Modern Defense Standard Line Fork Puzzle (Rated 1361): Spot — Mate in 3

This middlegame puzzle is a classic mating net built around an advanced pawn, an exposed king, and forcing checks. White’s queen and bishop coordinate to overload the defender and create a direct attack on the king’s shelter. The key idea is not material gain, but using a passed pawn and active pieces to force the king into a corner where escape squares disappear. Patterns like exposed king, removal of the defender, and long mate are all present.
