English Opening Anglo Grunfeld Defense Puzzle (Rated 1007): Crush with a Fork — Decisive Material Gain
This middlegame puzzle is a classic example of a crushing fork that wins material by forcing the king into a bad square and then exploiting the overloaded position. Black’s active pieces create immediate tactical pressure against White’s queen and king, turning a seemingly balanced material situation into a decisive advantage. The key idea is that a forcing check can improve piece coordination while also trapping a major piece and exposing the king to follow-up threats.
