Bird Opening Wagner Zwitersch Gambit Hanging Piece in Chess

In the Bird Opening: Wagner–Zwitersch Gambit, the “hanging piece” motif refers to a tactical moment where a key piece (often a minor piece or pawn) becomes undefended after the gambit sequence. The defining feature is that Black’s compensation and piece activity create a position where White can attack a piece that has lost protection, forcing it to move or be lost.
