Strategic ideas

Pin the c3-knight to break White's grip on e4 and force a structural concession
Trade the dark-squared bishop for the knight, permanently doubling White's c-pawns
Attack the head of the chain on d4 with …c5 and …Qa5, not the base
Give up the g7-pawn for time and open lines — the g-file becomes Black's highway
Accept an unbalanced, ugly-looking position where concrete calculation beats general principles

Key themes

Dynamic — Both sides wreck their own structures for activity — nothing here is decided by general rules
Counterattack — Black lets White take on the kingside and counts on queenside pressure arriving first
Open Files — The g-file for Black and the b-file for White both open up and both matter

Typical plans

The Winawer is the French at its most uncompromising. Black pins the knight and then trades it off, saddling White with doubled c-pawns and a permanent weakness on that side. In return White gets the bishop pair and a huge space advantage, and often just helps themselves to g7. The Poisoned Pawn line shown here is one of the most analysed sequences in chess: Black is down a pawn with a king stuck in the centre, and it's completely fine. Botvinnik built a world championship career on these positions.

Move by move

e4 — White claims the centre.
e6 — Black plays the French, preparing …d5 to challenge e4 immediately.
d4 — White builds the ideal centre.
d5 — Black strikes at e4, the defining French move.
Nc3 — White defends e4 with the knight, the most testing choice.
Bb4 — Black pins the knight. Now e4 is defended by a piece that can't legally move — this is the Winawer.
e5 — White pushes past, gaining space and closing the centre.
c5 — Black attacks the base of the chain at d4 immediately.
a3 — White asks the bishop to declare itself.
Bxc3+ — Black takes. The bishop is gone forever, but White's queenside structure is wrecked permanently — that's the Winawer bargain.
bxc3 — White recaptures with the pawn, doubling the c-pawns but reinforcing d4.
Ne7 — Black develops the knight to e7 rather than f6, staying out of the e5-pawn's way and heading for f5.
Qg4 — White hits g7. The rook is loose and Black's kingside is undefended.
Qc7 — Black ignores it entirely and develops with pressure on c3 and e5. This is the Poisoned Pawn — one of the most analysed positions in all of chess.
Qxg7 — White takes the pawn.
Rg8 — Black gets the rook out with tempo, and the g-file is now open toward White's king.
Qxh7 — White grabs a second pawn. The material count is getting silly.
cxd4 — Black takes on d4, opening the position while White's queen is off holidaying on the kingside. Black has no pawns left on the kingside, an uncastled king and full compensation — the engines agree, even if it looks absurd.

Where the line leads

White's plans

Take on g7 and h7 — the pawns are real, and Black's compensation has to be proved
Get the king to safety; with an open g-file and Black's queen active, castling short is often out
Defend the doubled c-pawns and d4 — that chain is the price of the bishop pair

Black's plans

Hit d4 with …c5, …Nc6 and …Qc7 — the head of the chain, not the base
Use the open g-file against White's king rather than mourning the g7-pawn
Target the doubled c-pawns in any endgame; they never stop being weak
