How the King's Pawn Opening: Bishop Mate works
The King's Pawn Opening: Bishop Mate is a classic chess opening trap arising from the King's pawn opening. In this line Black delivers checkmate on move 11, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 Nc6 2.d4 d5 3.exd5 Qxd5 4.Nf3 Bg4 5.Nc3 Bxf3 6.Nxd5 Bxd1 7.Nxc7+ Kd8 8.Nxa8 Bxc2 9.Bf4 Nxd4 10.Nc7 e5 11.Bxe5 Bb4#. 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 (50 Opening Traps,Part 1 - what, checkmate? - B00 - https://lichess.org/@/CHESSLUCAFD). Recognising it early lets you either spring it as Black or sidestep it as White.
