How the King's Gambit: Wins a Pawn (CobaltBlue–Wall) works
The King's Gambit: Wins a Pawn (CobaltBlue–Wall) is a classic chess opening trap arising from the King's gambit. In this line White wins decisive material by move 11, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.e4 e5 2.f4 d5 3.exd5 e4 4.Nc3 Nf6 5.d3 Bb4 6.Bd2 O-O 7.dxe4 Re8 8.Bd3 Bxc3 9.Bxc3 Nxe4 10.Bxe4 Rxe4+ 11.Ne2 Bg4. Each move looks reasonable, which is exactly why the trap is so effective over the board — Black walks into it while trying to play "normal" developing moves.
This pattern is well known from master and correspondence play (CobaltBlue - Wall, Internet 1996). Recognising it early lets you either spring it as White or sidestep it as Black.
