French Defense: Winawer Variation
Initial Moves: 1.e4 e6 2.d4 d5 3.Nc3 Bb4
Strategic Summary & Main Idea
The Winawer Variation pins the c3 knight on move three and accepts trading the dark-squared bishop for a structure in which White's c-pawn is doubled. It is the most unbalanced line of the French, and the measurement gives White a clear edge: +0.55 after 3...Bb4, +0.62 after 4.e5 c5 5.a3 Bxc3+ and +0.58 in the main position, with 6.bxc3 Ne7. The Poisoned Pawn, the most famous line, keeps the number at +0.69. What the entry records are White's options that do not pay: the gambits with 4.a3 and 4.Bd2 measure 0.00 and −0.14, and 5.Bd2 against ...c5 sits at −0.15.
The pawn structure this opening produces
The Winawer produces the French's most characteristic structure. After 4.e5 c5 5.a3 Bxc3+ 6.bxc3, White has the e5-d4 chain in the centre, a doubled pawn on c3 and c2 and the bishop pair; Black has the e6-d5 chain, the c5 pawn hitting d4 and no dark-squared bishop. The consequences are direct. The dark squares around Black's king have no natural defender, which is why White's queen goes to g4 on move seven, attacking g7. White's queenside is weak and static, which is why Black plays ...Qa5, ...Qc7 and ...b6 with ...Ba6 against it. And the closed centre sets the pace: Black attacks d4 with ...c5 and ...Nbc6, White attacks the kingside with Qg4, h4 and sometimes a4 and Ba3 to trade the bishop left without a partner. In the Poisoned Pawn, Black gives up g7 and h7 for the g-file and the destruction of White's centre with ...cxd4 and ...dxc3, and the structure becomes an open position with Black's king in the centre.
Typical Plans for White
- Push 4.e5 and force the bishop exchange on c3, keeping the bishop pair
- Against ...Ne7, hit g7 with 7.Qg4 and accept the Poisoned Pawn: the line measures +0.69
- Play 7.Nf3 and a4 for positional play, which measures +0.34, instead of the tactics
- Use the c1 bishop on a3 or d2 and the a4 pawn against Black's queenside
- Avoid the gambits with 4.a3 and 4.Bd2: both return equality
Typical Plans for Black
- Take on c3 and attack d4 with ...c5, ...Nbc6 and ...Qa5
- In the Poisoned Pawn, give up g7 and h7 and destroy the centre with ...cxd4 and ...dxc3
- Against 7.Qg4, castle with 7...O-O or put the king on f8 and accept losing castling
- Do not play 7...f5 against 6...Qc7 7.Qg4: the push opens e6 and measures +1.36
- Do not retreat the bishop with 5...Ba5: 6.b4 and 7.Nb5 gain space with tempo, +0.91

Frequently asked questions
Is the Winawer Poisoned Pawn good for Black?
Not by the measurement: after 7.Qg4 Qc7 8.Qxg7 Rg8 9.Qxh7 cxd4 10.Ne2 Nbc6 11.f4 dxc3, the position measures +0.69, above the main position (+0.58). Black destroys White's centre and gains the g-file, but the king stays in the centre. It is a line for maximum imbalance, not for equality.
What is the best defence to 7.Qg4?
By the measurement, 7...Nf5, which measures +0.48 after 8.Bd3 h5 9.Qf4. The knight defends g7 without giving up pawns. Castling with 7...O-O measures +0.67 and the Poisoned Pawn +0.69; the king on f8 with 7...Kf8 measures +0.73.
How can White avoid Winawer theory?
With 7.Nf3 instead of 7.Qg4, which leads to positional play and measures +0.34, or with the 4.exd5 exchange, which measures +0.32. What does not work are the gambits: 4.a3 measures 0.00 and 4.Bd2 −0.14. And 5.Bd2 against ...c5, avoiding the doubled pawns, measures −0.15.
Common Mistakes & Where Most Amateurs Go Wrong
- 01 Pushing 7...f5? against 6...Qc7 7.Qg4. The pawn guards g7 for one move, but opens e6 and the king's diagonal, and 8.Qg3 keeps the pressure with the dark squares undefended: +1.36. The line:
1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Qc7 7.Qg4 f5 8.Qg3+1.36 - 02 Retreating the bishop with 5...Ba5? instead of taking on c3. 6.b4 cxb4 7.Nb5 drives Black's pieces off the queenside with tempo, and the knight threatens d6: +0.91. The line:
1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Ba5 6.b4 cxb4 7.Nb5+0.91 - 03 Moving the king with 10.Kd1? in the Poisoned Pawn instead of 10.Ne2. The king gains no safety and the position, which measured +0.69 in the main line, drops to 0.00 after 10...dxc3. The line:
1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Ne7 7.Qg4 Qc7 8.Qxg7 Rg8 9.Qxh7 cxd4 10.Kd10.00
