Learn How to Crush a Fork: Decisive Material Gain
This middlegame puzzle shows how a single forcing move can turn active piece placement into a decisive material gain. The key idea is a crushing fork: one piece gives check while also creating a second threat against a valuable target. In positions like this, the side to move often exploits king safety, loose pieces, and overloaded defenders. Even when one side is materially ahead, tactical accuracy can instantly reverse the evaluation and win the game.
