TRANSLATOR'S PREFACE
 As the first edition of Edward Laskcr's CHESS STRATEGY was exhausted within a  comparatively short time of its appearance, the author set himself the task of  altering and improving the work to such an extent that it became to all intents  and purposes a new book. I had the privilege of co-operating with him to a  slight degree on that second edition, and was in consequence able to appreciate  the tremendous amount of work he voluntarily took upon himself to do; I say  voluntarily, because his publishers, anxious to supply the strong demand for the  book, wished to reprint it as it stood. 
 A little later I undertook to translate this second edition into English for  Messrs. Bell & Sons. Only a few months had elapsed, the tournaments at  Petrograd, Chester, and Mannheim had taken place, several new discoveries had  been made, and it is the greatest testimony to Edward Lasker's indefatigable  devotion to the Art of Chess that I am able to say that this is not a  translation of the second edition, but of what is practically a new book. It  contains a new preface, a chapter for beginners, a new introduction, new  variations. Furthermore, a large number of new games have taken the place of old  ones. 
 I have no doubt that any chess player who will take the trouble to study  CHESS STRATEGY will spend many a pleasurable hour. Incidentally new vistas will  be opened to him, and his playing strength increased to a surprising degree.  
 The author says in his preface that he appeals to the intelligence and not  the memory of his readers. In my opinion, too, the student should above all try  to improve his judgment of position. 
 Than the playing over of games contested by experts I can hardly imagine a  greater or purer form of enjoyment. Yet I must at the outset sound a note of  warning against its being done superficially, and with a feverish expectation of  something happening. Every move or combination of moves should be carefully  weighed, and the student should draw his own conclusions and compare them with  what actually happens in the game under examination. 
 This applies particularly to some of the critical positions set out in  diagrams in the course of the exposition of the several games. 
 The reader would derive the greatest possible benefit from a prolonged study  of such positions before seeking to know how the games proceed. After having  formed his own opinion about the merits of a particular position, he should  compare the result with the sequel in the game in question, and thus find out  where his judgment has been at fault. 
 The deeper study of the theory of the openings is of course a necessity to  the student who wishes to become an expert, but the development of his judgment  must precede it. To him Griffith & White's admirable book, Modem Chess  Openings, will be a perfect mine of information. There are thousands of  variations, and in most of them the actual game in which they were first tried  by masters is named, thus adding to the interest and value of the work. 
 I must not omit to mention the invaluable help afforded me by my friend Mr.  John Hart, to whom my warmest thanks are due.

AUTHOR'S PREFACE   THE large majority of chess players who would like to improve their game,  have not the necessary opportunity of pitting themselves against players of  master-strength, or at least of obtaining the desired instruction from personal  intercourse with them. It is for such players that the present work is intended.  The books on which the learner has to rely hardly ever serve his purpose, being  mostly little more than a disjointed tabulation of numberless opening  variations, which cannot be understood without preliminary studies, and  consequently only make for confusion. In the end the connection between the  various lines of play may become clear, after the student has made an exhaustive  study of the subject, but very few would have either the time or the inclination  for such prolonged labour. 
 Therefore another shorter and less empirical way must be found in which to  acquire the understanding of sound play. My system of teaching differs from the  usual ones, in that it sets down at the outset definite elementary principles of  chess strategy by which any move can be gauged at its true value, thus enabling  the learner to form his own judgment as to the manoeuvres under consideration.  In my opinion it is absolutely ESSENTIAL to follow such strategical principles,  and I go so far as to assert that such principles are in themselves SUFFICIENT  for the development and conduct of a correct game of chess. 
 Even though instruction in chess is possible on very general lines alone, yet  I think it advisable and indeed necessary to explain the application of such  principles to the various phases of each game of chess. Otherwise the learner  might unduly delay his progress, and lose valuable time in finding out for  himself certain essentials that could more profitably be pointed out to him.  
 With regard to the way in which I have arranged my subject and the form of  its exposition in detail, I have thought out the following plan. 
 After discussing at length the leading principles underlying sound play, I  have first treated of the OPENINGS, in which such principles are of even more  deciding influence than in any other stage of the game, as far as could be done  on broad lines without having to pay attention to middle and end-game  considerations. 
 I proceeded as follows, by taking as my starting-point the "pawn skeleton"  which is formed in the opening, and round which the pieces should group  themselves in logical fashion. As a consequence of the pawns having so little  mobility, this "pawn skeleton" often preserves its shape right into the  end-game. Applying the general strategical principles to the formation of the  pawn skeleton, the learner acquires the understanding of the leading idea  underlying each opening without having to burden his memory. Not only that, he  will also be able to find a correct plan of development when confronted with  unusual forms of opening. 
 The most important result of this system of teaching is that the learner does  not lose his way in a maze of detail, but has in view at the very outset, the  goal which the many possible variations of the openings are intended to reach.  
 Before I could proceed to the discussion of the middle game, I found it  necessary to treat of the principles governing the END- GAME. For in most cases  play in the middle game is influenced by end-game considerations. Here also it  has been my endeavour as far as possible to reduce my subject to such principles  as are generally applicable. 
 Finally, as regards the MIDDLE GAME, to which the whole of Part II is  devoted, I have again made the handling of pawns, the hardest of all problems of  strategy, the starting-point for my deliberations. I have shown at length how  the various plans initiated by the various openings should be developed further.  To ensure a thorough understanding of the middle game, I have given a large  number of games taken from master play, with numerous and extensive notes. Thus  the student has not to rely only on examples taken haphazard from their context,  but he will at the same time see how middle-game positions, which give  opportunities for special forms of attack, are evolved from the opening. 
 It has been my desire to make the subject easily understandable and at the  same time entertaining, and to appeal less to the memory of my readers than to  their common sense and intelligence. I hope in that way not to have strayed too  far from the ideal I had in mind when writing this book, namely, to apply to  chess the only method of teaching which has proved productive in all branches of  science and art, that is, the education of individual thought. 
 If I have succeeded in this, I shall have the satisfaction of having  contributed a little to the furthering, in the wide circles in which it is  played, of the game which undoubtedly makes the strongest appeal to the  intellect.
