Though Anatoly Karpov emerges the winner and official challenger to Fischer, it is easy to regard Korchnoi as the hero for his never-say-die spirit. His ability to mount an attack under most any conditions is matched only by Karpov’s coolness and ingeniousness in defense.The fierce effort Korchnoi displayed is beautifully expressed in the following description of him by a spectator:“The hands feverishly grabbed the head, the burning gaze was wandering over the board, the legs crossed, the body bent in some kind of inexpressible suffering of creative effort.”The book itself begins with succinct and at times fascinating descriptions of the players, their style and history. It presents the games at a level which is more readable and relevant than most comparative efforts. The reader is spared the usual labyrinths of variations. But the excitement of the match and the valor of the players is skillfully conveyed, along with many technical points about grandmaster chess.An added bonus for many though a nuisance to some is the rendering of all games in algebraic notation, rather thjm the descriptive notation usually used in the U.S. The terse but very good explication of the algebraic system given in a one page frontispiece should quickly dispel all mvsteries of that system forthe reader who wishes to make a modest effort.For those who would like alast look at Korchnoi for the nonce (Karpov will soon play Fischer, we hope), here is a characteristic performance by the Leningrad grandmaster. Played in 196 7, this game was presented by the authors to illustrate his style.In our first position Korchnoi, black, has just made an astounding move!BLACKKORCHNOIdO NO 80 O8X NX dXQR QN QB QKB KN KRSUETINWHITE.. .P-KR 4, acrazy movelHe has played the unexpected 20 . .

But in the words of the authors, “the psychological impactof the sudden transformation of a defensive posture into an aggressive one must have been immense.”The following moves then occurred 21.
