So you want to actually play the French Winawer, not just admire the fireworks. Good news: the whole opening flows from one bold decision — trading a bishop to wreck White’s pawns — and once that idea clicks, the moves make sense. We’ll walk the main line one move at a time, right up to the critical 7.Qg4 crossroads where the sharpest lines (including the Poisoned Pawn) branch off.
The line we’re learning: 1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Ne7 7.Qg4 This is the Winawer main line — the …Bxc3+ trade and the Qg4 lunge that defines the whole opening.

The French Winawer main line into 7.Qg4 — where the sharpest battle begins.
Move by move
1.e4 e6 2.d4 d5 — the French start
Every Winawer begins as a normal French Defense: 1…e6 opens a diagonal for the f8-bishop, and 2…d5 challenges White’s e4-pawn head-on. So far, this is the same shape as every French line.
3.Nc3 Bb4 — the pin that names the opening
White defends the e4-pawn with 3.Nc3, and now Black declares for the Winawer with 3…Bb4, pinning the knight to the king.
The point of the pin: the c3-knight is the main defender of e4, but pinned pieces make poor defenders. If White ever kicks the bishop and Black takes on c3, the recapture damages White’s structure. That threat hangs over the whole opening.
4.e5 — grab space, lock the center
White’s most testing reply is 4.e5, pushing past and gaining a big central space advantage. The center is now closed, and the d4–e5 pawn chain is set.
4…c5 — strike the base of the chain
The heartbeat of every French: attack the pawn chain at its base. The chain runs d4–e5, so Black hits d4 with 4…c5. This is the same idea as the French Advance, but with the bishop already committed to b4.
5.a3 — put the question to the bishop
White plays 5.a3, attacking the b4-bishop and forcing it to make a decision: retreat, or take the knight. This little pawn move is what triggers the whole Winawer trade.
5…Bxc3+ 6.bxc3 — the defining moment
Black takes: 5…Bxc3+, and White must recapture with the b-pawn, 6.bxc3 (taking with a piece isn’t possible — the bishop is gone and the queen on d1 doesn’t reach c3 cleanly here). This is the heart of the Winawer.
Look at what just happened. Black gave up the dark-squared bishop for a knight — normally a small concession — to inflict doubled c-pawns on White that can never be undoubled. Those pawns, and the c4/c3 squares in front of them, are what Black plays against for the rest of the game. White, meanwhile, has the two bishops, extra space, and open lines (the b-file and the aggressive Qg4 idea). It’s one of the fairest, richest imbalances in chess.
6…Ne7 — develop toward f5 and keep g7 flexible
Black develops the knight to e7 rather than f6 — from e7 it heads for f5 (hitting d4 and the kingside) and it keeps the f6-square free. It also, importantly, doesn’t block the queen’s route to a5 or c7.
7.Qg4 — the critical lunge
Now White plays the move that gives the Winawer its edge-of-your-seat reputation: 7.Qg4, immediately attacking the g7-pawn. Black has to deal with the threat, and how Black deals with it defines the whole game:
- 7…Qc7 — invites the Poisoned Pawn: 8.Qxg7 Rg8 9.Qxh7 cxd4, where White grabs two pawns and Black gets a furious initiative.
- 7…O-O — castles right into it, accepting a weakened kingside for fast development and piece play (Black meets 8.Bd3 with 8…f5).
- 7…Kf8 — the ugly-but-solid move: Black gives up castling to hold g7 and stay structurally sound.
The tabiya — and where it goes from here
That position after 6.bxc3 is the genuine Winawer tabiya — the crossroads thousands of games grow from. The whole story is the race between two plans:
- Black attacks the c-pawns and the queenside with …Qa5, …Qc7, …Nbc6, …c4, and …Ba6 (to trade White’s good bishop).
- White attacks the kingside with Qg4, Bd3, h4–h5, and the e5-clamp, using the bishop pair and the extra space.
Whoever’s attack lands first usually decides the game — which is exactly why the Winawer produces so many decisive, memorable battles. If White skips 7.Qg4 for the calmer 7.Nf3, the game becomes a slower positional fight over those same squares. All of these branches get their own breakdown on the variations page.
The three moves that matter most
If you remember nothing else about the Winawer main line, remember these:
- …Bxc3+ — the whole point. You trade a bishop to hand White doubled c-pawns. Everything else is built on this.
- …c5 — the French break that opens the queenside and gives your pieces targets around White’s damaged pawns.
- …Qa5 / …Qc7 and …c4 — how you actually attack the c-pawns: pin them, pile on them, or freeze them with …c4 and go to work on the queenside.
Get those ideas and the Winawer stops being a memory test and becomes a plan you can trust. Brand new to it? Start gentle with the Winawer for beginners guide.
FAQ
What is the main line of the French Winawer? 1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3, and usually 6…Ne7 7.Qg4. The …Bxc3+ trade (doubling White’s c-pawns) is the defining moment.
Why does Black play 6…Ne7 instead of 6…Nf6? Because f6 would run into the e5-pawn and block the …f6 break, while e7 heads for the strong f5-square and keeps Black’s structure flexible. It also leaves the g7-pawn to be defended in the Qg4 lines.
Do I have to memorize the Poisoned Pawn? Only if you want to play 7…Qc7. You can sidestep it entirely with 7…Kf8 or 7…O-O, or by choosing 6…Qa5 a move earlier. See the variations page for each path.
What if White doesn’t play 4.e5? Then you’re in a Winawer sideline — 4.exd5 (the Exchange), 4.Bd2, or 4.a3. None of them should trouble a prepared Black; the variations page covers them.
