King's Gambit Hanging Piece in Chess

In the King’s Gambit, a “King’s Gambit Hanging Piece” is a tactical moment where a piece (often the pawn or a developed minor piece) is left undefended after the defining sacrifice sequence (e.g., 1.e4 e5 2.f4 exf4). The key feature is that the opponent can capture it immediately, but doing so changes the balance—often exposing the king or opening lines for your attack.
