How the King's Indian Defence: Opening Trap (Atkins–Conde) works
The King's Indian Defence: Opening Trap (Atkins–Conde) is a classic chess opening trap arising from the King's Indian defence. In this line White wins decisive material by move 13, 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.f4 O-O 6.Nf3 Re8 7.Be2 Nbd7 8.e5 Ng4 9.e6 Ndf6 10.exf7+ Kxf7 11.h3 Nh6 12.g4 Nd7 13.Ng5+. 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 (Atkins - Conde, 1925.??.??). Recognising it early lets you either spring it as White or sidestep it as Black.
