London: B.T. Batsford Ltd, 1980. — 166 p. — ISBN: 0-7134-2331-8.1.d4 Kf6 2.c4 g6 3.Kc3 Cg7 4.e4: Four Pawns, Samisch & Classical.This book constitutes an attempt to combine a work of reference with a textbook. It therefore contains a compilation of the topical variations required for reference by players of various standards, including, we hope, those of high ranking. It also includes explanations of the various continuations, which, it is hoped, will prove useful for players who are merely studying the secrets of opening theory. We attempt throughout the entire book to reveal the sense behind the various moves and maneuvers of both sides, from the point of view of the basic ideas of the King's Indian Defence. Another thing; it occasionally happens that mistakes made at some time by certain theorists are passed on from one book to another. We would like to avoid this, and therefore at times, we have been forced into a dispute with our colleagues. Of course, the conclusions drawn based on analysis and games played cannot be considered definitive once and for all. Time and practice are the best judges. And that which for us is dead can tomorrow be restored to life by some inquisitive idea, and vice versa.The author will therefore be only too glad if the reader should take an interest in this book, and in this highly interesting opening King's Indian Defence, and introduce into its theory new continuations and ideas, of which the author is unaware. Then the aim which we have set ourselves in working on this book will have been achieved.The purely analytical part of the book is preceded by a brief historical review of the King's Indian Defence. In our opinion, this is necessary, since, on the one hand, its study will not take the reader much time or effort, but, on the other hand, it will enable him to gain a better understanding of the ideas of the defense, which have crystallized during the opening's development.
