How the Attack on f7 works
The Attack on f7 is a classic chess opening trap arising from the Philidor's defence. In this line White wins decisive material by move 11, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.e4 e5 2.Nf3 d6 3.Bc4 c6 4.d4 Nd7 5.c3 Be7 6.Qb3 d5 7.exd5 b5 8.Bd3 exd4 9.cxd4 c5 10.Bxb5 Nf6 11.Bc6. Each move looks reasonable, which is exactly why the trap is so effective over the board — Black walks into it while trying to play "normal" developing moves.
This pattern is well known from master and correspondence play (50 Opening Traps,Part 1 - Attack on f7 - C41 - https://lichess.org/@/CHESSLUCAFD). Recognising it early lets you either spring it as White or sidestep it as Black.
