Stonewall Attack Puzzle (Rated 899): Win with a Fork — Decisive Material Gain
This Queen's Pawn Game middlegame shows how a single tactical shot can turn a balanced-looking position into a decisive material win. Black’s active pieces coordinate against White’s king safety, and the key idea is a fork that hits multiple high-value targets at once. In practical terms, the attack works because White’s pieces are overloaded and the king lacks enough shelter. Once the tactical sequence starts, White is forced into a simplification that leaves Black with a winning advantage.
