Pillsbury's Mate Puzzle (Rated 890): Force a Mate — Mate in 2

This chess endgame puzzle is a classic forcing attack where king safety matters more than material. White’s pieces are already aimed at the enemy king, and the key idea is to use a sacrifice to drag a defender away from the back rank and open a direct mating line. In classical chess, these patterns often appear when the king is boxed in and one tactical blow creates an unavoidable finish.
