Petrosian plays a kind of chess many players have never met. He spends his moves on your plans rather than his own, removing attacking ideas before they exist and accepting small concessions, including his trademark exchange sacrifices, to keep the position under control.
The experience is quietly unsettling. Nothing dramatic happens, yet one by one your active options stop working, and by the time you notice, the only play left in the position is his.
Regular games against Petrosian raise the quality of your plans. You learn to prepare ideas properly rather than announce them, to value flexibility and to sense danger in your own position earlier. He is one of the hardest opponents in the catalogue to beat, and one of the most instructive to keep facing.
A single game shows part of the personality. Repeated games reveal more: you begin to recognise familiar structures, recurring plans and the kinds of positions this opponent prefers. That is where the collection becomes interesting, because different personalities put different questions to your chess.
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.
