Blackmar Diemer Gambit Other Variations Puzzle (Rated 891): Crush with a Fork — Decisive Material Gain
This middlegame puzzle is a classic example of a crushing fork that wins material by exploiting king safety. White’s active pieces coordinate against a loose black king and overloaded defenders, creating a forcing sequence that starts with check and ends with a major tactical gain. The key idea is not slow maneuvering, but using a forcing move to drag the king into a worse square and then collect a hanging piece while Black’s pieces remain awkwardly placed.
