How the Queen's Pawn Opening: Wins a Piece works
The Queen's Pawn Opening: Wins a Piece is a classic chess opening trap arising from the Queen's Pawn Opening. In this line Black wins decisive material by move 9, punishing a natural-looking but losing idea from White.
The full sequence runs 1.d4 d5 2.Nf3 Bg4 3.c4 e6 4.Ne5 Bf5 5.cxd5 exd5 6.Qb3 b6 7.e4 Bxe4 8.Bb5+ Ke7 9.Bc6 10.Nxc6+. 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 (Bernstein - Unknown, Berlin 1903). Recognising it early lets you either spring it as Black or sidestep it as White.
