Mate In 2 Puzzle (Rated 1489): Spot Mate in 2 — Queen Sacrifice

This chess puzzle is a classic forcing finish built around king safety and a sacrifice that drags the enemy king onto a vulnerable square. Even though the material balance may look close, the exposed king and loose back rank make the position tactically winning. In practical terms, this is the kind of chess endgame or middlegame position where activity matters more than material, and one forcing check can decide everything immediately.
