King's Gambit Deflection in Chess

King’s Gambit Deflection is a tactical motif in the King’s Gambit where White sacrifices on f4 (1.e4 e5 2.f4) and then uses a follow-up move to force a crucial black piece to leave its defensive square. The defining idea is that the defender is “pulled away” (deflected) so that a threat—often against the king, the f-file, or central dark squares—can land with tempo. In many lines, the move that creates the deflection is aimed at removing control over a key square before White’s attack fully develops.
