Viktor Korchnoi is a chess legend. In a career which has spanned over 60 years, he won countless grandmaster tournaments, was a four-time Soviet Champion, a multi-time World Championship Candidate, and twice fought for the World Championship in famous battles with his adversary Anatoly Karpov. Throughout his career Korchnoi continually refined his style and he was as comfortable in defence as he was in attack. He was happy to provoke opponents, accept sacrifices, defend precisely and then ruthlessly exploit weaknesses. In this book, former American Open Champion Cyrus Lakdawala studies his favourite Korchnoi games and examines Korchnoi's skills in the key areas of attack and defence, initiative, exploiting imbalances, accumulating advantages and endgame play. He demonstrates clearly how we can all improve by learning from Korchnoi's play.
