French Defense

1.e4 e6

The French Defense starts 1.e4 e6, and after 2.d4 Black plays 2...d5. Black challenges e4 at once with a pawn that is already supported by e6. White has to decide: defend e4 (3.Nc3 or 3.Nd2), push past it (3.e5), or exchange (3.exd5).

The price of the solid structure is the light-squared bishop on c8, which is shut in by the e6 pawn. Much of French strategy revolves around that bishop: trading it with ...b6 and ...Ba6, bringing it out after ...f6 or ...e5, or accepting it as a defender of the pawn chain.

In return Black gets clear plans. When White plays e5, Black attacks the base of White's pawn chain with ...c5 and the head of it with ...f6.

Who should play it

Black gets a solid position with clear targets: White's pawn chain on d4 and e5. The plans are the same in most variations, so understanding beats memorising.

French Defense main line, move by move

1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 5.Nf3 Qb6 6.a3 c4

  1. 1.e4Controls d5 and f5.
  2. 1...e6Prepares ...d5 with a pawn ready to support it.
  3. 2.d4White takes the second central square while Black allows it.
  4. 2...d5Black hits e4 with a supported pawn. White must defend, exchange or advance.
  5. 3.e5White gains space and cramps Black's kingside: the g8 knight can no longer go to f6.
  6. 3...c5Black attacks d4, the base of White's pawn chain. This is the standard reply.
  7. 4.c3Keeps the chain intact, so that ...cxd4 can be met by cxd4.
  8. 4...Nc6Adds a second attacker to d4.
  9. 5.Nf3Develops and defends d4 again.
  10. 5...Qb6The queen attacks d4 and b2. It also makes Bd3 awkward, because the bishop would block the queen's defence of d4 (see the trap below).
  11. 6.a3The main line. White plans b4, gaining queenside space, and takes b4 away from Black's knight and bishop.
  12. 6...c4Black closes the queenside and takes the b3 square. If White now plays b4, Black can capture en passant with ...cxb3.

Key ideas in the French Defense

Plans for White

  • Keep the pawn chain on d4 and e5 and use the space it gives on the kingside.
  • Attack on the kingside with Bd3, Qg4 or a later f4-f5 in some lines.
  • Keep the position closed so Black's light-squared bishop stays passive.
  • Meet ...f6 calmly: often the best answer is to keep e5 supported rather than exchange.

Plans for Black

  • Hit the base of the chain with ...c5 and pile up on d4 with ...Nc6, ...Qb6 and ...Nge7-f5.
  • Attack the head of the chain with ...f6 once the pieces are ready.
  • Solve the c8 bishop problem: trade it with ...b6 and ...Ba6, or route it via d7.
  • Consider queenside castling in some lines, since the kingside is often where White attacks.

Typical plans and pawn structures

The Advance and Steinitz lines create the classic French chain: White pawns on d4 and e5, Black pawns on e6 and d5. White's chain points at the kingside, so White attacks there. Black's chain points at the queenside, so Black attacks there with ...c5, ...Qb6 and sometimes ...b5-b4.

The guiding rule, set out by Aron Nimzowitsch, is to attack a pawn chain at its base. For Black that means d4, which is why ...c5 appears in almost every line. The secondary target is the head of the chain, e5, attacked with ...f6.

In the Winawer (3.Nc3 Bb4) Black often gives up the dark-squared bishop for the c3 knight. White gets doubled c-pawns and the bishop pair; Black gets a solid position and long-term targets on the queenside.

Main variations of the French Defense

Winawer Variation (3.Nc3 Bb4)

1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Ne7 7.Qg4

Black pins the c3 knight and, after 4.e5 c5 5.a3 Bxc3+ 6.bxc3, gives up the bishop pair to double White's pawns. 7.Qg4 attacks g7 at once. The Winawer is the sharpest and most ambitious French.

Classical Steinitz (4.e5)

1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.e5 Nfd7 5.f4 c5 6.Nf3 Nc6 7.Be3

4.e5 drives the knight to d7 and White supports the chain with f4. Black attacks d4 with ...c5 and ...Nc6 while White prepares a kingside push. 4.Bg5 instead leads to the Classical main line, the MacCutcheon (4...Bb4) or the Burn Variation (4...dxe4).

Tarrasch Variation (3.Nd2)

1.e4 e6 2.d4 d5 3.Nd2 Nf6 4.e5 Nfd7 5.Bd3 c5 6.c3 Nc6 7.Ne2

The knight goes to d2, where it cannot be pinned by ...Bb4, and the c-pawn stays free to support d4 with c3. Against 3...Nf6 4.e5 Nfd7 White builds a chain like the Advance, with the bishop on d3 and the knight on e2. 3...c5 is Black's other main reply.

Exchange Variation (3.exd5)

1.e4 e6 2.d4 d5 3.exd5 exd5

Symmetrical and quiet. Black's c8 bishop is free again, which removes the main French problem, so it holds no danger for Black. It is a way for White to avoid theory, but it rarely gives an advantage.

French Defense traps to know

Final position

The Bb5+ queen trap (Advance Variation)

1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 5.Nf3 Qb6 6.Bd3 cxd4 7.cxd4 Nxd4 8.Nxd4 Qxd4 9.Bb5+

With 6.Bd3 the bishop blocks the d-file, so White's queen no longer defends d4. It looks as if Black wins a pawn with 6...cxd4 7.cxd4 Nxd4?, but after 8.Nxd4 Qxd4 9.Bb5+ the bishop gets out of the way with check and the queen on d1 takes the queen on d4 next move. Black should play 7...Bd7; White's 6.Bd3 then becomes the Milner-Barry Gambit, in which White gives up d4 later for development.

Famous players and games

The name comes from an 1834 correspondence match between London and Paris, in which the Paris players adopted 1...e6.

Mikhail Botvinnik and Viktor Korchnoi both used the French in world championship matches, and Wolfgang Uhlmann played almost nothing else with Black. Aron Nimzowitsch, whose pawn-chain theory explains most French plans, was a strong advocate of 3.e5 for White.

French Defense FAQ

Is the French Defense good for beginners?

Yes, for players who like solid positions. The plans repeat across variations (attack d4 with ...c5, then e5 with ...f6), so you can play it well with modest theory. The main thing to learn is how to handle the c8 bishop.

What is the bad bishop in the French Defense?

It is Black's light-squared bishop on c8. With pawns on e6 and d5 on light squares, the bishop has few active diagonals. Black often trades it with ...b6 and ...Ba6 or reroutes it via d7.

French or Caro-Kann: which should I play?

Both meet 1.e4 with ...d5 supported by a pawn. The French (...e6) gives sharper counterplay but shuts in the c8 bishop. The Caro-Kann (...c6) lets that bishop out first and leads to calmer positions.

What is the best line against the French for White?

There is no refutation. 3.Nc3 is the most testing, 3.e5 is the most straightforward plan, and 3.Nd2 avoids the Winawer pin. Pick the one whose middlegames suit you.
