Queen's Gambit Declined Marshall Defense Puzzle (Rated 1214): Win Material — Classical Chess Tactics
This middlegame puzzle is a classic example of tactical punishment against an exposed king and overloaded defender. White’s queen and rook are active on open files, and Black’s queen is tied to key defensive duties while the king remains vulnerable in the center. The winning idea is a forcing sequence that uses check, capture, and a follow-up attack on a loose piece. It is a strong example of how material gains often come from king safety and piece coordination rather than a direct attack on the king.
