Pillsbury's Mate Puzzle (Rated 815): Spot Mate in 2 — Queen Sacrifice

This puzzle is a classic forcing sequence in a simplified middlegame/endgame setting, where king safety matters more than material count. The key idea is to use a powerful queen sacrifice to drag the enemy king or a key defender onto a vulnerable square, then finish with a rook-based mating net. These patterns often appear in classical chess when open files, weak back-rank squares, and overloaded defenders combine into a direct tactical win.
