The Queen's Indian is one of Black's most dependable and respected defences to the queen's pawn opening. It's an established favorite amongst world-class Grandmasters such as Vladimir Kramnik, Vishy Anand, Michael Adams, and Judit Polgar, not to mention Anatoly Karpov, who has been a loyal Queen's Indian supporter and theory developer for over three decades. Rather than classically occupying the central squares with pawns, Black adopts a hypermodern approach and endeavors to control this key area with pieces. This procedure leads to rich and varied positions that will appeal to players who like complex play. In this easy-to-read guide, Grandmaster and Queen's Indian expert John Emms goes back to basics, studying the essential principles of the Queen's Indian and its numerous variations. Throughout the book there are an abundance of notes, tips, and warnings to guide improving players, while key strategies, ideas, and tactics for both sides are clearly illustrated.
