French Defence: French Wing Gambit
The b4 flank strike — rare, practical, and full of quick traps.
Few openings have shaped modern chess as much as French Defence: French Wing Gambit. It has decided world championships, club trophies and late-night blitz games alike.
After 7.Nxd4 the position resolves into a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated, with the d-file half-open for White and the c-file half-open for Black.
The French Wing Gambit is one of the defining branches of the French Defence — the line you reach when both players want the full fight rather than a quiet draw.

Strategic ideas
Ideas for White
Hold the e5 wedge and attack with f4-f5 space gains, while meeting Black's ...c5/...f6 counterstrikes with precise central play.
Ideas for Black
Attack the base of the chain with ...c5 and ...f6, exploit the light squares with ...Qb6/...Qa5 hits, and free the c8-bishop with ...b6/...Ba6 timing.
Plans & pawn structures
- 1White plays down the d-file — with no White pawn there, a rook lift and pawn lever turn this file into direct pressure on d7.
- 2Black's counterplay runs down the c-file: it is half-open for Black, so the rooks swing there to hit c2 while White is busy elsewhere.
- 3The centre is still fluid: decide early whether to lock it with a pawn advance or dissolve it with an exchange, because that choice picks the whole middlegame plan for you.
Typical middlegame structures
The main line leads to a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated. It leaves the d-file half-open for White, the c-file half-open for Black — that is where the rooks belong and where the middlegame is decided. On the pawns, Black holds a kingside pawn majority — the long-term trump to nurse into the endgame.
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 Wing Gambit
- Neutralise the c-file before Black owns it: challenge with your own rook, or close the file with a pawn so the opponent's main artery of play dries up.
- As White, strike at the fluid centre immediately with your own central pawn or piece pressure, before the opponent locks it into a shape that favours them.
