How the King's Pawn Opening: Bxf7 Sacrifice (Lusgin–Joffe) works
The King's Pawn Opening: Bxf7 Sacrifice (Lusgin–Joffe) is a classic chess opening trap arising from the King's pawn opening. In this line Black wins decisive material by move 5, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 d6 2.Nf3 g6 3.Bc4 Nd7 4.Bxf7+ Kxf7 5.Ng5+. 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 (Lusgin - Joffe, Minsk 1968). Recognising it early lets you either spring it as Black or sidestep it as White.
