Queens Indian Accelerated Puzzle (Rated 1098): Win with a Fork — Decisive Material Gain

This middlegame puzzle shows how a single forcing check can expose loose coordination and win material. Black’s pieces are active, White’s king is still in the center, and the position contains multiple tactical hooks: a pinned knight, a trapped bishop, and overloaded defenders. The key idea is to use tempo to force the enemy queen into a passive square, then convert the pressure by winning a major piece. In classical chess, these tactical sequences often decide the game before the endgame begins.
