Deflection Puzzle (Rated 1219): Force Mate in 3 — Pillsbury's Mate

This puzzle is a classic forcing attack where the queen and rook coordinate to drag the enemy king into a mating net. The key idea is deflection: a defender is lured away from a critical square so the final check becomes unavoidable. In middlegame positions like this, king safety matters more than material, and a temporary queen sacrifice can be the fastest path to checkmate. The pattern is closely related to Pillsbury's Mate and other classical mating motifs.
