Anatoly Karpov — 12th World Champion · The Positional Boa Constrictor
RUS · 2780 FIDE · 1970–2005 · 12th World Champion (1975–1985)
Known as the 'Boa Constrictor' of chess. Karpov extinguished his opponents' counterplay before it was even born, binding enemy pieces to passive defense on one wing before opening a decisive second front on the other.

What Club Players Should Steal from Karpov
- Supreme prophylaxis: constantly asks 'What does my opponent want to do next?'—and stops it cold.
- Principle of Two Weaknesses: fixes one structural target on the queenside, then stretches defenders with a kingside break.
- Effortless piece harmony: keeps pieces loosely connected so tactical accidents almost never favor his rival.
- When you hold a space advantage, AVOID unnecessary trades—cramped opponents crave piece exchanges.
- Before launching your own plan, spend 15 seconds checking your opponent's best freeing break and nip it in the bud.
- If one weakness is solidly defended, don't bang your head against it—open a second front on the opposite wing.
Karpov perfected the Closed Ruy Lopez and Queen's Gambit as White, while making the Classical Caro-Kann (4...Bf5 / 4...Nd7) and Queen's Indian impregnable fortresses as Black.
