How the King's Knight Opening: White Queen Trap works
The King's Knight Opening: White Queen Trap is a classic chess opening trap arising from the King's knight opening. In this line White wins decisive material by move 9, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.e4 e5 2.Nf3 f5 3.exf5 Bc5 4.Nxe5 d5 5.Qh5+ Ke7 6.Qg5+ Ke8 7.Qxd8+ Kxd8 8.Nf7+ Ke7 9.Nxh8. 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 (Valverde - Rosso, 1998.??.??). Recognising it early lets you either spring it as White or sidestep it as Black.
