Historical Origins & Pawn-Structure DNA
1561 Spanish Treatise by Bishop Ruy López de Segura · Closed Spanish Tension & Berlin Queenside Majority · José Raúl Capablanca, Bobby Fischer, Anatoly Karpov, Magnus Carlsen
Named after 16th-century Spanish cleric Ruy López de Segura, the Spanish Game became the proving ground of every World Championship match from Steinitz and Lasker through Fischer, Karpov, Kasparov, and Kramnik's famous 2000 Berlin Wall triumph.
Unlike direct attacks on f7, White's b5-bishop pins the defender of e5, forcing Black to concede queenside concessions with ...a6 and ...b5 while White safeguards e4 with Re1, prepares c3–d4, and maneuvers knights via d2–f1 to probe both flanks simultaneously.
白番の戦略ブループリント
- Retreat 4. Ba4 (preserving tension) or play 4. Bxc6 dxc6 (Exchange Variation targeting pawn structure).
- Castle short, support e4 with Re1, and prepare c3 + d4 while routing Nbd2–Nf1–Ng3.
黒番のカウンタープレイとブレイク
- Kick the Bishop with 3...a6 so ...b5 is always available on demand to break the pin.
- Choose between the rock-solid Closed Chigorin/Breyer (...Be7, ...O-O, ...d6) or the Marshall/Open counterattack.
