, and his large MS. collection of 15,000 problems, based on this system, remains as a monument of his labours. All he ever published was the first of a series of articles dealing with the White Queen and one Bishop. (See Dubuque Chess Journal, 1875). In 1906, after'a lapse of thirty years, this cure-all for the difficulties of classification was revived by Dr. E. Palkoska, of Prague. His elaborate experiments, in which I had the privilege of helping, centred also on the Queen and one Bishop, and the results thereof were published in the early part of this year. Certainly, the system could have had no stouter champion; and those who remain unconvinced- of this panacea are not likely to be converted by any later advocates.
To me the system has one great charm : a child can work the preliminary machinery. Given the suitable uniformity of copies of problems, which every system of classification requires, and this purely mechanical form of sorting can be continued very rapidly and thoroughly. Identities of position can be pointed out with unfailing accuracy; and in some eases the development of themes may be partially, although never at all completely, traced. The system has one great drawback: it considers the chess pieces as an end in themselves, not as the means to an end. It makes themes a function of the chess pieces, as the mathematician would express it, instead of making the pieces simply factors of terms in a variable and infinite series. The system was prophetically, condemned by Shakespeare when he asserted that " 'Tis rank idolatry to make the worship greater than the good."
. The details which arise incidentally to the working out of such a system are many, and soon carry it out of the depths of the child whom we pictured as guiding the preliminary steps. Many differences of opinion are possible over these details, without affecting the fundamental nature of the system ; and the criticisms which may have been called forth by such differences of opinion are of no concern to us here.
What does concern us is the main flaw in the system, to which allusion has been made, that it gives the chess pieces precedence over chess themes as guides to classification. There are fifty-four possible combinations of the major White forces. If we have to consult fifty-four volumes to determine accurately the originality of our latest problem, we cannot claim for our system any great advantage.    And such a necessity is not purely theoretical. Two movers having been more thoroughly classified according to themes than longer problems, I made the further experiment of examining those included in the Queen and Bishop collection, and it was no great surprise to find anticipations to a goodly percentage in problems with other .than the stipulated White officers. Many combinations of White men were brought into use ; so that, while it would be an exaggeration to say that all the fifty-four volumes would have been necessary to arrive at a similar result by simply studying the major White force employed, it is no exaggeration to say that no a priori decision as to which of the fifty-four volumes would have been necessary could safely have been made, and it is very doubtful whether as exhaustive an analysis could have been made even in twenty times the time actually used, supposing all fifty-four of the volumes to have been in existence.
The division of problems according to the major White force employed, then, is of use only in the simplest settings of the simplest types of model-mate problems, or of a few not very complex strategical themes. The more limited the .White force, the more limited will be the content of the whole output of problems using that particular force. A book of problems with White Queen and one Bishop is more useful than one of problems with White Queen, one Rook, two Bishops, and one Knight. Such a book as this would almost be absurd, anyway. Most useful of all would be a collection of problems with only the Queen, or one with only the Knights.
Such books would still be subject to the general and fundamental flaw of the system, but they would treat of a limited field, which is already an advantage, and they would give the beginner in solving and in composition the opportunity to study thoroughly the undiluted action of one of the chess pieces, which is a second advantage and a very considerable one.
Two years ago I had expected to issua as a Christmas greeting a volume of considerable importance. Circumstances, which need not be inflicted on the reader, prevented this at the last moment. In looking about for a substitute, the train of reasoning which we have just gone over occurred to me, and the result was a booklet called Knights and Bishops. Its reception was so favourable that the next year The White Rooks was decided on.
These two books have been spoken of by many critics as parts of the system advocated by Dr. Palkoska. This, in fairness to that author, it should be explained, is true only in part. The attempt has not been to classify problems according to the nature and exact number of the major White force. It has simply been to study the nature and possibilities of certain chess pieces.
In Knights and Bishops, the ban on Queens and Rooks prevailed with the Black force as well as with the White. Further, an exact number of White Knights or Bishops was not a requirement for inclusion in the work. And, thirdly, no attempt at classification was made. The problems included were very limited in number, and chosen only for their merit as problems, with a view to showing the possibilities of the two pieces. As was said in the introduction, whoever can master the Knights and Bishops in simple positions can probably do so in much more complex ones.
The origin of The White Rooks was similar, and followed suggestions from a number of recipients of the earlier work. The attempt was to study the possibilities of this one particular piece. Owing to its narrow limitations, and its extreme monotony of movement, the embargo on the  Black force was removed.
To issue a problem book every year is a very easy matter — as long as the quality of the book is of no importance. As soon as one wants to issue a good book, and a thorough book, every year, the task becomes more difficult. Looking back for six years I.have good reason for not being satisfied. I have, however, at least, worked to do better, occasionally under considerable handicaps and against rather unfortunate circumstances. Three years ago I realised the necessity of a really large manuscript collection to make the proper results possible — and my energies have been very largely centred on its preparation, first dealing with two movers, and more recently with longer problems. At the present rate of progress, an accurate book ought to be possible in two or three more years. Meanwhile, my little make^ shifts, like Knights and Bishops, intended only as a friendly greeting to many friends, should not be taken too seriously, nor a theory of my methods of classification, or of my ideals, based on them.
For in my necessity to get out something palatable quickly I resorted to the system of selection by the force used. That my second venture in this line should have been so successful was a surprise to me. It can be explained perhaps by the consideration of the trend of modern problem taste, which I suggested at the beginning of this Introduction.
The trend of modern problem taste has decidedly been of late years towards simplicity — the two mover is preferred to the longer problems in England, and even in other countries its composition has very greatly increased ; the miniature is preferred to the heavyweight; the problem with a single sharp idea has increased in popularity over the complex blend of varied strategy. Simplicity in every form has its merits and its charms, but depth and complexity should not be lost sight of in its pursuit. The reaction towards complexity and variety will undoubtedly occur in due time ; but the triumph of simplicity at the present moment is well illustrated by the welcome given to a little volume like The White Rooks. Fifteen years ago this would assuredly not have been the case.
That I should issue a second volume on the subject would have seemed to me an absurd suggestion a year ago — but the call for it is too great to be resisted. In responding to it a word of protest and of warning must be spoken. In dealing so exhaustively with the White Rooks, we are indeed making an investigation of some value as far as the study of the Rook itself is concerned. But as to problem classification in general, we are simply blowing a pretty soap-bubble—a creation of air. There is hardly a thought expressed in these two Rook volumes, but could be given a more virile and valuable shape by the use of a larger White force. The volumes compare to an ideal problem collection about as closely as a hospital for convalescent consumptives does to the senate chamber of a vigorous nation. Whether the admiration of this extreme tenuity of construction argues a correspondingly anaemic condition among solvers, it would not be very courteous to inquire too closely.
We must keep this condition clearly in mind, and then let us turn about and enjoy our harvest to the full. We will not forget that finer problems exist, but we will get the full savour out of these light-weights. And it is really a pleasure to see the old lumbering Rook, the Elephant of former days, coming into this late popularity. He mimics the agility of the younger pieces, and performs his circus tricks almost as nimbly as the active Knight, long the mainstay of the problematic ring. Occasionally, a slight rheumatic tendency betrays his weakness, but let us be charitable to him. His duty in the field of problems dates back unchanged many centuries, and his rather dull look when we call upon him for too strenuous exertions probably goes back to the old Good Companion, who did not force him to such unseemly capers. His resources, indeed, are something phenomenal.    A year ago it seemed that they were nearly at an end. But to-day we are none too sure that we can more than fathom their simpler expressions. The analysis of his powers since last Christmas has been in the hands of experts, and I must thank all the composers who have helped thereto by original contributions to this second volume, or by new studies published in the magazines during the year.
Too much stress should not be laid on the classification. It is, at best, a simple guide through the widely varying material which I have collected. I have tried to keep somewhat similar proportions between the two volumes, so that the development of the themes treated in the first might be traced by turning to the corresponding pages in the second. To do this accurately would have been impossible. The chapter dealing with the Black Queen has been greatly extended, and that dealing with sacrifices considerably curtailed, while an entirely new chapter on Black Pawn Promotions has been added. Even to preserve proportions at all closely, considerable elasticity has been resorted to, which a careful critic could readily condemn in many points. I trust this will not disturb the reader any more than it has disturbed me.
Whether a third collection of White Rook problems will be called for remains to be seen. I, for one, hope it will not, for the several reasons already given. Nevertheless, further White Rook problems will undoubtedly be composed. The epidemic cannot subside all in a moment: but on the whole the climax of the outbreak appears to have been passed.
It is not necessary to speak of the contents of this collection here in any detail, as the notes to individual positions will bring out their more salient features. On the whole, their merits are on a slightly higher average plane than in the earlier volume, but there are no single examples as brilliant as the best two or three problems in the other book. This is probably because the earlier problems were absolutely spontaneous, which makes for works of genius, while those in this book are more consciously laboured, which makes rather for constructive perfection and finish.
A few flaws in the first collection (Nos. 8, 20C, 23, 69, and 82) were discovered after publication, and these will be found corrected in the notes to Nos. 108, 120, 123, 169, and 182. It is no easy matter to avoid such flaws in any collection—and I fear that in the present volume, where so much of the work is hitherto unpublished, still greater havoc will be wrought by the diligent and analytic reader. Out of the considerably more than six hundred new Rook

MIROSLAV HAVEL published his first work at a time when the Bohemian Problem-school was already in a nourishing stage of its development. The beginnings of that school were small, and date from the sixties of the last century, a period coincident with the first development of the chess club. At that time, in addition to written and lithographed chess periodicals, which did not enjoy a long life, and which have now only an historical interest, the chess column began to appear as a regular newspaper feature. Chief among these early columns may be mentioned: Rodinna Kronika, Kvety, Svetozor, Humoristicke Listy, Palecek and others. They contained for the most part problems and games, with here and there articles on the theory and aesthetics of the problem. It was these articles that laid the foundation of the Bohemian problem school. Chief among the columns of that day was the weekly Svetozor, and it maintained its lead for a long period. On the problem side it exhibited the development as well as the history of the Bohemian problem, and was greatly influenced by the ingenious Dr. J. Dobrusky. It is chiefly due to him that the traditions of the Bohemian school were created and fostered. In the Svetozor the publication of successful problems from local and international tourneys inspired and encouraged both old and new adepts of the art. In 1885 Zlata Praha (Golden Prague) took over the leadership from the Svetozor.
The output of the school grew to such an extent that in 1887 it became possible to publish a first collection of Bohemian problems. The volume contained 321 problems by forty-one composers, and an interesting - introduction by J. Pospisil in the shape of a theoretical study of the Bohemian problem, a study which, in the main, is even to-day quite up-to-date. The following are the composers represented:— Cimburek, Dr. Cernovsky, Dr. Dobrusky, Drtina, Fiala, Freytag, Frohmann, Hanc, Hinkenikl and Kahles, Hochmann, Chmelar, Chocholous, Kober, Kollmann, Kondelik, Konig, Kotrc, Koutnik, Dr. Kvicala, A. and K. Makovsky, Dr. E. Mazel, Moucka, Dr. Musil, Paclt, Pajkr, Pilnacek, J. and K. Pospisil, Racek, Slavik, Schaferling, Svejda, Smutny, Toscani, Traxler, Dr. Tuzar, Valenta, Vetesnik, and Votruba. Thanks to this representative collection, the Bohemian school became popular, and penetrated every frontier of the world of chess. Most of these above-named pioneers have long since died, and the few that remain, with the exception of Chocholous, Kotrc, Traxler and Vetesnik, have left off composing. To the talent of these early pioneers the fame of the Bohemian school is due. Our most distinguished composers in the decade 1887-1897 were Behal, Cumpe, Hostan, Kesl, Kosek, Dr. Klir, Dr. Palkoska, Zimmermann and others. In 1896 the first Bohemian chess monthly was founded, Ceske Listy Sachove, but owing to insufficient support it ceased publication after four years. A similar fate attended Sachove Listy (founded 1900) after three years' existence. Despite great enthusiasm and personal sacrifices both these periodicals succumbed, but in their place several chess columns made their appearance in different papers and did much to popularise chess among the public generally.
In 1905 the various chess clubs united into an association under the name of Ustredni Jednota Ceskoslovenskych Suchistu, and under the auspices of this association the monthly Casopis Ceskych Sacliistu (afterwards changed to Cusopis Ceskoslovenskych Saclustu) was established in 1906. This periodical was founded on so sound a basis that it has been able even to survive, the horrors and tumult of the world war. Although the Bohemian school developed according to principles laid down by generations of national composers, nevertheless at different times a tendency to deviate would manifest itself in the individual genius and character of some gifted composer. Among those composers who have stamped upon the school special characteristics, perhaps the most important is Miroslav Kostal, or, as he is known throughout the chess world, M. Havel.


