How the Two Knights Defence: Bxf2 Sacrifice (Crowley–Wall) works
The Two Knights Defence: Bxf2 Sacrifice (Crowley–Wall) is a classic chess opening trap arising from the Two Knights Defence. In this line White wins decisive material by move 8, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5 5.Nxf7 Bxf2+ 6.Kf1 Qe7 7.Nxh8 d5 8.Bxd5 Bg4. 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 (Crowley - Wall, Internet 1996). Recognising it early lets you either spring it as White or sidestep it as Black.
