How the King's Pawn Opening: Wins a Pawn (Wall–J. Reyes) works
The King's Pawn Opening: Wins a Pawn (Wall–J. Reyes) is a classic chess opening trap arising from the King's pawn opening. In this line Black wins decisive material by move 7, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 d6 2.d4 g6 3.Nc3 Bg7 4.Bc4 c6 5.Nf3 b5 6.Nxb5 cxb5 7.Bd5. 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 - J. Reyes, San Antonio 1993). Recognising it early lets you either spring it as Black or sidestep it as White.
