How the Pirc Defence: Bxf7 Sacrifice (Gross–Geiger) works
The Pirc Defence: Bxf7 Sacrifice (Gross–Geiger) is a classic chess opening trap arising from the Pirc Defence. 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.d4 g6 3.Nf3 Bg7 4.Nc3 Nd7 5.Bc4 e5 6.Bxf7+ Kxf7 7.Ng5+ Ke8 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 (Gross - Geiger, Germany 1990). Recognising it early lets you either spring it as Black or sidestep it as White.
