When Viktor Korchnoi lost by the narrowest of margins to Anatoly Karpov in Baguio City in 1978, many experts thought it would be his last attempt at the World Championship. However, at the age of 50, he again fought his way through several bitter clashed to earn the right to challenge for a crown he has so eagerly sought since defecting from the USSR in 1976. The failure of this attempts to obtain the release of his wife and son would obviously affect his play for this match and yet he has smashed through previous encounters with Petrosian and Poluhayevsky spurred on by this hatred for the soviet regime. Karpov, at 30, becam World Champion when Bobby Fischer refused to defend his title in 1975, and has been one of the most active and successful World Champions ever, winning almost every top level tournament in which he has played. Grandmaster Raymond Keene is uniquely placed to write this gripping account of the "revenge" match in Merano. He was Korchnoi's second at the last World Championship match but his relationship with the challenger soured amid bitter altercations about gurus, and the sinister Soviet parapsychologist Zukhar which caused his subsequent resignation. He now provides the answer to Anti-Chess, Korchnoi's own embittered account of the previous match.
