How the Dutch: Bishop Mate (Teed–Delmar) works
The Dutch: Bishop Mate (Teed–Delmar) is a classic chess opening trap arising from the Dutch. In this line White delivers checkmate on move 8, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.d4 f5 2.Bg5 h6 3.Bh4 g5 4.Bg3 f4 5.e3 h5 6.Bd3 Rh6 7.Qxh5+ Rxh5 8.Bg6#. 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 (Teed - Delmar, 1896.??.??). Recognising it early lets you either spring it as White or sidestep it as Black.
