How the Petrov's Defence: Bxf7 Sacrifice (Tg–Lai) works
The Petrov's Defence: Bxf7 Sacrifice (Tg–Lai) is a classic chess opening trap arising from the Petrov's 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 e5 2.Nf3 Nf6 3.Bc4 Nxe4 4.Bxf7+ Kxf7 5.Nxe5+ Kg8 6.O-O d6 7.Qe2 dxe5 8.Qc4+. 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 (Tg - Lai, Kual Lumpar 1992). Recognising it early lets you either spring it as Black or sidestep it as White.
