How the Philidor's Defence: Bxf7 Sacrifice #3 works
The Philidor's Defence: Bxf7 Sacrifice #3 is a classic chess opening trap arising from the Philidor's defence. In this line Black wins decisive material by move 11, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 e5 2.Nf3 d6 3.d4 Nd7 4.Bc4 c6 5.O-O Be7 6.dxe5 dxe5 7.Qe2 Ngf6 8.Rd1 Qc7 9.Ng5 O-O 10.Bxf7+ Rxf7 11.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 (Fischer, Robert - Fine, R., 1963.??.??). Recognising it early lets you either spring it as Black or sidestep it as White.
