Why does 6.Nxd5 lose a piece in the Elephant Trap? After 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Nbd7 5.cxd5 exd5, White's 6.Nxd5? Nxd5 7.Bxd8 Bb4+ 8.Qd2 Kxd8 leaves White a piece down. Stockfish 18 rates it -3.8 for White. Black does not take back on d1 at once: the bishop check wins the queen back first. White fell in 103 of 891 games (11.6%).
The trap
- d4 d5
- c4 e6
- Nc3 Nf6
- Bg5 Nbd7
- cxd5 exd5
- Nxd5? Nxd5
- Bxd8 Bb4+
- Qd2 Bxd2+
- Kxd2 Kxd8
The knight on f6 looks pinned to the queen by the bishop on g5, so White's capture on d5 seems to win a pawn. But the pin is not real: Black simply takes the knight on d5, White takes the queen, and 7...Bb4+ forces the queen trade on d2. The queens and bishops are traded off, and Black is left with White's knight for a pawn.
The safe moves
White has plenty. Of 36 legal moves in the position after 5...exd5, 26 keep the evaluation within one pawn of the best. The best is 6.e3 (+0.3), then 6.Qc2 and 6.Nf3. Ten moves lose more than a pawn, 6.Nxd5 above all.
Safe line: 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Nbd7 5.cxd5 exd5 6.e3 Be7 7.Bd3 c6 8.Nf3 O-O 9.O-O Ne8 10.Bf4 Bd6

Source: 3,062,092 rated Lichess games, September 2026. At 2200+ the position appears in 1 game in 870 (11.5 per 10,000), more than at any other level, because strong players pick the Queen's Gambit Declined. They also fall for it least, at 3%.
This is a trap for strong players to know, not a weapon for beginners: it needs a Queen's Gambit Declined and a White player who takes a pawn without looking.
The rule
A pinned piece may still be able to move if the move wins something bigger. Before taking a "free" pawn, check whether the pin is real. Ask what happens after you take, they recapture, and you take the queen.
