How the Kortchnoi Trap (Dutch Defense) works
The Kortchnoi Trap (Dutch Defense) is a classic chess opening trap arising from the Dutch. In this line White delivers checkmate on move 7, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.d4 f5 2.h3 Nf6 3.g4 fxg4 4.hxg4 Nxg4 5.Qd3 Nf6 6.Rxh7 Rxh7 7.Qg6#. 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.
Recognising this pattern early lets you either spring it as White or calmly sidestep it when you are Black.
