How the King's Pawn Opening: Bxf7 Sacrifice (Miannay–Brunneay) works
The King's Pawn Opening: Bxf7 Sacrifice (Miannay–Brunneay) is a classic chess opening trap arising from the King's pawn opening. 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 d6 2.Nf3 g6 3.Bc4 Bg4 4.Bxf7+ Kxf7 5.Ng5+ Ke8 6.Qxg4 Nf6 7.Qe6 Qd7 8.Qf7+ Kd8 9.Ne6+ Kc8 10.Nxf8. 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 (Miannay - Brunneay, Torcy 1991). Recognising it early lets you either spring it as White or sidestep it as Black.
