King's Gambit Intermezzo in Chess

The King’s Gambit Intermezzo is an intermezzo motif in the King’s Gambit where one side inserts a forcing move (often with tempo) before the opponent can complete the expected recapture or follow-up. In the classic structure, after 1.e4 e5 2.f4 exf4, the defining idea is to play an additional threat or check/attack that changes the timing of the usual ...g5 or ...Nf6 recapture sequence.
