Queens Indian Defense Spassky System Hanging Piece in Chess

In the Queens Indian Defense Spassky System, a “hanging piece” is a tactical motif where a key piece (often a pawn or minor piece on a dark-square/central square) becomes undefended after typical development moves. The defining feature is the Spassky-style setup where Black’s pieces line up on the center/queenside, while White’s pieces may temporarily lose coordination. If White (or Black) plays a move that removes a defender or blocks a recapture, the opponent can win material by attacking the unprotected target.
