How the King's Pawn Opening: Bxf7 Sacrifice (Klabunde–Snyder) works
The King's Pawn Opening: Bxf7 Sacrifice (Klabunde–Snyder) is a classic chess opening trap arising from the King's pawn opening. In this line Black wins decisive material by move 8, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 d6 2.Nf3 Nd7 3.Nc3 g6 4.Bc4 Bg7 5.d4 a5 6.Ng5 Nh6 7.Bxf7+ Nxf7 8.Ne6. 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 (Klabunde - Snyder, Denver 1983). Recognising it early lets you either spring it as Black or sidestep it as White.
