How the King's Indian Defence: Opening Trap (Wall–Gant) works
The King's Indian Defence: Opening Trap (Wall–Gant) is a classic chess opening trap arising from the King's Indian defence. In this line White wins decisive material by move 10, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.h3 b6 7.Bd3 c5 8.e5 dxe5 9.dxe5 Nfd7 10.Be4. 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 - Gant, North Carolina 1978). Recognising it early lets you either spring it as White or sidestep it as Black.
