Modern Defense Mongredien Defense Puzzle (Rated 1149): Win Material — Crushing Fork
This middlegame puzzle is a classic example of a crushing fork that wins material by attacking two valuable targets at once. Black’s active knight jumps into the white camp with tempo, creating a direct tactical refutation of White’s loose coordination. The position also shows how an exposed king, active queen, and overloaded rooks can become vulnerable when one forcing move appears. In practical play, this is the kind of tactical shot that turns a slightly better position into a decisive advantage.