Miroslav Kostal [Havel] (1881-1958)

Born at Teplitz, Bohemia, on November 7th, 1881, Havel has lived since 1884 in Prague, where he studied at the High Technical School. From 1906 onwards he has been an official of the Austrian State Railways, and since the establishment of the Republic an official of the Czechoslovak Railway- Ministry. He published his first problem on May 1st, 1898. After a relatively short period of probation he began to produce works of great depth and beauty, and with such marks of a rare talent as to give promise of being able to surmount every obstacle and reach the loftiest heights. He was speedily acclaimed as a leader who opened up new ways and pointed to new aims. At this time Bohemia was full of rising talent, as may be judged by the following list : Dr. Mach, Cisar, Skalik, Hlineny, Drnek, Kuneticky, and somewhat later, Knotek, Moravec, Bosch and Matousek. In Moravia: Dr. Prikryl, Trcala, Dittrich, Stritecky, Dedrle, Milica, Volf, Dr. Prochazka and, a little later, Kainer. But Havel's problems were of such high quality that they easily surpassed those of his contemporaries. It was evident that under his influence a new problem-type, easily to be distinguished from the old one, was being created. Havel arouses immediate interest by his choice of themes for his problems. With admirable taste and masterly handling he continually produces new pointed combinations with a surprisingly delicate structure. It is perhaps not by chance that he seems to avoid combinations with White Pawns. With his great experience and skill he is under no necessity of employing means that fail rigorously to comply with the laws of economy. Nevertheless we find him no less a master of construction in problems where the principal part is played by the White Pawn. Havel's strength and greatness are due to his unerring judgment, and to a capacity to select the right material for the right combination. He expresses the chosen theme in just the right form with such subtlety that he fully exhausts the combination in all its phases. Although he imposes on himself as rigorous a discipline of thought as he does on his chess material, he is able to produce a form classical in its beauty, compressed to the utmost, conforming to rule and yet elastic with a display of originality and an absence of restraint which evoke admiration.
This clearness of theme and purity of form, with his finely - conceived ideas polished into veritable gems, are the chief characteristics of Havel's great art. He unhesitatingly renounces cheap theatrical effects, and turns resolutely aside from all combinations of the trick and puzzle order. For instance, the White King plays as a rule an unimportant part in a problem. Even the checking defence is in most cases a pseudo-combination brought in only to avoid perhaps a dual or to ensure correctness, and having no connection at all with the real idea of the problem. It is often quite superfluous, and could be eliminated without any damage to the illustration of the combination. Nevertheless, problem literature furnishes many examples of the principal role being assigned to the activity of the White King. Take for instance the famous "Steinitz Gambit" problem by Loyd. Loyd put the whole effect of the problem into the extraordinary, baffling and theatrical key. But if the solver has the courage to make this Key, the rest of the solution which is based on uncovering the batteries is easy. Now compare with it Havel's exemplary translation into the Bohemian. In No. 30B the active force of the White King on ei is expressed most economically, and Havel, by imparting his strong individuality into the King's attack, is able to grip and extend the interest, of the solver right up to the last move. He analyses the rich possibilities of each theme logically, with a particularly clear perception of its   most complete   expression, and it is only natural that as an outcome of this unity of thought an echo is so often produced. We cannot say that Havel was the inventor of those wonderful echo problems, but whoever studies his collection will be easily convinced that Havel has a predilection for this kind of problem, and that his greatest successes are achieved in this field. From a psychological standpoint it is easy to understand the temptation to dwell on and repeat favourite combinations, like a melody in a different key, which after all constitutes the echo. The subjects of his echoes ajre either whole combinations or mating positions, and these are reproduced in a multiple form, either in a positive or negative way. He does not use easy, symmetrical positions but produces a symmetrical thought in an asymmetrical form. Nor is it always the model-mate which is echoed : he understands also impure but economical mates : his echoes are produced in strict harmony with rigid economy. Nowhere is there a sign of artificiality or laboured construction. The whole structure is invariably beautiful in its simplicity. Owing to this rigorous adherence to economy the Bohemian school eschews sacrificial combinations and thereby abandons those fireworks which are so dear to the beginner, .and which may be regarded as the device of undeveloped art. Sacrifices are in reality a veiled uneconomy, a riddance of superfluous pieces. Therefore we find in Havel's problems very sparing use made of sacrifices, and then only when they form an essential part of the idea. Since June 19th, 1920, Havel has been chess editor of the column in Cas (Time), [At the beginning of 1923 the Cas ceased to appear] which with the Pragcr Presse (edited by Dr. Mach) is the most important Bohemian chess - column. Havel is also a very fine solver. With surprising facility he is able to detect the author's idea, picking out the landmarks of the solution almost at sight. His honour list in International problem tourneys is quite imposing. He has gained 38 prizes, of which 16 were First Prizes, besides 15 honorable mentions. But it would not be doing justice to his art  if only   those   problems which gained success in International Tourneys were to be considered. Many of his problems published in different chess columns take rank easily among his best. Zlata Praha, which for some time published many of his original problems, enjoyed the greatest popularity on that account. Havel, like many other great composers, does not seek fame by adding to the number of his tourney successes. He pursues his art for Art's sake, and often hesitates to send his works before judges who may be suspected of finding merit only in superficial splendour. All outside show is distasteful to him, and his problems for the delicacy of their setting alone will probably never be surpassed. Art is international. In time Havel's classical Bohemianism will become common property. That he gave to the Bohemian school this classical style is a reason which by itself makes his work worthy of being studied and criticised with the great earnestness it deserves.

THE BOHEMIAN THEORY of the CHESS PROBLEM.

