How the King's Pawn Opening: Opening Trap works
The King's Pawn Opening: Opening Trap is a classic chess opening trap arising from the King's pawn opening. In this line White wins decisive material by move 6, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.e4 Nc6 2.d4 b6 3.c3 Bb7 4.Nf3 Nf6 5.e5 Nh5 6.g4. 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 (Wall - Trogdon, Dayton 1980). Recognising it early lets you either spring it as White or sidestep it as Black.
