Tigran Vartanovich Petrosian was the silent yet potent master of strangulation - he snuffs out his opponent's plans effectively and is a great exponent of the exchange sacrifice in his games. Taking the title from Botvinnik in 1963, who then retired after FIDE announced the end of the rematch, Petrosian defended his title successfully from Boris Spassky in 1966 with creative and enterprising play much in the style of his challenger. It was in 1969 that he finally yielded his title. To learn more about the art of Petrosian's play, members are welcome to join Bradley Loh as he unfolds many of Petrosian's brilliant positional and tactical gems. See you June 23 Friday 8pm at the Level 3 Conference Room at Thomson CC.
