French Defense Traps: 4 Real Traps for White and Black
The French Defense, 1.e4 e6, is a solid answer to 1.e4. But the pawn chains make some moves look safe when they are not. On this page you can replay 4 real French Defense traps: a check on b5 that wins the black queen, a double attack in the Rubinstein that wins a rook, the Milner-Barry Gambit, and one trap for Black against an early queen raid. Each trap is on its own board with the side lines, a Stockfish evaluation and a short "how to avoid it".

French Defense traps for White
Three traps for White. In the first two Black loses material by force. In the third, the Milner-Barry Gambit, White sacrifices a pawn and Black must find the only good squares.
WHITE TRAPTrap 1: 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.cxd4Black falls for it with 7...Nxd4? 8.Nxd4 Qxd4??9.Bb5+ - the black queen is lost
The most famous French Defense trap for White. Three black pieces hit d4, and the pawn looks free. But after the knights are traded, a bishop check on b5 opens the d-file and the white queen takes the black queen. Press Play, then try the side lines.
How to avoid it: as Black, after 7.cxd4 play 7...Bd7 first. The bishop covers b5, so the check no longer works. Then ...Nxd4 becomes a real pawn grab.
WHITE TRAPTrap 2: The Qe4 double attack (Rubinstein Variation)
1.e4 e6 2.d4 d5 3.Nc3 dxe4 ... 8.Qe2 O-O 9.Bg5Black falls for it with 9...b6??11.Qe4 - mate threat on h7 and the a8 rook hit
In the Rubinstein Variation Black castles and wants to put the bishop on b7. If Black plays ...b6 one move too early, White takes the f6 knight and Qe4 hits h7 and a8 at the same time. Press Play.
How to avoid it: as Black, play 9...c5 (or ...h6 first) before ...b6. Never open the long diagonal to the a8 rook while the white queen and bishop can come to e4 and h7.

WHITE TRAPTrap 3: The Milner-Barry Gambit
1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 5.Nf3 Qb6 6.Bd3 cxd4 7.cxd4 Bd7 8.O-OBlack grabs two pawns, then 12...Qb8?13.Qf3! - the attack rolls
This time White gives the d4 pawn on purpose. Stockfish says the gambit is not fully correct, but Black has to walk a narrow road. One natural queen move after 12.Nb5 and the black king, stuck on e8, is in real danger. Press Play.
How to avoid it: as Black, against 8.O-O you can take on d4 and answer 10.Nc3 with 10...a6, Stockfish's choice. If you take on e5 too, after 12.Nb5 the queen must go to b6.
French Defense traps for Black
Clean, forced traps for Black are rare in the French: it is a solid defence, not a gambit. The best chances come when White attacks too early. Here the white queen grabs pawns on g7 and h7 after 4.dxc5 Bxc5 5.Qg4, and Black hits back at f2.
BLACK TRAPTrap 4: Punishing the early queen raid (for Black)
1.e4 e6 2.d4 d5 3.e5 c5 4.dxc5 Bxc5 5.Qg4 Ne7White falls for it with 6.Qxg7? and 8.Nf3?8...Bxf2+ - the white king is caught in the centre
A French Defense trap for Black. White takes on c5 and sends the queen to g7 and h7. Black lets both pawns go, puts the queen on b6, and the f2 square collapses. Press Play.
How to avoid it: as White, after 4.dxc5 Bxc5 develop with Nf3 and Bd3 before any queen trip. If you did grab on g7 and h7, play 8.Nh3 to guard f2.
Where the names come from
The French Defense got its name from a correspondence match between London and Paris in 1834, in which the Paris players used it. Read the whole story and the main lines in our French Defense opening guide.
The Milner-Barry Gambit is named after Stuart Milner-Barry, an English chess player who also worked as a codebreaker at Bletchley Park in the Second World War.
The Rubinstein Variation (3...dxe4) is named after Akiba Rubinstein, one of the strongest players in the world before the First World War.
How to play the French Defense without falling into traps
Most French Defense traps come from three ideas. Learn them and you will spot the danger in time:
The check on b5. When Black's queen and knight hit d4, a white bishop on d3 can jump to b5 with check and open the d-file. Play ...Bd7 before you grab on d4.
The long diagonal. After ...dxe4 the e4 square is free for the white queen. From there it hits h7 and a8 at once. Do not play ...b6 while the white queen and bishop are aimed at h7.
The king in the centre. In the French Black often delays castling. Every pawn Black grabs costs time, and an open e-file can be fatal.
As White, the warning is the other way round: the French is a counter-punching defence. If your queen goes hunting on the kingside too early, f2 and b2 are the squares Black hits.
For plans and main lines (Winawer, Classical, Tarrasch, Exchange) read the French Defense guide. If you also play 1...c6, see our Caro-Kann traps.
French Defense Traps FAQ
What is the most famous French Defense trap?
The Bb5+ queen trap in the 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+ and the white queen on d1 takes the black queen on d4.
Is there a French Defense trap for White?
Yes. Besides the Bb5+ trap, the Rubinstein Variation has one: after 9.Bg5 b6?? 10.Bxf6 Bxf6 11.Qe4 White threatens mate on h7 and takes the rook on a8. Stockfish gives +4.2.
Are there French Defense traps for Black?
Fewer than for White, because the French is a solid defence. A good one is against the early queen raid: 4.dxc5 Bxc5 5.Qg4 Ne7 6.Qxg7? Rg8 7.Qxh7 Qb6 8.Nf3? Bxf2+ and the white king is stuck in the centre.
Is the Milner-Barry Gambit good?
It is a dangerous practical weapon, but Stockfish does not trust it fully: after 8...Nxd4 9.Nxd4 Qxd4 10.Nc3 a6 Black is better (about -0.9). If Black grabs e5 as well, one wrong queen move can lose.
How do I avoid the Bb5+ trap in the French Advance?
Play 7...Bd7 before you take on d4. The bishop on d7 covers b5, so the check is gone and the d4 pawn becomes a real target.
What is the difference between French Defense and French Defence?
Nothing. "Defense" is the American spelling and "Defence" the British one. Both mean 1.e4 e6, and the traps on this page work under either name.