In considering, generally, the chess problems produced by the composers of Bohemia, it is worth while to recall the tendency of the Czech towards artistic effort and achievement. Since the revival of the nationalistic movement in Bohemia near the end of the eighteenth century, the Czech people have accomplished work of considerable consequence in literature and the fine arts, and above all in music — in which connection it is of interest to remember the constantly noticed correlation of Music and  Chess. In fact, the Bohemian Chess Problem may be regarded as one of the minor and later artistic products of the Bohemian nationalistic movement, and we find — as we should expect among a people so highly endowed with the instinct and faculties for artistic expression, and moreover so musical — that the chess problem assumes a distinctly aesthetic form. The existence of a School of Art of any sort, implies the existence of principles, both technical and aesthetic. One school learns from another, continued analysis and conflict of ideals leading to reconciliations which involve an advance in theory, and simultaneously with this increase of technical knowledge the basis of a true aesthetic code is laid down. So it has been with the chess problem; for the code to which the best modern composers yield allegiance is not the discovery of any one people or any one age, but has arisen from the endeavours of many composers of many nationalities to endow problem construction with the highest artistic qualities of which it is capable. Though all the fine composers of the last forty years or more, have contrubuted to the formation of our present theory of the problem, it is in the development of its aesthetic side that the influence of the Bohemian school has been paramount. The popularity of their works has involved the spread of their teachings throughout the entire world, and composers of other nationalities have to a remarkable extent been taught and stimulated by their achievements. The Bohemian school may be taken as having originated between the years 1860-70. Anton König is credited by his countrymen with being its founder, and if this be so, then he must take rank with those other great pioneers, Konrad Bayer and Samuel Loyd. König soon found disciples, or associates, in J. Drtina, J. Paclt, A. Kvicala, K. Makovsky. and K. Kober. Between 1870 and 1880 the ranks of the new school were joined by composers of extraordinary talent, most prominent of  whom were Jan Dobrusky and Jiri Chocholous. Dobrusky, certainly the greatest of the earlier Czech composers, did more than any other man of this period to demonstrate the high artistic value of the Bohemian principles, but the marvellous fertility of Chocholous, and his power of composing with equal ingenuity in many different styles, made him the more popular in Europe generally, and in consequence his work was probably the more widely influential. In the eighties other great composers of the school appeared; J. Kotrc, J. Pilnacek, K. Kondelik, E. Mazel, K. Fiala, L. Vetesnik, and pre-eminently Josef Pospisil. Since that time the number of Bohemian chess artists of the first rank has continued to increase, and one has no difficulty in recalling the familiar names; L. Cimburek, V. Cisar, B. Frohmann, O. Grössl (O. Kuneticky), J. Hanc, J. Hlineny, J. Kerles (F. Skalik), J. Kesl, V. Kosek, M. Kostal (M. Havel), Z. Mach, B. Mikyska, K. Musil, E. Palkoska, B. Prikryl, J. Smutny, J. Svejda, K Traxler, St. Trcala, V. Tuzar, St. Zimmermann. During the period of its battle with German, English and American rivals, much attention was drawn to the new school and much interest was aroused in its principles by the tourneys of the Bohemian Chess Club of Prague (Cesky Spolek Sachovni); and in 1887 appeared  "Ceske Ulohy Sachove," a collection of 320 Bohemian chess problems with an introductory essay by Pospisil entitled "The Outlines of the Theory of the Chess Problem." It was a Bohemian manifesto. Meanwhile a somewhat similar movement had taken place in other countries. The great German composers, Klett in the seventies and Berger ("Das Schachproblem und dessen Kunst-gerechte Darstellung") in the eighties, were moving in the same general direction as the Bohemians, though with more definite insistance on strategic values: whilst in England in 1886, the year before the appearance of Pospisil's essay, "The Chess Problem Text Book" was published, containing Dr. C. Planck's well known introduction, which in many ways anticipated the Bohemian writer's "Outlines." It is needless, here, to discuss the distinctive principles of the German, English and American schools of problem composition, which in the period 1870 —1890 were more or less definitely in opposition to the tenets of Bohemia. A passage from Dr. Planck's essay will mark the distinctions sufficiently for our present purpose. "The German", wrote Dr. Planck in 1886, "excels in depth and beauty, the Englishman in constructive skill, and the American in wit and sharpness of idea, and it is altogether impossible to compare the merits of these divergent characteristics. They defy comparison. Each in a limited degree is necessary to the finest pro-blems, but each can be over-done, because, being antagonistic, if any one be too closely followed, it will almost surely be at the sacrifice of another. The German attains marvellous profundity at the sacrifice of accuracy; the Englishman gives up depth and sharpness of idea for perfection in construction; and the American throws away artistic beauty and constructive elegance to obtain pithy ideas and humorous situations." The development of the problem had, in fact, resulted in a critical conflict of tendencies, and the composers of the eighties were fully conscious both of this conflict and of the nature of the previous evolution. "Only a few decades ago", wrote Pospisil in 1887, "the problem art freed itself from these irksome bonds and attained full independence. It was recognised that the ideas of the actual game, however beautiful and interesting they might sometimes be in themselves, were yet unable in the long run to furnish sufficient material for problem composition, and it became evident that the discovery and investigation of interesting combinations, even though such as could never occur in the actual game, offered in themselves no less charm and enjoyment than the mental duel over the chess board. A new era of the problem art dates from this recognition, in which it has flourished magnificently by the complete alteration of its former methods, and has undergone an almost incredible extension.   The problemist no longer composes for the advantage and benefit of the actual player, his chief endeavour is rather to delight the solver with really beautiful, interesting ideas, though only in a refined form."
So, in 1886, Dr. Planck had written: "A careful comparison of problems composed at different periods will show that the Art has. undergone that very process of evolution which is common to nearly all products of the human intellect, namely, a gradual change always tending from simplicity towards complexity, until the straightforward production of the early composer is scarcely to be recognized in its elaborate and variegated garb of today." But the question which now arose, concerned the future. What are the principles which should govern the composer's endeavour "to delight the solver with beautiful ideas in refined form?" We have to consider the exact nature of the answer which the Bohemian composers made to this question. It may be well, first of all, to notice the attitude of the Bohemians on the question of Difficulty in a problem: a feature inseparable from the nature of the chess problem, the existence of which is implied in the very term "problem". Difficulty has no distinctive relation to any school of construction, for the question of its relative importance as a feature in a problem is really the same for composers of every school, since to make Difficulty the main feature of a problem would be to make the problem a mere puzzle, and no school of composers has gone so far. Yet, short of this, it can only be said that while Difficulty is desirable, and to a certain very limited extent essential, neither beauty nor constructive accuracy can profitably be sacrificed to obtain it. "It is evident", wrote Pospisil in his "Outlines", "from the very term "problem", that an important factor of this chess product lies in the difficulty presented by the unravelling of the combinations contained in the given position. The problem is in this respect, a kind of puzzle and the harder its analysis proves, and the obscurer the tracing of its combinations, so much the more perfect is its construction. Nevertheless an importance is often attached to difficulty of solution which it does not deserve." On this subject all serious composers have for a long time been agreed. But it should be noted that a school of composition which insists above all on strategic, or strictly intellectual, values will inevitably, on the average, produce more difficult problems than one which insists rather on values distinctively aesthetic. "Difficulty," says Dr. Planck, "often conflicts with beauty, yet the finest kind of difficulty may arise out of it." The Bohemian composers put the stress on aesthetic as distinguished from purely intellectual values, and in consequence their problems tend to be relatively easy. But this tendency does not result from any theoretic minimizing of the importance of difficulty. The real distinction of the Bohemian composers consists in their having been the first quite definitely to conceive of the chess problem as a work of art governed by aesthetic laws and to find the very essence of its artistic quality in the principle of economy. The following passage from Pospisil's essay of 1887 is of capital importance. "Ideal beauty" he writes, "in the strictest sense of the words, forms the goal of the Bohemian composer, and to attain this ceaseless pains must be taken. This striving manifests itself in the beauty of the true problem, which should comprise not merely a mainplay, but rather a large number of harmonious and completely united variations. The Bohemian School demands, with unbending strictness, attention to all laws of Art and in especial to Chess Aesthetics as regards purity of mate, economy and balance of material, as well as beauty of initial position. It sees beauty in the solution when there is fresh, natural and unconstrained elegance of construction. It by no means under-rates the importance of a profound and solid general plan, nor that of a hidden solution, but when this seems necessary, it subordinates even these features to the first commandment, — that of beauty." The essentials of the problem being thus expressed, one would have expected to find the author boldly denying the necessity for a main-play. And, in fact, in the above passage he does by implication deny that any such necessity exists. Yet elsewhere in the same essay his language is hardly consistent with such a position. He speaks in one place of "the most important part of the problem's content, namely the mainplay." And, again, more emphatically, "There is a peculiar and undoubted charm in the joining of several ideas, among which the main-play should nevertheless stand out." This unexpected emphasis on the "main-play" appears to indicate that Pospisil in 1887 had not quite freed himself from German influences. The real tendency of the school he represented was, nevertheless, to insist on the representation and blending of two or more ideas of roughly equivalent value in every problem. Yet, to judge by his essay, Pospisil hardly seems to have had the idea of the multiple conception. He thought of the problem as originating in a single idea, as taking its first ideal shape in the mind of the composer in a single thematic form and as acquiring variations of value only during the process of construction. The representation of the initial idea is what he calls the main-play. On the other hand, even though in certain passages of his essay Pospisil emphasized the importance of a main-play, he at the same time appears quite conscious of the real nature of Bohemian tendencies in this respect. "It may happen in cases", he writes, "that problems rich in beautiful combinations may be under- rated for the reason that they contain merely variations and no main-play. It is, however, unquestionably due to the Bohemian composers that this kind of problem poetry is gaining more and more ground and importance." And, again: "It can reasonably be prophesied that the problem art of the future will have as its supreme aim the intertwining of beautiful variations, whether they stand on a. par as regards beauty or culminate in the main-play." It is in such passages as these that the real thought of Bohemia on this question is to be found. Indeed, in 1887, "the intertwining of beautiful variations" was already the "supreme aim" of the Bohemian artists. The most distinctive of the more superficial characteristics of the Bohemian School lay in the enormous importance it attached to purity of mate. Pospisil's essay does not clearly distinguish between mates which are merely pure in themselves and mates which are what we call "models", that is both pure and economical. Among the Bohemian composers of the eighties there was perhaps a tendency to prefer merely "pure" mates to mates which were economical but impure. No mention of this, however, appears in the essay of 1887, and it is clear that when the author speaks of pure mates he is, as a rule, thinking of "models." So much in love with purity were the Bohemians that they were prepared to construct problems for the sake of such mates alone. "The idea of a problem," wrote Pospisil in 1887, presents itself sometimes as a single surprise move, sometimes as beautiful, pure mating positions, sometimes even as a fine multi-move single-shoot combination, or it may base itself on the relation ship of the individual moves with the final result." The significant thing, here, is that the author contemplates with apparent satisfaction the problem which has practically no merit apart from its mates, even though elsewhere in the essay he speaks of such productions as "imperfect." In some valuable notes written by Pospisil so recently as 1907, especially for use in the present work, he speaks of such problems with an emphatic disapproval. "The effect of these problems," he writes, "is purely superficial; they are shallow. Such problems often unite well-known and much used themes; their main play is seen to consist in a mere concurrence of pure mating positions. They are easy to solve, not deep of conception and usually have a crowded position, faulty construction (with short or multiple threats), a weak key move, and other defects." "The Bohemian School," he adds, "should not be judged by such productions." This is true: but it is certainly true also that the Bohemian School did actually tend to produce this sort of problem. Despite the obvious danger of attaching the highest kind of importance to pure mates, the Bohemian experts would have no compromise. "The law of purity of mate," declared Pospisil in 1887, "must be absolutely obeyed, if not in every mate, at least in the most important mate of the main-play or of the variations forming exclusively the problem content." This can only mean that, in the case of a problem which consists essentially of blended variations, each of these must end in at least one model mate. It is a high ideal, but a hard law, and its rigidity would not be possible except in a school which placed aesthetic above intellectual values. "The postulate regarding mating purity is not an arbitrary rule, but is rather a simple and natural result of the nature of the problem, which aims at the finest and most economical utilization of position and material." (Pospisil: Outlines.) Dr. Planck had already very clearly pointed out that model mates are, logically, a detail of perfect economy. The conception of "economy" in a chess problem was not developed solely, nor was even first formulated, by the Bohemian composers. Nevertheless the Bohemian School, more than any other, deserves the credit for enforcing the doctrine. The term "Economy" as very commonly used, includes two distinct ideas: that of an ideal unity consisting in the cooperation of every White piece in every phase of a solution, and that of a ratio between amount of force used and amount of work done. If we say that Economy consists solely in this ratio, then the unity of a problem is a separate matter. It is clear, both from the character of their works and from the 1887 essay, that the Bohemians understood Economy as including unity. Economy in Unity was their motto, as it is that of the modern problem. And the Bohemians were idealists. Not only should all the White pieces exert force in all phases of the solution, but it is highly desirable that the White King and such White Pawns as may be on the board should, at least, take an active part at some stage. The sense of a lack of logic in the convenient ruling that White Pawns do not count in economy is strong in the Bohemian composer. A very sparing and scrupulous use of White Pawns is one of the marks which distinguish Bohemian work from that of the modern Austrian or Viennese School. The demands made on the composer in regard to the use of White pieces, the Bohemian theorists were strongly inclined to extend to the Black force also. In his 1887 Essay, Pospisil admits no more than that the rules of economy apply to the Black force "perhaps not so strictly as to the White". And in his "Notes" of 1907 he remarks that: "The Bohemian composer often spends much labour in order to prevent unsoundness only by the use of the absolutely necessary material, for the repeated addition of Black defensive pieces must be forbidden him." Implied, throughout, is the ideal of an absolutely perfect unity, consisting in the co-operation of the whole White and Black force in every stage of a solution. The ideal is all but impossible of attainment except on a small scale. To refuse to be content with anything less than perfect unity would mere pedantry and would result, if it resulted in anything, in a school of miniatures. The Bohemian theorists made no such blunder. They were aware both that the finest conceptions involve a large amount of force, and that economy in itself has nothing to do with the number of pieces on the board. There is nevertheless a tendency towards work on a small scale discernible among the Bohemian artists : a tendency that becomes pronounced in the work of some of the later and most brilliant among them, as "Havel" and Mach. Absolutely perfect economical unity would logically mean that every White piece was equally active at every stage, in the ratio of its power. This is, strictly speaking, impossible: but the Bohemians rightly insist that good economy implies an harmonious balance. "An ugly effect is produced by a piece which displays no activity in the whole course of the solution but does only guard duty. There should therefore, be a certain balance between the passive and active services of the White force. A piece of which only passive use is made in one variation should, play the greater part in another. If a piece has distinguished itself in the course of the solution, one excuses the minor part it may play in the result — the mating position." (Outlines). A minor but significant characteristic of the Bohemian School is the importance attached by it to the initial position. This also, according to Pospisil (1887), should possess artistic qualities: it should present an attractive picture. "The position," he writes, "should be pleasing to the eye. A position can be called beautiful when the board is not overfilled with pieces, when there is no crowding of men in some places in contrast with empty spaces elsewhere. A good impression is always made by the freedom of action of the pieces." He objects to the use of numerous Black pieces, of far advanced White Pawns, of double and triple Pawns, and of opposing Pawns, as ugly. One must not exaggerate the insistence of the Bohemians on this point, but is far more marked among them than in any other school of composers and is another mark of distinction between them and the great composers of Vienna. The question of duals is, from a Bohemian point of view, a detail only. A dual in a variation of artistic value may, of course, be ruinous and must be a serious flaw. But the Bohemian theory implies that there may be in a problem variations of no importance and duals in these are of little nor no account. Moreover, as Pospisil remarks, "the defence cannot be prohibited from making meaningless or even bad moves." What more is there to say ? Every case must be judged on its merits, but no rigid law against duals is possible to a system of composition which basing itself on unity and economy, aims at realizing the beautiful. Economy in unity, balance and harmony, alike in the initial position and in the play, an "intertwining of beautiful variations," these things are the essence of the Bohemian problem as such. Certain weaknesses or shortcomings of the theory remain to be pointed out. In reading Pospisil's essay, or any other exposition of Bohemian principles, one finds oneself semi- consciously translating the word problem into the term "three-mover". And, in practice, it is evident that the attempt to compose two-movers in accordance with Bohemian theory, has a decided tendency to result merely in the composition of highly artistic light-weight problems, the possibilities of which are already well-nigh exhausted. To the construction of the two-mover, Bohemian principles can have only a limited and modified application, unless we are to make of the two-mover a mere occasional artistic trifle. It can hardly be denied that Bohemian insistence on form tends to the destruction of the two-mover. With regard to the four-mover it is arguable that the Bohemian doctrine will apply to it as to the three-mover. It may be doubted, however, whether the greatly increased difficulty of construction involved in a four-mover does not necessitate some modification of the theory. It may fairly be argued that the intellectual value of a four- mover is of more importance than its form and, seeing that the two are here so hard to reconcile, that it is the latter that must be sacrificed. The endeavour after perfect form in four-movers seems likely to involve some sacrifice of intellectuality just where that quality might be most pronounced. Yet on this point one can only speak with diffidence, remembering the work of Dobrusky. The Bohemian theory, as a theory of the three-mover, errs, if at all, in overestimating the value of form. There is apparent a tendency to under-rate the importance of the purely intellectual side of a problem. A finished form, a high degree of unity, a brilliant sacrifice or two, three variations ending in model mates, and the weaker, at all events, of the Bohemian brethren are apt to be satisfied, even if every continuation is a check and the whole process obvious. But the thing is merely pretty. In many, even of the most brilliant, Bohemian problems one feels a lack of subtlety. They are ingenious, they are artistic, they satisfy the Bohemian canons, they are even beautiful: but they lack intellectual distinction. There is of course no necessity that a Bohemian problem should suffer from this lack; and of this fact anyone may quickly convince himself by examining the problems of this present collection, but it remains true that the Bohemian theory does not sufficiently emphasize the importance of intellectuality in problems. It is, essentially, an aesthetic theory of form. It is just this fact that makes it partially inapplicable to two-movers and to four-movers. From this consideration of the Bohemian theory of the chess problem we pass to an examination of the work of perhaps the greatest artist in three-movers the Bohemian School has yet produced: — the work of Josef Pospisil.

