How the French Defence: Queen Mate works
The French Defence: Queen Mate is a classic chess opening trap arising from the French Defence. In this line Black delivers checkmate on move 9, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.Nge2 dxe4 5.a3 Bxc3+ 6.Nxc3 Nc6 7.Qg4 Nxd4 8.Qxg7 Nxc2+ 9.Ke2 Qd3#. Each move looks reasonable, which is exactly why the trap is so effective over the board — White walks into it while trying to play "normal" developing moves.
This pattern is well known from master and correspondence play (Dake, A. - Pauli, 1936.??.??). Recognising it early lets you either spring it as Black or sidestep it as White.
