Tigran Petrosian was a World Chess Champion and a true legend of the game. He was nicknamed "Iron Tigran" because of his incredible defensive skills that made him a formidable opponent who was virtually impossible to defeat. Petrosian was the master of restraint, prophylaxis and prevention. He could spot and defuse threats well before they were created, suck the life out an opponent's position and then seize a vice-like grip on the game.In this book, International Master Thomas Engqvist selects and examines his favourite Petrosian games, and shows us how to learn and to improve our chess by studying Petrosian's masterpieces.Move by Move provides an ideal platform to study chess.
