How the Queen's Pawn Game: Wins a Pawn (Kennedy–Goldberg) works
The Queen's Pawn Game: Wins a Pawn (Kennedy–Goldberg) is a classic chess opening trap arising from the Queen's pawn game. 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.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Qxf3 Qxd4 6.Be3 Qb4 7.O-O-O Bg4 8.Nb5 Nfd7 9.Qxb7. 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 (Kennedy - Goldberg, New Jersey 1992). Recognising it early lets you either spring it as Black or sidestep it as White.
