How the Queen's Pawn Game: Wins a Piece (LordVader–Wall) works
The Queen's Pawn Game: Wins a Piece (LordVader–Wall) is a classic chess opening trap arising from the Queen's pawn game. In this line Black wins decisive material by move 7, punishing a natural-looking but losing idea from White.
The full sequence runs 1.d4 Nf6 2.Bf4 d5 3.Nf3 c5 4.dxc5 e6 5.Na3 Bxc5 6.Nb5 Qa5+ 7.c3 Qxb5. 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 (LordVader - Wall, Internet 1996). Recognising it early lets you either spring it as Black or sidestep it as White.
