King's Indian Attack Puzzle (Rated 1079): Crush with a Fork — Decisive Material Gain

This middlegame puzzle is a classic example of a crushing fork that converts activity into decisive material gain. White’s pieces are active, Black’s king is slightly exposed to tactical pressure, and the key defender is overloaded. The winning idea is based on forcing checks and captures that create a discovered attack on loose pieces. In positions like this, a single tactical sequence can swing the game by winning major material and leaving the opponent’s coordination shattered.
