ARM · Iron Tigran · 1949–1984 · 9th World Champion (1963–1969)
Nicknamed 'Iron Tigran' for being virtually impossible to beat. Petrosian smelled danger ten moves before it appeared—and revolutionized chess by sacrificing a rook for a knight or bishop ('the positional exchange sacrifice') simply to establish an unbreakable color-complex blockade.

What Club Players Should Steal from Petrosian
- Positional exchange sacrifices: gives up a rook for a minor piece to own every dark or light square permanently.
- Early danger radar: snuffs out enemy pawn breaks before attacking pieces even cross the fourth rank.
- Coiled-spring counterstrikes: lures impatient attackers forward, then unleashes sudden tactical knockouts like 30. Qh8+!!.
- Stop worshipping the '5-point rook' when open files are closed—a dominant central knight on d6/e4 plus pawns often crushes a passive rook.
- Check king safety BEFORE launching attacks: fixing one small hole around your king prevents 90% of club losses.
- When ahead, frustrate impatient opponents by denying them active breaks until they overextend.
Petrosian loved fianchetto control against the King's Indian as White and resilient counter-fortresses in the French Winawer and Sicilian Kan/Najdorf as Black.
