Queen's Gambit Declined Attacking Pinned Piece Chess Puzzles

In the Queen's Gambit Declined, an attacking pinned piece motif appears when Black or White uses a pin on a key defender and then increases pressure against that immobilized piece. A defining feature is the classic QGD structure after 1.d4 d5 2.c4 e6, where a bishop, knight, or queen can pin a piece to the king or queen and make it a tactical target.