THE WORK OF JOSEF POSPISIL

Josef Pospisil was born at Bestvin, Bohemia, in 1861, and attended the secondary schools and the Institute of Technology in Prague. For some years he has been instructor in Natural History at the People's School of Zizkov, a suburb of Prague. He published his first chess problems in the year 1880. Five years later commenced a remarkable series of tournament successes. In three out of four successive tourneys of the German Chess Association (1885—1892) Pospisil took the first prize for three movers. In 1887 appeared the Bohemian collection, Ceske Ulohy Sachove, with his classic introduction. Between 1888 and 1903 he edited the problem departments of various Bohemian papers; among them Svetozor and Zlata Praha. From 1896 to 1902 he was editor of the problem department of Ceske Listy Sachove. The style of a composer is determined partly by the nature of his conceptions and partly by his dominant pre-occupations during the process of construction, which, again, are fixed by his ideal aim or theory of the problem.The Bohemian composer is pre-oecupied with three things mainly. He desires to render two or more variations with a high degree of economical unity, he desires to secure model mates for his principal variations; and he desires to present an attractive initial setting, suggestive of freedom, without over crowding or obviously unnatural arrangements. Certain classes of conceptions refuse to be treated in this manner; or perhaps one should rather say that certain kinds of effects are incompatible with such treatment. The Bohemian artist, as such, must eschew main-plays of very pronounced subtlety, and cannot hope for effects of extreme sharpness or piquancy. If the strategic conception be thin or commonplace the result of the constructive effort,  even if successful, is likely to be one of those problems of which Pospisil speaks as consisting essentially of "a mere concurrence of pure mating positions." He instances in his Notes (1907) one of his own earlier problems(No. 23) as an example of the baser kind of Bohemianism. But the best Bohemian problems tend towards one of two types, though these, of course, shade into each other. Either they are remarkably brilliant, in which case their strategic content is mainly expressed in sacrifices; or they are remarkably subtle, with a subtlety that is not dependent on any one continuation. There is no single, very deeply wrought variation on which the value of the problem mainly depends. There is probably at least one quiet continuation; but the subtlety of the problem consists in the complex conception, in the way in which the variations hang together, rather than in any particular variation. To render such a subtle and complex conception in the Bohemian manner, with high economy and to decorate it with beautiful mates, involves constructive ability of the finest order.
The present collection includes much superb work both of the more brilliant and of the more subtle type. Of the great Bohemian composers of the eighties and early nineties none was the master of Pospisil in the art of combining subtlety and grace in the three-mover. Chocholous was the more fertile and various; Kotrc, perhaps as great an artist, was far less prolific; Dobrusky, unrivalled in the construction of four-movers, was hardly so great in the three-mover. And in „the intertwining of beautiful variations", with a marked quality of subtlety, it cannot be said that any of the later Bohemian composers has surpassed Pospisil. But to institute comparisons among great problem composers, as among great poets, really only serves to accentuate differences of kind. It may certainly be said that Pospisil is Bohemian among Bohemians. No other composer has worked so logically and consistently on the basis of the Bohemian theory, and no other composer illustrates Bohemian principles so clearly and fully.
This last remark implies that the strategic qualities of Pospisil's work are subordinate to its technical and aesthetic qualities. His problems are marked by brilliance and in a higher degree by subtlety; but they are still more strongly characterized by unity and by grace. He is preoccupied with form rather than with ideas. Above all things he is preoccupied with the mate.
A composer so much in love with definitely artistic form and with beauty of mate might be expected to develop a special fondness for the echo. And, in fact, we find that this special fondness is in a high degree characteristic of Pospisil's work. Nearly forty per cent of the accompanying positions exhibit echoed mates, not always perfect, but approximately so. The language here used is a little loose, since no exact and recognized definition of the echo mate exists. By an "echo" mate we mean one which repeats a previous mate of the problem on a new square, the materials used in the two mates being as similar as possible. It may be interesting and instructive to glance at the different forms of mate most used for echoing purposes by this great master of the echo motive. [...] Throughout this essay the direct reference has been almost always to the composer's three-movers though what has been said applies also, in a degree, to the four-movers. But we must not forget to note the fact that Pospisil is one of the greatest masters of the Bohemian two-mover. The Bohemian two-mover is a thing of very limited possibilities, but at its best it is a thing of beauty. Delicate balance, daintiness, beauty of mates and highly finished economical construction, these are its qualities; and when to these is added a certain strategic subtlety or piquancy the thing becomes classic. Several of the problems in this collection belong to this category.
Very beautiful four-move work has been done by Bohemian composers, but few of them have done much in this kind; Dobrusky, Chocholous and Kondelik being, in this respect, marked exceptions. The demand of the Bohemian artists for high finish, formal perfection and an attractive setting, with their dislike of crowding and of a free use of blocking Pawns, appears to produce a certain shrinking from the construction of four-movers, unless on a small scale. The composer who undertakes to construct a four-mover on the grand scale in accordance with Bohemian principles has set himself the most difficult task possible for a maker of chess problems. Pospisil's four-movers are few in number.    It might be argued that his practice goes to prove that the Bohemian ideal of what a problem should be, has reference essentially to the three-mover. But it must be noted that in constructing" four-movers Pospisil has never abandoned Bohemian principles even while compromising under insuperable difficulties. The result is a short series of really fine problems, profoundly Bohemian, possessed of much beauty, evincing the greatest constructive skill and of the highest interest as representing the attempts of such a master to apply to the four-mover the principles of the Bohemian School.
It is hoped that by the means of this introductory essay, students will the more quickly and easily arrive at an understanding and appreciation of the problems collected in this book. But, after all, the gist of the book lies in the problems themselves. They represent the work of a man who is not only one of the greatest of Bohemian composers, but is, as has heen said, a Bohemian among the Bohemians. A study of his work must needs be delightful to every lover of the chess problem. But it may well be instructive also. Here in England, especially, the nature of Bohemian ideals seems still to be very imperfectly apprehended in many quarters. There is still much for us to learn. And, whatever other purpose it may fulfil, this book will serve, at least, to perpetuate the work of one of the greatest masters of the problem art the chess world has ever known.

INTRODUCTION.

In the Introduction to Running the Gauntlet I explained at some length the difference between the chess moves based on the ordinary rules of play, and the moves based on special privileges which form the only exceptions to those general rules. There are only three such privileges : Castling, the double initial move of Pawns and their capture En Passant, and the Promotion of Pawns.
The origin of the Promotion of Pawns is buried beyond recovery in the past. Evidently, since  Pawns  can only march  " breast forward," as Browning would have described  it, something startling must happen  when they reach the opposite edge of the board. Several possibilities. could  be imagined. They might turn around and walk back again. They might be compelled to march on straight off the board, in a novel form of self-annihilation. But this would be a penalty for their prowess, instead of a reward. Their transfiguration is a most ingenious and appropriate solution of the difficulty. We are now so accustomed to the privilege that we give no thought to its origin. Doubtless it was adopted from some simpler form of board-game, some embryo of checkers. In the known history of Chess there are five stages of the promotion privilege.

I. We meet it first in the Arabic manuscripts, as far back as the ninth century. Here the Pawn could only claim  a Queen (Fers).
II. In the old European chess, prior to 1500, the Pawn still could only claim a Fers ; but the newly promoted Fers had the option of a double jump on its first move. The ordinary Fers move, it will be remembered, consisted of a single step diagonally. The double initial privilege of the Fers,in this second period, is supposed to have been the hint which led to the conception of the extended powers of the modern Queen.
III. In  the  new  Italian  chess,  1500-T700, promotion was again limited to the Queen, and there was no initial privilege.
IV. In non-Italian chess, beginning about 1700, a little before Stamina, the Pawn could claim any piece, provided its equivalent had been removed from the board by capture.
V. The last step was the present rule of promotion to any piece, irrespective of previous captures.

Let us consider these five periods more in detail. The first and third are exactly analogous, except for the difference  of motion between the Fers and the Queen. The Pawn was simply exalted to the rank of the most important piece in the game, and that was all there was to the matter. There is no evident reason why a new Fers or a new Queen should have any extra initial move, such as appeared in the second period ; nor why more than one Fers or one Queen on the board at the same time should be illegal ; nor yet why any player in his senses should desire a less important piece, when he could as well have a Fers or a Queen. Such refinements as these certainly never occurred to the Arabs, and they only gradually occurred to the Europeans.
Here is one of the oldest problems in which the Arab promotion is found : No. I.

No. I. Al Adli. c. 850  A.D.

Mate in five.
1. Pg7 + , Kg8; 2. Ph7 + , KxP ; 3. P = F + , RxF ; 4. Af5 + , Kh8;  5.Sf7 mate.


There is a delightful flavour of strategy about it, which a thousand years and more have not entirely dimmed. In solving it we must remember that the Fers (Queen) could only move one square diagonally, and that the Alfil (Bishop) only attacked, and could only move one square diagonally from that on which it stood. Its move was a leap more closely related in kind to that of the Knight than to the motion of the present day Bishop. Were it not for the Pawn at g6 there would be a mate in two by 1. Sf7 +(the Fers at d5 does not pin this Knight, nor could the Alfil at e6 capture it), and 2. Af5 mate. To do away with this Pawn, the Arabian problemist has hit on the clever device of promotion and sacrifice, as shown in his solution.
In our second period, when the Arab game was introduced in Europe, there was added to the privilege of promotion the further privilege of a double initial leap for the new Fers. An example will be found in the curiosity quoted on p. 14 of Running the Gauntlet, where a fuller explanation of the new Fers' powers was given., These powers, though not for the initial move only, were much greater than the regular powers of an Alfil. An Alfil at ai could only move to C3. A new Fers could move to a3, b2, ci, C3 ; but it could only capture on b2. If there was a slight flavour of clearance strategy in No. I, here (No. II.) is a four-move conditional which shows the promotion by Black and which has fine ambush strategy. The Alfil can only move to a3, a7, e3, e7 ; so the solver must have found the task of giving mate with the Alfil very difficult until he hit on the ingenious ambuscade.

