Improve Your Chess Results by Vladimir Zak
This book examines typical mistakes which are made and illustrates them with games from all levels of play. The problems of planning, analysis and dealing with different types of position are dealt with in detail. A further chapter on developing an opening repertoire highlights an area neglected in previous works, while a final section presents the experiences of the author over many years as a chess coach. Vladimir Zak co-authored the King's Gambit with Korchnoi.
