Learn How to Spot a Mate in 2: Queen Trap
This middlegame puzzle comes from the Queen's Gambit Declined, Marshall Defense and shows how active pieces can turn a material edge into a forced finish. White’s queen and rook coordination is vulnerable, and Black’s queen invasion creates a mating net around the white king. The key idea is that a seemingly greedy capture can also be a forcing move when it opens a direct line to mate. In classical chess, tactical accuracy often matters more than static material.
