How the Caro-Kann Defence: Black Queen Trap works
The Caro-Kann Defence: Black Queen Trap is a classic chess opening trap arising from the Caro-Kann Defence. In this line White wins decisive material by move 10, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.e4 c6 2.d4 d5 3.exd5 cxd5 4.Bd3 Nf6 5.Bf4 Qb6 6.Nc3 e6 7.Nb5 Nc6 8.Bc7 Qa6 9.Nd6+ Bxd6 10.Bxa6. Each move looks reasonable, which is exactly why the trap is so effective over the board — Black walks into it while trying to play "normal" developing moves.
This pattern is well known from master and correspondence play (Pickett - Veatch, 1986.??.??). Recognising it early lets you either spring it as White or sidestep it as Black.
