Queens Gambit Declined Manhattan Variation Puzzle (Rated 1074): Win a Fork — Decisive Material Gain

This puzzle shows a classic opening tactic where active queen play creates a forcing check and wins material by exploiting a pinned piece. White’s queen jumps into the attack while Black’s bishop on b4 is overloaded and the knight on c3 is tied to the king. In classical chess, these tactical motifs often appear when development is lagging and the king remains in the center. The key idea is to use tempo, forcing moves, and piece coordination to convert activity into a concrete material edge.
