How the Old Indian Defence: White Queen Trap works
The Old Indian Defence: White Queen Trap is a classic chess opening trap arising from the Old Indian Defence. In this line Black wins decisive material by move 11, punishing a natural-looking but losing idea from White.
The full sequence runs 1.d4 Nf6 2.c4 d6 3.Nc3 e5 4.dxe5 dxe5 5.Bg5 Nbd7 6.Nf3 c6 7.Ne4 Nxe4 8.Bxd8 Bb4+ 9.Nd2 Bxd2+ 10.Qxd2 Nxd2 11.Kxd2 Kxd8. Each move looks reasonable, which is exactly why the trap is so effective over the board — White walks into it while trying to play "normal" developing moves.
This pattern is well known from master and correspondence play (Koukolik - Sykora, 1994). Recognising it early lets you either spring it as Black or sidestep it as White.
