Queen's Gambit Declined Exchange Sacrifice Chess Puzzles

The Queen's Gambit Declined Exchange Sacrifice is a motif where Black gives up a rook for a minor piece, usually on c3 or c4, to damage White's structure or win key central control. It often appears after the Queen's Gambit Declined setup, especially when White has a c-pawn or d-pawn target and Black can trade material for long-term positional compensation.
