Historical Origins & Pawn-Structure DNA
1834 Paris–London Correspondence Match & Nimzowitsch's Blockade School · e4–d5 / d4–e6 Locked Pawn Chain & ...c5 / ...f6 Chain Breaks · Aron Nimzowitsch, Mikhail Botvinnik, Viktor Korchnoi, Wolfgang Uhlmann
Earned its name in 1834 when Parisian masters defeated London via 1...e6; later, Aron Nimzowitsch and Mikhail Botvinnik turned the French pawn chain and Winawer dark-square counterplay into cornerstones of modern positional theory.
Everything in the French revolves around the locked d4–e5 vs d5–e6 chain: White attacks toward the kingside behind the e5 spearhead, while Black systematically undermines the chain's base with ...c5, chips away at its tip with ...f6, and seeks to activate or trade off the hemmed-in c8-bishop.
白番の戦略ブループリント
- Use your e5 space wedge to cramp Black's kingside and prepare a coordinated f4–f5 kingside offensive.
- Reinforce the d4 base of your pawn chain (c3, Nf3, Be3) so Black's ...c5 + ...Qb6 siege never breaks through.
黒番のカウンタープレイとブレイク
- Attack White's pawn chain at its d4 base immediately with ...c5!, ...Nc6, ...Qb6, and ...Nge7–f5.
- Undermine the head of the chain on e5 with a timely ...f6 break once White's pieces overextend.
