Fool's Mate Puzzle (Rated 1500): Mate in 3 — Back Rank Mate

This puzzle is a classic mating net built around king safety and forcing checks. Black’s heavy pieces coordinate to restrict the white king’s escape squares while a pinned bishop and overloaded defenders limit defensive resources. Even though White has extra material, the attack is more important than static evaluation. The key idea is that a forcing check can drive the king into a tighter box, where the next move creates a direct mating threat on the back rank and along the open file.
