How the Nimzo-Indian Defence: Opening Trap #2 works
The Nimzo-Indian Defence: Opening Trap #2 is a classic chess opening trap arising from the Nimzo-Indian Defence. In this line Black wins decisive material by move 8, punishing a natural-looking but losing idea from White.
The full sequence runs 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.g3 c5 5.Nf3 cxd4 6.Nxd4 Ne4 7.Qc2 Qa5 8.Nb3 Qf5. 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 (Van Mil - Witt). Recognising it early lets you either spring it as Black or sidestep it as White.
