How the King's Gambit: Wins the Exchange works
The King's Gambit: Wins the Exchange is a classic chess opening trap arising from the King's gambit. In this line Black wins decisive material by move 5, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 e5 2.f4 Nc6 3.fxe5 Qh4+ 4.g3 Qxe4+ 5.Qe2 Qxh1. 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 (Boldman - Jansson, 1937). Recognising it early lets you either spring it as Black or sidestep it as White.
