Queens Gambit Declined Marshall Defense Discovered Attack Chess Puzzles

In the Queens Gambit Declined Marshall Defense, a discovered attack appears when a piece moves out of the way and reveals a stronger line from a rook, bishop, or queen onto a valuable target. The defining feature is that the Marshall setup often creates tense central and queenside piece placement, so one tempo can uncover a direct attack on the king, queen, or a pinned piece. For an intermediate player, this motif usually means using a developing move or capture to open a line while simultaneously threatening something behind it.