No. II. Bonus Socius c.  1266.

Mate in four, with Alfil.

The promoted Fers occurs in many of these old problems, and probably it was used because its initial move was so much more powerful than the move of the ordinary Fers. No. III is an excellent study in the action of the promoted Fers. The position is a unique one in its appearance. The White King is intentionally omitted, being unnecessary to the solution. In some later versions, it is added at bi, "for manners." In the diagram, the Black King can capture the Fers at g8. He is not in check at h8 from the Fers at f8, because a new Fers cannot capture on the extra squares which are allowed it. The solution should be played over several times until it is fully grasped. One or two moves can be transposed, but that does not affect the merit of the solution, nor the position of the mate, which is as extraordinary as the initial position.

It would be amusing to linger on these delightful old- timers, with their Fers and Alfils, but we must pass on to the third period in the development of Promotions, that of the new European chess, with its mad career of Queens and Bishops across the board in a reckless rivalry of the old and powerful Rooks. No. IV will be a sufficient example of this Period. We will be reminded of it when we come to Nos. 4 A—B and 28C later in this book ; for it is modern in theme as well as in the promotion code it follows. Indeed, any problem of this third promotion period is probably quite orthodox today ; but, conversely, the problems of to-day, owing to the minor promotions, would often not have been solvable by the rules of five hundred years ago.

The privilege of minor transfiguration dates from the diffusion of the non-Italian rules in about 1700. Stamina, 1737, the first composer, according to these rules, used the promotion to Knight several times, but never for the first move. Ponziani, 1769, and Lolli use it sparingly, and also never as key.
The fourth and fifth periods of Pawn Promotion now run side by side. Indeed, instead of " periods," I should perhaps say "codes." Some authorities allowed the unrestricted promotion, which constitutes the fifth code, and which is in general vogue to-day. Others restricted promotion to the pieces whose equivalents had already been removed by capture. That is, in the fourth period, any position in any game or problem can be set up from a single box of chess- men. Bither side may have two Bishops on squares of the same colour, but neither side can ever have two Queens or three Bishops at the same time. If a Pawn reaches the seventh row before any officer of its own army is captured, it cannot according to some be promoted at all, or else according to others it can be promoted to a dummy, to remain "latent" until an officer does fall, whereupon the dummy at once starts to life again as a reincarnation of that particular officer.
To our modern taste all this sounds rather absurd. It is likely, however, that when these rules were devised their application to problems was not thought of, and in games the promotion of a Pawn prior to the loss of any officer would be too rare an event to require much practical discussion. The code arrived at was purely academical. It was never seriously analysed until the wider study of problems betrayed its shortcomings.
Even-to-day it still has a handful of adherents. It is recommended in H. F. L. Meyer's Complete Guide to the Game of Chess, 1882, and it is rigorously followed in that veteran expert's excellent column in the Boy's Own Paper. But there is no evidence that it will ever return into general acceptance. It has one great advantage, and one even greater disadvantage.
Its advantage is that it predicates, so far as problems are concerned, one law for the initial position and for the solution as well. A single set of chess men will meet every emergency.
Its disadvantage is that it often produces effects so fantastic that they blind us to the consistency of its principle. We can conceive of a courtesy which would insist on White mating without claiming other pieces than those already captured ; but we cannot conceive of a rule that would prevent our weaker enemy, Black, from claiming any piece he might wish to ask for. The result of all this is that either way there is an inconsistency. But the question of making our choice is simplified by the fact that so great a majority of the experts have accepted the unrestricted promotion code. So universal is its present adoption that some will wonder at my regarding the matter as a question at all. They do not realise how much any code is a mere convention anyway.
Julius Mendheim, who published two problem collections in Berlin, in 1817 and 1832, is among the strictest adherents of the Fourth Period. Such conditions to his problems as " Mate in nine with the Rook's Pawn, which becomes a Bishop, it being unable to make a second Queen," and such lines in the solutions as " 5. P=B, because a Queen is already present," are of unexpected frequency. "We never find in any of his problems a minor promotion to Rook or Bishop for its own sake. It is invariably a case of avoiding a second Queen. As late as 1862 in Germany and 1878 in Italy, the " one set of chess-men " restriction is found in Diagrams V-VI, and possibly later examples exist.

No. V.

No. V. is a most interesting example. Today we would readily solve it by 1. P=Q, Ra1+ ; 2. Qa3, RxQ + ; 3. KxR, P=S+ ; 4. Kb2, Kg4 ; 5. Qe5 ; but this is not permitted, as it involves two White Queens. The proper solution consists in sacrificing the present Queen, so that a new one can be claimed on a more favourable square.
No. VI is less singular in its solution. The noteworthy feature is that White cannot play 1. PxB=Q owing to the Queen already on the Board. The fact that the problem won a first prize is interesting in view of the date. By 1878, indeed, 1. PxB=Q would have been considered a cook in any country but Italy, and we find a Black Rook added at h8 and a White Pawn at a2 when the problem was reproduced in the Schachzeitung in 1879. The additions, it is there explained, have been made to " conform the position to the German Rules."
With Nos. VII-VIII, we can leave the " one set of chessmen " code. No. VIII was composed as a Christmas joke ;

No. VII. L. Sprega.

1.Pd8, QxB; 2. P becomes B and plays Bb6 mate. 1..., Sb5 ; 2. Qd2 mate, for the King cannot capture it, because the Pawn would become a new Queen and the King would have moved into check.


but No. VII was offered in all seriousness. Its date, 1878, is the same as that of No. VI. The solution is given as a matter of course and without explanation : " 1. Pf8 latent.'' The Italian word used is '' sospeso.'' The composer evidently interprets the promotion rule to forbid claiming a second White Bishop on the dark squares ; although such was not the general interpretation. A
nd now let us come to the orthodox privilege of the present day. Why, one wonders, were our modern minor promotions ever thought of ? Why was any change necessary from the code of the Third Period, allowing unlimited promotion to Queen, but to Queen only ? Surely in actual play, minor promotions practically never occur. Yet the laws of Staunton and Hoyle give express permission to promote a Pawn to any of the pieces. I think the rule has been largely a concession to problemists. Stamma saw the problematic possibilities of Knight promotions and used them in his book. The popularity of his problems and end-games was so great that the Knight promotion was generally accepted as valid. When a law was framed to include the promotion to Knight, it had to be worded so as to include the other two minor pieces. But it was nearly a hundred years before these were given much thought. Their only use was by the " one set of chess-men " school, Julius Mendheim and others.
Then came the rush of the problem revival of the 40's. The sudden multiplication of magazines and columns had an effect we could hardly realise. There was an enormous outburst of production, so great that by 1846, when Alexandre compiled his collection, it was thought that every idea had been presented, that his book would remain up-to-date as a work of reference in spite of such problems as might still be produced. But the vanity of human achievement is nowhere more quickly and more thoroughly seen than in Chess. Two-thirds of a century have barely passed, and how many students are living who may be called truly familiar with Alexandre's Beauties of Chess ? A few of us still cherish the tradition that has been handed down of the good Father, with his old black pipe and his kindly face and his mind always abstracted with its undigested burden of chess problems. But such a memory does not bespeak an intimate acquaintance with his book. To most of us the book is an antediluvian Colossus, quite unworthy of attention. In reality it is a wonderful treasure house, the Homeric epic of the problem world. All the great ideas will be found there, in the crude boldness of heroic times. Unfortunately, the mighty pages are " all Greek " to the modern solver. He has not the patience to work through the inaccuracies and the many moves of the old-timers in search of the solid foundation they rest on. Mr, Murray promises us an annotated text one of these days ; it will be of the greatest service when finished.
But if Alexandre's compilation was not final in the sense he had expected, it may be considered as summing up with great completeness the introductory period of problem composition. The date of his book, as I have so often repeated, marks the beginning of the modern problem. The Palamede dates from 1836 ; the Chess Player's Chronicle from 1841 ; the Illustrated London News column from 1842 (not 1846 as stated in Running the Gauntlet) ; the Leipziger Illustrirte Zeitung column from 1843 ; Loveday's Indian problem from 1845 ; the Schachzeitung from 1846. The dissemination of a general interest in problems went on with great rapidity. It was accompanied by a marked increase in the number of composers and by the emancipation of the chess problem from its earlier position as an off-shoot of the game. The chess problem, in the modern interpretation of the word, was fairly launched.
Before Alexandre the appeal of problems was largely to players. (" I have known persons," he says, in the tone of one making a surprising statement, " pass whole nights in the study of a problem, who never had patience to examine in an author one entire game, not even to learn the openings/') Consequently, the rather obvious nature of early problem   strategy was unavoidable. Sacrifices were the great stand-by of composers. So frequently were they used that their presence became eventually the clue to a solution ; hence the reaction of recent times to model mate problems without sacrifices, and still more recently to the German Interceptional School, which has endeavoured to illustrate all the favourite decoys of the 50's without actual sacrifices.
Now the somewhat obvious character of the appeal made to the solver by the presence of a Pawn promotion in any  problem  must  not  be  overlooked. If the average player were asked what problemists mean when they speak of strategy, he would answer : " Oh, any old trick, like sacrificing your Queen or promoting a Pawn to Knight."
I have never heard of a genuine game where victory was won by a promotion to Rook or Bishop. Loyd used to show an ending, where he claimed to have extricated himself from a tight hole in actual play by a Knight promotion, but that is the only instance I can remember. As soon as composers began to invent problems as distinguished from endings in actual play, it was natural that they should turn to promotions, and then to the minor promotions, for inspiration. Nor is it any surprise to find the proportion of promotions, especially to Knight, in the two thousand problems in Alexandre considerably higher than it would be in any similar representative body of problems to-day.
The same obvious characteristics that made promotions so popular in the early days of the modern art of composition have tended likewise to make them popular among novices in composition ever since. Evolution tells us that the early development of the individual repeats the epitomized history of its species. This is only relatively true of the problemist, for the reason that his tastes are generally already moulded by considerable solving before he takes up composition at all. But even so we recognise in the interest beginners in general show in Pawn Promotions precisely the same delighted surprise that Alexandre's composers betray.
The very first problem in the very first chess column ever printed was a promotion three-mover, reproduced from the Stratagems of Montigny : No.IX.

No. IX. Montigny (1802). No. 1, London Lancet, 1823.

Mate in three.
1. Bb6 + ,KxB; 2. P = S + 1...Ka8 ;   2. P=Q mate.


