Queens Gambit Declined Exchange Variation Hanging Piece in Chess

In the queens gambit declined exchange variation, the defining feature is the early pawn exchange on d5 (typically after 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.cxd5 exd5), leading to a more open, endgame-leaning structure. A “hanging piece” here means a piece (often a pawn on d5/c4 or a minor piece tied to it) becomes undefended after the exchange sequence, so it can be won with tempo. The motif usually arises when the opponent’s pieces are not yet coordinated to cover the exchanged square(s).
