Mate In 3 Puzzle (Rated 1369): Spot Mate in 3 — Back Rank Mate

This classical chess puzzle is a sharp middlegame example of a mating net built around king safety and piece coordination. White’s material edge looks huge, but the real story is Black’s active bishops and queen creating a forcing attack on the back rank and nearby escape squares. The key idea is to use checks and tactical threats to restrict the king, overload defenders, and convert activity into a forced mate in 3.
