French Defence: Winawer Variation
Also known as Winawer
1.e4 e6 2.d4 d5 3.Nc3 Bb4
The Winawer is the sharpest answer to 3.Nc3 in the French. Black pins the knight with 3...Bb4 and usually swaps it off, handing White the bishop pair and doubled c-pawns in return for a damaged white structure and rich dynamic counterplay.

What it does
After 1.e4 e6 2.d4 d5 3.Nc3, Black plays 3...Bb4, pinning the c3-knight to the white king. The main line runs 4.e5 c5 5.a3 Bxc3+ 6.bxc3, where Black exchanges the bishop to wreck White's queenside pawns. White gains the bishop pair, extra central space and attacking chances on the kingside; Black gets a target on c3, pressure against d4, and a clear plan of undermining the centre with ...cxd4 and piece play.
When to use it
Reach for the Winawer when you meet 3.Nc3 and want an unbalanced, double-edged game rather than a quiet one. It suits players who enjoy concrete, theory-heavy positions and are comfortable accepting structural defects in exchange for activity. If you prefer a calmer, more solid French, the alternatives 3...Nf6 (Classical) or 3...dxe4 (Rubinstein) avoid the Winawer's sharpness.
Why it works
The pin on c3 means White cannot easily maintain both the centre and a sound structure. Forcing Bxc3+ leaves White with doubled, often weak c-pawns and an exposed dark-square complex, while Black piles up on d4 with ...cxd4, ...Qc7, ...Nc6 and ...Nf5. The locked e5/d4 chain cuts White's dark-squared bishop out of play for a while, so Black's lasting structural target frequently outweighs the bishop pair White receives.
Key ideas
- Pin and trade: ...Bxc3 doubles White's c-pawns and weakens d4.
- Attack the chain with ...c5 and ...cxd4 to hit the base on d4.
- Pile up on d4: ...Qc7, ...Nc6, ...Nf5 increase the pressure.
- Black's light bishop is the problem piece - aim for ...b6 or ...f6.
- White seeks kingside play with Qg4 hitting g7 and the king.
- Accept the bishop pair given up; the c3 weakness is your trump.
Watch out
The Qg4 line is the key danger: after 6...Ne7 7.Qg4 White hits g7. The critical Poisoned Pawn 7...Qc7 8.Qxg7 Rg8 9.Qxh7 cxd4 grabs pawns but is very sharp; the solid 7...0-0 (Smyslov) sidesteps it yet concedes kingside chances. Either way, time ...cxd4 accurately or White's centre and bishops take over.
