Queens Gambit Declined Hanging Piece in Chess

In the queens gambit declined hanging piece motif, one side allows (or creates) a piece that becomes temporarily undefended after a QGD structure transition—often around the c4/d4 or c5/d5 squares. A defining feature is that after moves like 1.d4 d5 2.c4 e6 3.Nc3 Nf6 (and typical follow-ups), a tactical sequence makes a “hanging” target vulnerable to forks, pins, or winning the exchange of defenders.
