Kings Gambit Pin in Chess

A kings gambit pin is a tactical motif in the King’s Gambit where the early pawn sacrifice (1.e4 e5 2.f4) leads to a pin against the king-side pieces—most often by using a bishop or queen line to immobilize a defender. The defining feature is that after the gambit, a piece that must move to respond to a threat becomes pinned to a more valuable target (commonly the king or a major piece).
