Sacrifice Puzzle (Rated 1586): Mate in 3 — Pillsbury's Mate

This puzzle is a classic mating attack built around king safety, piece coordination, and a forcing sacrifice. White’s queen and rook work together to overload the defender and drag the king into a vulnerable line. The key idea is that the defending king cannot safely accept the sacrifice because the follow-up attack creates a mating net. In classical chess, these patterns often appear when the enemy king has weakened pawn cover and your heavy pieces are already active.
