King's Gambit Pin in Chess

A King’s Gambit Pin is a tactical motif that arises from the King’s Gambit’s early pawn sacrifice (1.e4 e5 2.f4). After moves like 2...exf4 and subsequent development, a piece (often a bishop or queen) pins an enemy piece to the king—commonly along a diagonal or file—so the pinned piece can’t move without exposing the king. The defining feature is that the gambit’s open lines enable a pin that wins time, material, or decisive initiative.