The second problem in the very first chess magazine, the very first chess magazine, Palamede, 1836, was a four-mover by Calvi with a Knight promotion mate.
Then turn to modern times, and you will find one composer after another whose first attempt has also been in this field. The Bettmann Brothers, P. H. Mikkelsen, B. J. Winter-Wood, C. P. Stubbs, J. Paul  Taylor, G.Chocholous, these are only half a dozen of the more prominent names that occur to me in this connection. Two of these first attempts will be found reprinted as Nos. 41D and 31B of this volume. But apart from absolutely first attempts, it can certainly be generalised that the composers who have only dealt superficially with promotions have done so most prominently in the early days of their devotion to the muse Caissa. It is only the few composers who have made a real study of promotions  and  have sounded  their deeper  possibilities,
who have remained faithful to them throughout their careers as composers. The mysteries of Pawn Promotion, indeed, do not He on the surface. The obvious avoidance of stalemate by claiming a White Rook, and the obvious mate by claiming a Knight, are not the only strategy offered by promotions. The subtle foresight that claims a minor officer two moves in advance, the plural combinations of promotions, the ambushes and clearances, the minor promotions by Black, -all these make up a fertile and beautiful field into which not many composers have entered far.
It is a curious fact, if the reader will stop a moment to reflect about it, that each change in the chess rules of motion and in the exceptions thereto, which I have called privileges, should instantly change the possibilities of all problem composition based on the rules changed. The moment the privilege of Pawn Promotion was extended to allow the claiming of minor pieces, there came into being latently all the combinations which are presented in the following pages. Yet how slowly, and with what labour and hesitation, were these combinations evolved and the general scheme that embraced them all gradually perceived !
Is there not a thrill in looking back to the early days ? They are less than threequarters of a century in the past. Many men born before 1840 are still living. Some living composers even touch hands with the pioneers. E. B. Cook, who has contributed an original problem, No. 41 B, for this volume, was the very first to compose examples of consecutive Rook promotion (The White Rooks, No. 4), of consecutive Bishop promotion (No. 47A of this book), and of consecutive threefold promotion (No. 55B), all in 1854-55. He began composition in 1851, within five years after the publication of Alexandre.
And yet to most of us those days seem very far in the past. There was not a single treatise on composition in, existence ; there were few models ; neither the possibilities of composition were known nor its limits. Any fantastic conception of a chess idea might be possible, only there was no guide how to begin. In a word, all was experiment, all was in the future. To-day, so much is known, so much is in the past, that we can hardly venture on composition without fearing some anticipation of our results. Composition should no longer be altogether experimental ; it should be based, at least in part, on a study of what already exists. It is only by an intensive cultivation of every field of composition that the problem art can advance. Without such an intensive concentration, to return for an example to the present book, Pawn promotions would never have revealed such complex positions as Nos. 54 and 84.
The first step in each branch of composition is to work out the classification of what has been done already. This at once guarantees that any composer who carries any part of the structure still further will be doing something new and very probably something worth while. In the case of Pawn promotions it is easy to work out a comprehensive scheme. The reader need only turn to the System of Classification, at the close of this Introduction, to find provision made for all the material now extant. Further subdivision will be necessary in some cases later, as the number of problems involved increases. Especially will this be required in connection with White Knight continuations and mates by promotion and with suimates. But most small collectors need not worry themselves about these shortcomings. A few comments on the Classification may well be made here once for all, and it will also be of interest to give all together a few early promotion problems, dating before 1850.
There are two fundamental principles underlying all promotion strategy. One is the principle of direct attack (for White) and direct defence (for Black). The other is the avoidance of stalemate (for White) and the attempt to produce self-stalemate (for Black). The principle of attack and defence involves only the promotions to Queen and Knight. The principle of stalemate and self-stalemate involves the promotions to Rook and Bishop, and in a few cases to Knight.
The move of the Queen is a combination of the moves of the Rook and the Bishop. There are consequently many cases where, for purposes of attack or defence, a promotion to Rook or to Bishop is as effective as a promotion to Queen. In No. 1, for instance, White can mate by 5 P xS = Q or B. Here the powers of the greater piece coincide with those of the lesser. It is of prime importance for our understanding of the Theory of Pawn Promotion that, in all such cases, we consider the major officer as including the minor officer. This at once takes the Rook and the Bishop out of the field of direct attack, and simplifies our conception of the whole subject. In No. 1, the mate is undeniably a dual ; but the nature of the dual is so slight that no one has ever questioned the problem's right to rank as one of Loyd's foremost masterpieces. Where the dual promotion occurs as a key, for instance in No. 95A, it is more serious perhaps, but certainly not sufficiently so to justify us in rejecting the problem, as we must have done in the case of any other cook. In our notation, then, throughout the book, we will be careful to write P=Q wherever we can, either for White or  Black. Consequently  the  move  P=R  or  P=B  will indicate at once that P=Q would not be an equivalent and that we are no longer concerned with attack or defence based solely on brute force. The distinction is very important. Many editors have not, in the past, been accurate in regard to it. In my search through books and magazines and columns I have had to deplore repeatedly the loose notation used, which has doubtless prevented many solvers and composers from realising the true functions of the minor promotions in problems. It may appear chivalric to print P=B instead of P= Q, as if the player making the promotion disdained the use of his full strength, but chivalry and logic have been at cross purposes before now. If at every opportunity one makes  a minor promotion, there will be no special interest shown when one does it under compulsion or a special strategic object, for nobody will be on the look-out. If one wishes to draw any lively attention to one's self, one must not cry wolf too often.
All promotions to Queen (except perhaps that in No. 24D) and the majority of promotions to Knight involve some aggressive purpose. But this does not mean that every such promotion strictly denotes a promotion theme. Promotions occur literally in thousands of problems, but many depend for all their interest on other features. The two-movers w.here White gives an incidental mate by 2.P=S and the three-movers where Black makes a subordinate defence by 1..., P=Q are innumerable. Very often they should be classified totally without regard to their promotions.
Here are four striking cases, where the promotions are decidedly interesting, and yet not entirely thematic, for similar effects are obtainable without recourse to promotion.
In Kubbel's No. X all we need to do is to lower the position one square diagonally to the  left, as shown in No. XI.,

No. X. K. A. L. Kubbel.
Schachzeitung, 1908.


Mate in two. 1.Qb5, Ke7 ;  2.P=Smate.
No. XI. S. Gold.
Pittsburg Leader, 28 Jan., 1912.


Mate in two. 1. Qa4, Kd6 ; 2. Sf 7 mate

and the White Knight at h8 will exactly fill the role of Kubbel's Pawn. Compare the mates after i..., Ke7 in No. X and i..., Kd6 in No. XI. The coincidence is striking, and No X would be accepted by most judges as a complete anticipation of No. XI, but a collection of promotion problems would never Mate in two. 1. Qa4, Kd6 ; 2. Sf7 matereveal the similarity. In a general collection like my own one would have to look for it under adjacent lateral White Knight batteries. The similar mates after i..., KxP in the two problems would then at once reveal the identity of theme.
In the case of Nos. XII-XII, the outward resemblance is less obvious. Here the example with promotion, No. XIII, Is the later in date. Again we lower the position, this time two squares, vertically. After making the keys the similarity will become apparent. We readily compare the mates in No. XIII (i..., Kc6, Pd5, Pe6) with those in No. XII (i..., KC4, Pd3, Pe4); but one great difference strikes us. No. XII is a waiter ; No. XIII has a threat, 2. P=Smate ! How is this brought about ? Simply by the difference between a real Knight and a promoted Knight. Note that the Bishop's Pawn in the two problems holds a different positional relationship to his two comrades. Play, in No.XII, 1. Bc8, PC5; 2. Sb6mate, and in No. XIII, 1. Ka7, RxB; 2. P = S mate (threat). Compare these mates carefully. Could more different lines of play well lead to more identical results ? The use of the real Knight in No. XII has made the position, almost of itself I imagine, a waiter ; while in No. XIII the use of the promoted Knight has at once introduced a threat.

Mate in two. 1. Bc8, PC5 ;  2. Sb6 mate

G. Heathcote. Hampstead Express, 1905

In Nos. XIVXV, White's second moves lead to identical results. Here the advantage and the priority lie entirely with the promotion version. No. XIV. has a snap and a suggestiveness which make it infinitely more attractive than No. XV. Although No. XIV might well be included also in a general problem collection under White Knight diagonal sacrifices, so as to bring out this particular relation

Mate in three. 1.Sc8, Kb7;   2.Ke7

ship to No. XV, I think that it should also be retained as a thematic specimen of Pawn promotion.
Nos. XVI-XVII illustrate unthematic Black promotion. In No. XVI, 1. Sd5, P X R=Q leads to a situation analogous

No. XVI. J. Möller. Ill. Zeitung, 1902.

Mate in three. 1. Sd5, PxR= Q ; 2. Bd4
No. XVII.
E. J. W. Kubbel. Schachmatnoe Oboz., 1909

Mate in two. 1.  Be4

with that of No. XVII, and 2. Bd4 corresponds precisely to I. Be4 in the latter. The theme of both problems is the focal action of the Black Queen, and the circumstance, in No. XVI, that the Queen is a promoted Pawn is a matter of curiosity rather than of intrinsic importance.
It would be quite easy to increase this series of comparisons indefinitely, but it is more to our purpose to consider where thematic promotions begin rather than where unthematic promotions end.
Certain features of Pawn promotion will be recognised as unique by every solver. For instance, a White Pawn that, in the process of Queening, discovers check or mate, produces an effect unparallelled in ordinary play. For the Queen cannot discover check. Promotion makes it appear that she does so. See No. 5 and note. Again, by promotion, a Pawn battery can give Knight mates on squares no real Knight could ever reach. Examples will be found under Nos. 10-11. All problems where a White Pawn promotes to Queen and to Knight in separate variations, as in No. 13, or to Knight on two squares, as in No. 9C, are likely to be thematic, and should be carefully studied from the promotion standpoint. A few thematic cases also exist, which we must not overlook, where a promoted Queen supports an old Queen, producing novel or bizarre effects. No. 7 is very noteworthy, owing to the singular quartette of Queen sacrifices, and other two Queens ideas follow under Nos. 7A-D. Corresponding to these, are the frequent cases, Nos. 15, 16, 21, etc., where three or more Knights become involved in the solution. These problems cannot be appreciated with one set of chess-men, and adherents to the Fourth Period of promotion cannot but look askance at them. This is unfortunate, but it cannot be helped ;  and if these pages
should come into the hands of any who still hold the Fourth Period conventions we trust they will humour what must seem to them our fondness for puzzles and eccentricities. The ethics of the question have been debated too often to be gone into here. Suffice it to refer to Jaenisch's Universal Code Adopted by the St. Petersburg Chess Club, 1854, and to the criticisms thereon in the European magazines of the next four years. In Black promotions the double claim of Queen and Knight in two variations almost invariably produces a thematic effect, and this is greatly strengthened where the promotions are repeated on a second square, or by a second Black Pawn.
To sum up the whole subject of promotions involving in a thematic way the principle of direct attack and defence, we can say that, for Black as for White, any promotion theme is deserving of the name which uses a promoted Queen or Knight in a manner in which an old Queen or Knight could not be used, or which repeats the promotion two or more times. Promotion problems involving the consideration of stalemate form a class absolutely distinct from the direct attack and defence class. The two classes are as distinct as any two groups in the entire domain of composition. In making a promotion to Rook or Bishop we are invariably availing ourselves of a lesser force than is at our command, for we could in each case claim a Queen. Such a promotion is a passive sacrifice of power. Like every passive sacrifice, it is motived by some impending threat of stalemate. For in Chess every apparently gallant action is forced by stern necessity. There is in Chess no real courtesy, only a polite treachery. Except with the principle of passive sacrifice, promotions to Rook or Bishop have no analogy with any form of problem strategy. Consequently they are always thematic. The effects arrived at often remind us of other classes of problems, as for instance the four-fold Bishop mates in No. 32A. But in every such  case, there is the added piquancy of the

