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 we can all learn and improve our chess by studying Petrosian's masterpieces. Move by Move provides an ideal platform to study chess. By continually challenging the reader to answer probing questions throughout the book, the Move by Move format greatly encourages the learning and practising of vital skills just as much as the traditional assimilation of knowledge. Carefully selected questions and answers are designed to keep you actively involved and allow you to monitor your progress as you learn. This is an excellent way to improve your chess skills and knowledge. *Learn from the games of a World Champion *Important ideas absorbed by continued practice *Utilizes an ideal approach to chess study
