How the King's Knight Opening: Nxf2 Sacrifice works
The King's Knight Opening: Nxf2 Sacrifice is a classic chess opening trap arising from the King's knight opening. 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 e5 2.Nf3 f5 3.Bc4 d5 4.Bxd5 Nf6 5.Bb3 Nxe4 6.Nxe5 Nxf2 7.Qh5+ g6 8.Bf7+ Ke7 9.Qg5+ Kd6 10.Qxd8+. 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 (Robins - Anders, 1970.??.??). Recognising it early lets you either spring it as White or sidestep it as Black.