INTRODUCTION

M. John Augustus Miles a fait paraître, en 1888, deux éditions de mats inversés intitulées : Chess Stars-Etoiles Echiquéennes. Depuis ces étoiles ont brillé d'un bel éclat de popularité, mais elles ont été atteintes par une éclipse partielle. Jusqu'à présent, personne ne s'est opposé à cette éclipse, personne ne s'est demandé si elle était éphémère ou permanente et nul n'en a analysé les causes.
On penserait, de prime-abord, que le docteur Tolosa avait raison, lorsqu'en 1892 il dénommait ces mats inverses les fleurs de serre des échecs. Si cela était exact, on comprendrait facilement comment ils ont été amenés rapidement à jouir d'une riche fécondité qui n'a pas duré. C'est le sort qui a frappé bien des genres exotiques de problèmes : les mats réflexes ; les problèmes à un Roi ; les mats aidés, en un mot toutes les créations fantastiques des cerveaux fatigués des mats directs. C'est aussi le sort qui menace les fantaisies futures. Le mat direct seul parait une fleur indigène, capable de survivre à toutes les vicissitudes de saison, de climat, de style et de goût qui tuent si rapidement les produits plus rares des imaginations moins orthodoxes. Est-ce que Tolosa avait raison de classer les mats inverses parmi les créations de serres chaudes? Sont-ils aussi forts que nos fleurs communes? De moins ordinaire existence, ils demandent une éducation spéciale et une connaissance particulière pour être transplantés dans les jardins de nos  propres compositions, comme telle orchidée indigène dont les couleurs brillantes dorment cachées au fond des bois ? C'est une lourde tâche que de trouver la réponse juste à ces questions.
Les mats inverses ont, au moins, des traits communs avec les mats directs quant à leur origine et leur développement. Leur origine est un peu obscure, mais il semble qu'ils dérivent du vieux jeu inverse, de même que les problèmes directs dérivent du jeu ordinaire. Le jeu inverse, à qui perd gagne, est d'une grande antiquité, mais il a toujours été moins usité que le vrai jeu, par conséquent les fins de partie se rapprochant des problèmes se rencontrent en nombre beaucoup plus restreint que pour les problèmes directs.
M. H. J. R. Murray me dit qu'il n'y a aucune trace du mat inverse dans le vieux jeu mahométan. Les manuscrits connus contiennent quelques six cents positions différentes et son absence, d'une quantité aussi considérable, incline à croire à sa non-existence. Dans le vieux jeu européen on le rencontre rarement : parmi les neuf cents problèmes qui nous restent aujourd'hui dans les manuscrits des xiii-xve siècles, il ne se trouve que dix mats inverses. Au xvie siècle, il existe trois mats inverses. (V. N° 1.) Depuis leur nombre s'est accru peu à peu ; dans le Recueil d'Alexandre (1846) résumant tous les problèmes antérieurs, on en trouve environ cent vingt. Ils sont tous du genre « antique ». Dans le procès de modernisation qui survint, le mat inverse suivit le mat direct à une distance considérable.
Tandis que le mat direct s'émancipait bientôt des vieilles positions à jeu long et monotone, arrivant à une mode complexe et de transition qui donna lieu aux positions artistiques de l'école moderne, le mat inverse ne s'est jamais entièrement libéré des anciens modèles. Cependant il se développa jusqu'au style artistique et fini comme le fît le mat direct, mais, néanmoins il a retenu aussi les positions longues et forcées, que l'on nomme de nos jours Challengers.
L'on dirait que toutes les solutions longues et forcées qui se rencontrent dans tous les problèmes d'avant 1850, sont devenues l'apanage des compositeurs de problèmes inverses et même aujourd'hui le problémiste qui trouve quelque idée à longue portée la présente, presque toujours, sous la forme inverse. Cela se voit clairement dans l'ouvrage que M. Williams a justement intitulé : The Modem Chess Problem. Ce livre contient cent problèmes choisis parmi ceux de son auteur : 86 sont des mats directs en deux et trois coups ; les 14 autres sont des inverses, dont 13 de six à onze coups.
Tandis que l'étude du mat direct n'est que l'analyse historique du développement du style moderne artistique, plus ou moins complexe, l'étude du mat inverse se divise en deux parties.: celle des positions complexes, analogues au mat direct moderne, et celle des problèmes à solution longue et forcée-Cette dernière classe a été de beaucoup la plus féconde; elle aussi a eu son développement vers l'art, l'économie, la beauté des mats, l'originalité d'idée, mais sa forme extérieure a bien peu changé, en comparaison de l'autre classe. On trouvera quelques exemples de problèmes forcés dans ce livre, N08 2 à 12, mais je me suis limité presque entièrement au genre complexe, de façon à pouvoir traiter à peu près complètement au moins l'une des deux classes. La vieille forme, comme je viens de le dire, a été bien plus prolixe. Ce sera un travail à faire plus tard, d'essayer d'en coordonner les meilleurs résultats, dans une autre grande collection. La ligne de démarcation, entre les deux classes de problèmes ; le genre forcé et le genre complexe, est souvent difficile à indiquer, comme le sont toutes les lignes exactes dans l'analyse des problèmes. J'ai décidé, arbitrairement, d'exclure toute position qui n'aurait qu'une ligne de jeu et d'accueillir toutes celles en ayant deux ou davantage, mais je me suis  permis quelques exceptions.
Trois éléments entrent dans le développement du style complexe. Le plus rudimentaire est de présenter une idée monotone dans une position qui permet de donner quelque liberté aux Noirs, liberté qui peut changer ou varier le jeu des Blancs sans toucher à l'idée fondamentale, Les N° 13 à 19 en sont des exemples. Aucuns ne sont d'une date très ancienne et, quoiqu'il y en aie de beaucoup plus antiques, la mode des problèmes monotones variés me semble être plutôt un effet que la cause du nouveau développement que nous sommes en train d'indiquer. Car, si nous analysons cette façon de donner de la liberté d'action aux Noirs, nous voyons qu'elle est souvent libérale et qu'il faut du talent au compositeur habitué cependant à contrôler un certain nombre de possibilités.
Une seconde manière de donner de la variété consiste à faire une série d'échecs, permettant cependant plusieurs réponses des Noirs. Malgré la théorie des livres, une série d'échecs est quelquefois artistique, comme au N° 20, où une suite d'échecs croisés forme la base même du problème. (Voir aussi les N° 578, 697.) Les Nos 21 à 36 démontreront comment, dans les problèmes en plusieurs coups, les échecs répétés se fondent peu à peu dans une série de coups tranquilles. L'on remarquera que les dates de ces compositions sont toujours assez modernes; quoique ces problèmes montrent quelque variété et une absence d'échecs, le nombre de coups ne diminue toujours pas. Ces problèmes appartiennent à une classe à mi-chemin entre les longues positions forcées et les versions complexes, en moins de coups. Ils se l'attachent plutôt à ces premières, car le nombre de coups est un élément dont il n'est guère facile de se libérer. La troisième cause qui contribua à la naissance du mat inverse complexe moderne, a été l'étude de la promotion du Pion. En 1849 H. Pollmächer et R. Schurig publièrent un problème incorrect dans lequel un Pion noir devient Dame sans faire mat immédiatement, le N° 37 est leur version rectifiée. En 1859 un problème en 36 coups faisait Dame sur une case contiguë à celle qu'occupait le Roi blanc, mais P fait D donnait le mat. L'année suivante est paru le N° 38, le comte A. Pongracz le résolut et fit remarquer que par un petit changement l'on pouvait supprimer le Pion blanc et économiser un coup ; MM. Bezzel et O. Wülfing firent la même découverte, voir le N°39. Bien qu'un peu incorrects ces problèmes ont une grande importance historique, ils établissent que différentes pièces noires peuvent être employées dans un entourage fixe.
A ce résultat on ajouta, pendant les dix années qui suivirent, l'émulation de plusieurs concours importants, de sorte que l'on voit les éléments complexes se développer d'années en années. Le concours du New-York Clipper, en 1859, a produit un problème tout à fait moderne : N° 163. Dans le concours de Londres, en 1862, soixante-seize problèmes se mirent en ligne, mais un seulement, le N° 41, mérite de retenir l'attention ; c'est un exemple excellent du style complexe aux échecs répétés. Dans les tournois allemands de 1804, 1867, 1869, la proportion des problèmes modernes avança à pas de géants et deux des problèmes de l'envoi primé au concours du Clipper de 1868, N° 51 et 497, sont des œuvres extrêmement difficiles, eu égard à la date de leur composition. En même temps les journaux du continent, notamment la Schachzeitung, organe du club d'échecs de Berlin, mieux connue sous son nom actuel la Deutsche Schachzeitung, réunissait un groupe nombreux de jeunes enthousiastes du mat inverse ; on en trouvera des spécimens aux N° 43, 52, 55 à 57. Le Handbuch der Schachaufgaben de Lange, 1862, et l'Anthologie de Dufresne et Anderssen, 1864, contiennent, parmi deux centaines de mats inverses, seulement quelques positions complexes — les études de promotion de Pion noir, dont je viens de parler, et un ou deux essais de Sam. Loyd, dont le génie devança toujours son temps — lesquels peuvent prétendre à la valeur moderne. Mais vers les premières années après 1870, BlumenthaJ, Nadebaum, Minchwitz, Jensen, Brown, Shinkman, etc., N° 59 à 76, forgeaient déjà la chaîne des problèmes qui devaient relier les principes de la vieille école aux formes progressives de la nouvelle.
Les années 1876-1877 furent très importantes pour le mat inverse. Sur le continent, le grand concours de la Stratégie marquait l'arrivée d'un genre nouveau, en raison de la condition imposée, d'avoir un temps de repos permettant aux Noirs plusieurs réponses, N° 77 à 88. En Amérique avaient lieu les deux premiers concours pour les deux coups inverses. (Voir la Table des positions primées.) On peut donc dire qu'à cette époque, vers 1880, le mat inverse, nouvelle étoile sur le firmament des échecs, se voyait, pour la première fois, distinctement à l'Orient. La réaction du vieux genre long fut bien violente. Loyd, dans son ouvrage Chess Strategy, 1879,  prévoyait, avec moins de clairvoyance qu'à son ordinaire, que le deux coups inverse serait bientôt la limite pour les problèmes acceptables de ce genre. L'éditeur du British Chess Magazine, en 1882, réclamait
vivement l'envoi de problèmes en deux coups. A partir des concours du Croydon Guardian et du English Mechanie, en 1883, le mat inverse en deux coups a fait son apparition en Angleterre et il y a toujours conservé sa plus grande popularité. Sur le continent, les collections de mats inverses d'Antoine Demonchy, 1882, formaient la dernière étape du vieux genre, quoique la nouvelle mode s'y établissait lentement.
Von Gottschall, de 1880 à 1898, fermait les portes de la Deutsche Schachzeitung aux mats inverses. Il n'y eut pas un seul concours ouvert aux mats inverses sur le continent depuis celui de la Stratégie, en 1876-77, jusqu'à ceux du Täglichen Rundschau en 1900 et de la Stratégie en 1900-02. Dans certains lieux où les mats inverses florissaient, c'était plutôt les plantes exotiques de Tolosa que des espèces sérieuses et dignes d'études. Le titre même de la collection de Fischer : Humor im Schach, 1904, le prouve. Ses positions sont généralement des jeux d'esprit, des échos, des groupes de positions se ressemblant en fait ou en idée, depuis des deux jusqu'à des octaves triples. Sans doute il y a beaucoup d'esprit dans de telles conceptions, N° 915 à 921, mais elles ne constituent pas le terrain dans lequel on doit chercher les orchidées indigènes : les plus beaux mats inverses complexes,
Au nord, le mat inverse eut une adolescence plus rationnelle, de Lemke et Wennberg jusqu'aux Jensens, aux Larsens, à Broholm, Lose et Jespersen. En Amérique, le développement du mat inverse est en grande partie l'histoire des problèmes de W. A. Shinkman. Les autres compositeurs qui le suivirent à distance, Wheeler, Teed, Lissner, n'ont jamais essayé de le dépasser sur son propre terrain, qui, comme nous le verrons plus loin, embrasse toutes les formes d'idées les plus distinctement inverses.
Le zénith fut atteint par le mat inverse en Angleterre. Sous la direction de Townsend, Slater, Andrews, Frankenstein et Planck s'éleva une constellation encore plus brillante. Quoi que moins habile comme compositeur, John Augustus Miles, par ses relations comme correspondant, critique, juge dans les concours et amateur, encouragea l'étude des mats inverses plus qu'aucun autre homme. Ses collections, les volumes de Chess Stars, dont j'ai déjà parle, formèrent une série dans-laquelle chaque auteur de mats inverses espérait trouver place. Malheureusement pour la cause du mat inverse, deux éditions seulement furent publiées. M. Miles mourut à Norwich le 23 juillet 1891, à l'Age de 74 ans. Une troisième édition plus développée devait paraître prochainement, mais elle est encore manuscrite. Je dois a l'obligeance de M. John Keeblc, l'exécuteur échiquéen de M. Miles, d'avoir pu copier une cinquantaine de positions destinées au présent travail.
B. G. Laws, l'un des auteurs du Chess Problem Text Book est au premier rang des amateurs anglais; les mats inverses, qu'il a composés de 1884 à 1894, sont très nombreux et de haute valeur. Il est suivi de très près par G. Hume qui est aussi retiré depuis longtemps des rangs actifs; c'est un auteur un peu moins fécond, dont les œuvres sont toujours très belles-Les mats de J. Keeble datent de la même époque mais dépassent la fin du xrxe siècle; le nombre de ses œuvres inédites: a été assez considérable pour faire porter son nom sur la liste des prix de presque tous les concours qui ont eu lieu depuis 1887 jusqu'à nos jours. Les problèmes de G. A. L. Bull sont aussi très remarquables pour leur grand mérite, quoiqu'ils soient peu nombreux. L'œuvre admirable de W. Gleavc et celle de R. G. Thomson sont plus modernes. Enfin, avec A. F. Mackenzie le mat inverse approchait de la perfection que tous les amateurs estiment possible. La mort du grand maître est une perte encore plus grave pour le mat inverse (pie pour le problème direct, car son génie, pour le premier genre, était presque sans rival. Dans ses mains habiles, des problèmes tels que les positions primées par le British Chess Magazine (1901), bien que peu nombreux, auraient vite placé la stratégie inverse a égalité dans l'admiration du public, avec le mat direct plus hardi, mais cela ne devait pas être! L'éclipsé du mat inverse commença à s'assombrir, en Angleterre, à la fin du concours du Hackney Mercury en 1894 et elle n'a fait qu'augmenter depuis. L'école nationale est maintenant éteinte, malgré les efforts de Wright, de Blake, de Westbury et de plusieurs autres.
Sur le continent, de nouveaux champions paraissent s'approcher. L'école bohémienne qui, il y a quelque vingt-cinq ans, fleurit momentanément sous les efforts de Kondelik, de Mikyska et de Chocholous, trouve un écho dans l'œuvre moderne des Autrichiens, notamment chez Feigl et chez. Nemo. H. Rohr, de Breslau, a été, pendant bien des années, un gladiateur isolé. Sur ses épaules et sur celles du vétéran français K. Pradignat repose le championnat de l'Europe occidentale.
Il faudrait voir jusqu'à quel point peuvent s'unir des groupes de compositeurs aux principes tellement éloignés. Si une nouvelle école doit suivre l'éclipse actuelle, elle sera probablement internationale, unissant les principes de toutes les nations. Si elle doit naître, elle sera basée sur les positions qui composent cette collection, apportant aux diverses formes et aux diverses idées, le piquant, le massif, le pur, une forme extérieure raffinée qui donnera au mat inverse les mêmes beautés du XXe siècle que le mat modèle et les théories économiques ont donné aux fleurs les mieux cultivées du mat direct.
En classant les problèmes que contient cet ouvrage, j'ai principalement considéré deux points. En général, les idées échiquéennes, hormis certains tours de force définis, ne peuvent être classées d'une manière scientifique, mais dans les mats inverses la force libre des Noirs qui le plus souvent est assez restreinte et la position des deux Rois sont des éléments si importants qu'ils donnent souvent, à eux seuls, un cachet particulier au problème.
Notre premier chapitre, si nous considérons les N° 1 à 89 comme positions introductoires, comprendra les Nos 90 à 300 et s'occupera exclusivement du jeu d'une pièce noire. Dans les N08 90 à 134, l'idée consiste à attirer la Dame noire, par plusieurs séries d'échecs, d'une position retirée, jusqu'à une case où elle doit donner échec et mat. Dans les No 90 à 95, la Dame est seule sur l'échiquier, mais dans les autres positions elle a plus ou moins de renforts, d'ailleurs très peu actifs. Les problèmes sont rangés suivant le nombre de coups, ainsi que selon le nombre de cases desquelles provient le mat.
Les mats de la Dame sont moins intéressants que ceux des officiers moins forts. La série de la Tour, N° 135 à 158, commence avec cinq problèmes curieux, les N08 135 à 139, dans lesquels un mat se répète jusqu'à cinq fois. Les autres problèmes avec la Tour déploient d'autres mats répétés quelque peu analogues, ou donnés toujours d'un côté, ou bien de deux directions, en écho.
Les mats du Fou, Nos 159 à 192, sont classés selon le nombre de cases sur lesquelles le Fou est forcé de donner le coup de grâce. Ceux-ci montent d'une seule case, N° 159, et jusqu'à quatre dans le remarquable N° 192.
Les mats du Cavalier, Nos 193 à 240, sont assez restreints en nature, mais ils ont un cachet frais et agréable après les mats plus monotones de la Tour et du Fou. Les mats du Cavalier étaient les favoris de l'école bohémienne, et ils forment la base de positions aussi intéressantes que le N° 193. Elles s'adaptent aussi très bien à des problèmes plus longs, tels que les Nos 203 à 209. L'écho est la forme la plus connue des mats du Cavalier, parfois il est volontaire, N° 210, mais plus habituellement il est forcé, N°* 211 à 213. Il s'obtient de différentes manières : directement N° 214 à 229, ou obliquement N° 230 à 240.
Il arrive rarement qu'une pièce blanche forme l'idée d'un mat inverse. Le N° 241 est une exception, un tour de force du genre de la « Rosace ».
Le Pion est souvent employé dans les mats inverses, car il est facile à guider et il se prête bien aux idées légères, N08 242 à 266. Il y a néanmoins peu de virilité dans cette classe de positions.
D'autre part, le Pion est très intéressant à étudier dans ses différentes promotions. Les N°s 267 à 269 montrent les promotions du Pion blanc; les Nos 270 à 300, 676, 714, celles des Pions noirs. Les variantes ordinaires auxquelles donnent lieu les promotions habituelles, N° 270 à 284, sont déjà beaucoup trop usés, mais les autres exemples montrent que de la stratégie moins conventionnelle est également possible, soit en utilisant plus d'un Pion à la fois, soit en cherchant quelque nouvel emploi, tels que les mats découverts par la pièce promue. Le N° 987 et le Frontispice indiquent un autre emploi : celui dans le genre « à prise » auquel nous reviendrons plus tard.

