Iron Tigran. World Champion 1963–1969. The greatest defensive player who ever lived.
Tigran Petrosian was the greatest defensive player in chess history, and possibly the hardest man on earth to beat. Growing up as an orphan in wartime Tbilisi, he developed an instinct for danger that translated into an uncanny ability to sense threats before they materialized. His style was prophylactic: he would prevent the opponent's plans rather than pursue his own. His exchange sacrifices, giving up a rook for a minor piece to destroy pawn structure or eliminate a dangerous bishop, became his trademark. He won the World Championship in 1963 by defeating Botvinnik and held it for six years. Critics called his style boring; admirers recognized its profound depth.
Notable: Lost only 1 game in 129 World Championship games. His 1963 Candidates result was +5 =19 -1, losing just one game in the entire tournament.
