Pillsburys Mate Intermediate Puzzle (Rated 974): Spot Pillsbury's Mate — Mate in 2

This puzzle is a classic mating net in a middlegame position where active pieces coordinate against an exposed king. The key idea is to use a forcing check that drags the king into a worse square, then finish with a rook on the open file. Patterns like this often appear when one side has better piece activity, a weakened king shelter, and a line that can be opened with tempo. It is a textbook example of a short tactical refutation.
