Carr Defense Puzzle (Rated 889): Fork — Decisive Material Gain

This middlegame puzzle is built around a forcing fork that wins material by attacking two key targets at once. Black’s active knight jumps into the heart of White’s position, creating a tactical imbalance that overrides White’s extra material. The position also shows why king safety and piece activity can matter more than raw count: White’s queen and bishop are vulnerable to a tactical strike, while Black’s pieces are coordinated for a direct win of material.
