How the Haxo Gambit [Bc5] c3 works
The Haxo Gambit [Bc5] c3 is a classic chess opening trap arising from the King's pawn game. 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 Nc6 3.d4 exd4 4.Bc4 Bc5 5.c3 dxc3 6.Bxf7+ Kxf7 7.Qd5+ Ke8 8.Qh5+ g6 9.Qxc5 cxb2 10.Bxb2 Nf6 11.Qc1. 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 (Scotch Gambit - Crush your opponent! - 📓 Haxo Gambit [Bc5] c3 - Theory 💡 - C44 - https://lichess.org/@/BZ333). Recognising it early lets you either spring it as Black or sidestep it as White.
