Queen's Gambit Declined: Harrwitz Attack
Overview
Queen's Gambit Declined: Harrwitz Attack is a gambit, classified under ECO code D37 within the Closed & Semi-Closed Games family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.
