How the Sicilian Defence: Bxf7 Sacrifice (Kvist–Johannson) works
The Sicilian Defence: Bxf7 Sacrifice (Kvist–Johannson) is a classic chess opening trap arising from the Sicilian Defence. 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 c5 2.d4 cxd4 3.c3 dxc3 4.Nxc3 d6 5.Nf3 Nf6 6.Bc4 Nc6 7.e5 Nxe5 8.Nxe5 dxe5 9.Bxf7+ Kxf7 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 (Kvist - Johannson, 1958.??.??). Recognising it early lets you either spring it as White or sidestep it as Black.
