How the Bxf7 Sacrifice #2 works
The Bxf7 Sacrifice #2 is a classic chess opening trap. In this line White wins decisive material by move 13, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.g4 d5 2.Bg2 Bxg4 3.c4 e6 4.Qb3 Nc6 5.cxd5 exd5 6.Bxd5 Bd6 7.Bxf7+ Kf8 8.Bxg8 Rxg8 9.Qxb7 Ne5 10.d4 Ng6 11.Nc3 Kf7 12.h3 Bh5 13.Qd5+. 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 (Wall, Bill - Ukralex, 1997.??.??). Recognising it early lets you either spring it as White or sidestep it as Black.
