How the Queen's Gambit Accepted: Bxf7 Sacrifice (Sajtar–Sliwe) works
The Queen's Gambit Accepted: Bxf7 Sacrifice (Sajtar–Sliwe) is a classic chess opening trap arising from the Queen's gambit accepted. In this line Black wins decisive material by move 12, punishing a natural-looking but losing idea from White.
The full sequence runs 1.d4 d5 2.c4 dxc4 3.Nf3 Nf6 4.Qa4+ Nbd7 5.Nc3 e6 6.e4 c5 7.d5 exd5 8.e5 d4 9.Bxc4 dxc3 10.Ng5 Qe7 11.Bxf7+ Kd8 12.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 (Sajtar - Sliwe, Warsaw 1947). Recognising it early lets you either spring it as Black or sidestep it as White.
