French Defence
The French Defence is the opening of strategic counterpunchers: Black invites White to build a big centre, then spends the whole game hammering at it. The bad bishop on c8 is a small price for the healthiest structure in chess — Botvinnik, Korchnoi and Morozevich all made it their life's work.
French Defence is one of the most compelling entries in the Encyclopaedia of Chess Openings — and a line that repays every hour you sink into it.
After 7.Be3 the position resolves into a tense centre: the central pawns still face each other, and the timing and manner of the coming exchange shapes the whole middlegame.

Plans & pawn structures
- 1The central tension is the key decision: releasing it too early hands the opponent a free tempo and a target, so keep it until a capture wins a file, a diagonal or a clear structural edge.
- 2Develop with a purpose: connect the pieces to a concrete plan (a break, a target square, an outpost) instead of making automatic moves.
- 3Watch the pawn breaks — both yours and your opponent's. In these structures the player who times the central break better usually wins the game.
Typical middlegame structures
The main line leads to a tense centre: the central pawns still face each other, and the timing and manner of the coming exchange shapes the whole middlegame. No files have opened yet, so this is a manoeuvring struggle: improve your pieces and prepare the pawn break that will open the position on your terms.
Traps & tactical motifs
The Milner-Barry Gambit traps: after 6...Qb6,careless piece play lets Black's ...Qxb2 and ...Bd7 hits win material.
In the Winawer, grabbing on c3 with the wrong move order loses a piece to the ...Qa5 double hits.
How to Play Against the French Defence
- As White, resolve the central tension on your terms: force the exchange that gives you the better structure rather than letting the opponent choose the moment.

These openings arrive at the very same board position by a different move order — a transposition. Knowing them lets you steer between systems and recognise when your opponent has walked into familiar territory.

Solidly intermediate. The main lines require real study, but the payoff is positions you can play for a lifetime. Best investment for Black players around 1400–2000.
