The French Defence is a chess opening characterised by the moves:
The French has a reputation for solidity and resilience, though it can result in a somewhat cramped game for Black in the early stages. Black often gains counterattacking possibilities on the queenside while White tends to concentrate on the kingside.
Following the opening moves 1.e4 e6, the game usually continues 2.d4 d5 (see below for alternatives). White makes a claim to the centre, while Black immediately challenges the pawn on e4.
White's options include defending the e4 pawn with 3.Nc3 or 3.Nd2, exchanging with 3.exd5, or advancing the pawn with 3.e5, each of which lead to different types of positions. Note that 3.Bd3 allows 3...dxe4 4.Bxe4 Nf6, after which White must concede to Black either a tempo or the advantage of the two bishops.
See the diagram for the pawn structure most typical of the French. Black has more space on the queenside, so tends to focus on that side of the board, almost always playing ...c7–c5 at some point to attack White's pawn chain at its base, and may follow up by advancing his a- and b-pawns.
Alternatively or simultaneously, Black will play against White's centre, which is cramping his position. The flank attack ...c7–c5 is usually insufficient to achieve this, so Black will often play ...f7–f6. If White supports the pawn on e5 by playing f2–f4, then Black has two common ideas. Black may strike directly at the f-pawn by playing ...g7–g5. The pawn on g5 may also threaten to advance to g4 to drive away a white knight on f3, augmenting Black's play against the White centre. Another idea is to play ...fxe5, and if White recaptures with fxe5, then Black gains an open f-file for his rook. Then, as White usually has a knight on f3 guarding his pawns on d4 and e5, Black may sacrifice the exchange with ...Rxf3 to destroy the white centre and attack the king. On the other hand, if White plays dxe5, then the a7–g1 diagonal is opened, making it less desirable for White to castle kingside.
