How the Two Knights Defence: White Queen Trap works

The Two Knights Defence: White Queen Trap is a classic chess opening trap arising from the Two Knights Defence. In this line Black wins decisive material by move 9, punishing a natural-looking but losing idea from White.

The full sequence runs 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d3 d5 5.exd5 Nxd5 6.O-O Bg4 7.Re1 f6 8.Nxe5 Bxd1 9.Nxc6+. 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 (Armas - Hartung, 1988.??.??). Recognising it early lets you either spring it as Black or sidestep it as White.
