How the Queen's Pawn Game: Opening Trap #3 works
The Queen's Pawn Game: Opening Trap #3 is a classic chess opening trap arising from the Queen's pawn game. In this line Black wins decisive material by move 6, punishing a natural-looking but losing idea from White.
The full sequence runs 1.d4 Nf6 2.Bg5 d5 3.e3 e6 4.c4 c6 5.Bd3 dxc4 6.Bxc4 Qa5+. 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 (Wall, Bill - Buchanan, 1976.??.??). Recognising it early lets you either spring it as Black or sidestep it as White.
