French Defense: Winawer Variation

About this variation

After 3. Nc3 Bb4, Black pins the knight and often gives up the bishop to double White's pawns. It leads to sharp, unbalanced positions.

The Winawer arises after 1. e4 e6 2. d4 d5 3. Nc3 Bb4. The bishop pins the knight on c3 and threatens to win the e4 pawn. White's main answer is 4. e5, locking the center, and after 4...c5 5. a3 Bxc3+ 6. bxc3 the position is one of the most unbalanced in all of opening theory.

The structure explains the plans. White has the bishop pair, doubled c-pawns and a space advantage on the kingside. Black has given up the dark-squared bishop, which leaves the kingside dark squares weak, but in return has pressure against White's queenside pawns and a solid, if cramped, center. White usually plays on the kingside with Qg4, attacking g7, or with a slower plan of Nf3, a4 and Ba3. Black counterattacks with ...Qc7, ...Ne7, ...Nbc6 and pressure on c3 and the c-file.

The Poisoned Pawn line, 6...Ne7 7. Qg4, is the critical test. Black can give up g7 with ...Qc7 and ...cxd4 for counterplay against White's king, or defend with ...Kf8 or ...O-O. These lines are extremely sharp and both sides need precise knowledge. Quieter seventh moves such as 7. Nf3 and 7. h4 lead to positional battles where White aims to use the bishops and Black aims for a good knight against a bad bishop.

The Winawer suits players with Black who want to play for a win against 1. e4 and are comfortable with long-term imbalances. Botvinnik, Korchnoi and Uhlmann all made it part of their repertoire, and it remains the most ambitious way to play the French.

Because the positions are so concrete, the Winawer is best learned through annotated games. Studying how strong players handle the doubled c-pawns, the weak dark squares and the race between attacks teaches far more than memorizing the first fifteen moves of each line.

It is one of the main lines of the French Defense.
