How the King's Gambit: Bxf7 Sacrifice works
The King's Gambit: Bxf7 Sacrifice is a classic chess opening trap arising from the King's gambit. In this line Black wins decisive material by move 13, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 e5 2.f4 exf4 3.Nf3 Be7 4.Bc4 Nf6 5.Nc3 Nxe4 6.Bxf7+ Kxf7 7.Ne5+ Ke6 8.Qg4+ Kxe5 9.d4+ Kxd4 10.Be3+ Ke5 11.Bxf4+ Kf6 12.Bxc7 Qxc7 13.Nd5+. 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 (Teschner - NN, 1951.??.??). Recognising it early lets you either spring it as Black or sidestep it as White.
