Queens Gambit Declined Three Knights Variation Hanging Piece in Chess

In the queens gambit declined three knights variation, the key tactical idea behind a “hanging piece” is that after the defining development moves (…Nf6, …Be7, and typical central tension), one of your pieces can be left en prise. A common target is the c4/d4 area or a recently moved knight that lacks protection, so the opponent can capture it immediately or with tempo. The motif is about creating (or exploiting) a position where a piece is attacked but not adequately defended.
