How the King's Pawn Opening: Wins a Pawn (O. Smith–Bej) works
The King's Pawn Opening: Wins a Pawn (O. Smith–Bej) is a classic chess opening trap arising from the King's pawn opening. In this line Black wins decisive material by move 6, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 b6 2.Bc4 Bb7 3.Nf3 Bxe4 4.Ng5 Bg6 5.h4 f6 6.h5. 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 (O. Smith - Bej, Philadelphia 1898). Recognising it early lets you either spring it as Black or sidestep it as White.