Notre deuxième chapitre, N° 301 à 502, concerne le jeu des deux Rois. Dans les mats directs, le Roi blanc est souvent hors du combat, occupant une position sûre, pendant que ses soldats poursuivent l'ennemi. Il arrive même que le compositeur éprouve de la difficulté à trouver la case désirée et si ce n'était en raison des conventions universelles, il est probable que le Roi blanc serait entièrement omis dans la moitié des problèmes. Cela ne peut que rarement se produire dans une position inverse, car ce sont les échecs livrés à un Roi qui incitent ceux qui doivent mater l'autre. Les Rois sont en contact immédiat, de sorte qu'un problème inverse est bien plus une bataille royale que ne le peut être aucune classe de problème direct, sauf celles des échecs croisés. Les luttes les plus acharnées seront ainsi celles que nous envisageons maintenant, car, outre l'action passive des deux Rois pour attirer le feu de l'ennemi, l'un ou l'autre prend part activement à la direction de leurs forces.
Quand le Roi blanc se meut, c'est habituellement afin de forcer un contre-échec par un échec découvert : directement, N° 301 à 330; ou obliquement, N° 331 à 337. D'autres fois le monarque s'offre plus paisiblement au sacrifice, soit qu'il se livre dans plusieurs directions, selon le jeu des Noirs, soit encore qu'il entreprenne des voyages plus lointains. On trouvera des exemples de chaque genre parmi les N° 338 à 357. Il arrive rarement que tous les coups dans la variante d'un problème complexe soient joués par le Roi lui-même. Dans les deux coups, cela n'est pas très difficile; mais je connais seulement un trois coups et un quatre coups, Nos 338, 336, 343, de ce genre. C'est quelque chose d'utile pour l'étudiant d'approfondir ses recherches. Dans un problème avec une seule ligne de jeu, il lui serait plus facile d'y arriver. L'œuvre de K. Fischer, toujours très hardi dans ses conceptions, est à son apogée dans ses études sur le Roi blanc recevant le mat sur des cases éloignées l'une de l'autre, N° 364 à 367. Le N° 365 est un chef-d'œuvre.
Nous avons déjà vu que le Roi noir pouvait répondre directement aux attaques de son adversaire couronné. Maintenant nous arrivons aux problèmes où l'offensive est prise par le Roi noir, lui-même. Les découvertes obliques sont peut-être la forme qui sert de base aux attaques des Noirs. Nous l'avons rencontrée dans l'antique position de Polerio, N° 1 ; un problème d'ailleurs qui, avec les quelques transformations exigées par les règles du jour, tel que le transfert du Roi blanc à la case 4D, aurait pu être composé par un auteur vivant, tellement son idée est conforme aux thèmes actuels. La même idée trouve sa forme la plus simple dans le N° 368; mais bien des exemples pourraient être ajoutés au choix libéral que j'ai lait des positions les plus complexes, Nos 309 à 426. L'on remarquera les Nos 391 et 392, dans lesquels le R noir découvre mat sur un maximum de six cases. De même les découvertes directes sont de toutes espèces, depuis les versions complexes anglaises, en deux ou trois coups, jusqu'aux piquants stratagèmes de Shinkman et de Rohr, en 4 et 5 coups, Nos 427 à 501.
Les mats découverts ont en effet un tel charme, dans la stratégie inverse, que j'y ai consacré un chapitre, N08 503 à 605.
Le Fou s'emploie tout aussi bien pour les embuscades des officiers et des Pions que pour celles qui visent le Roi. Les Nos 503 à 506 sont des exemples de l'embuscade avec les Cavaliers ; les Nos 508 a 531 du jeu de Fou et Pion. Ensuite vient l'embuscade latéral du Fou, N° 532 à 539, ou avec Pion équivalent, Nos 540 à 563. Les découvertes en passant des N03 551, 561 et 562 sont surtout merveilleuses et surprenantes.
Les échecs doubles, Tour et Fou, se voient dans les Nos 564 à 578, et l'inverse, Fou et Tour, dans les N° 579 a 586. Ces échecs peuvent eux-mêmes être doublés, d'une seule espèce dans une variante, N° 587 et 588, ou des deux espèces dans deux variantes, N° 589 et 590. De la stratégie indienne, encore plus compliquée, se trouve dans les Nos 591 à 595. Le mat double du Cavalier et de la Tour, N° 596 et 597, ressemble aux mats simples du Cavalier, N° 193 à 209; et la doublure de ce mat, N° 598 à 002, doit être comparée avec les Nos 211 a 213.
