Sacrifice Puzzle (Rated 1372): Spot a Mate in 2 — King Safety

This middlegame puzzle is a sharp example of king safety deciding the game. Even when one side is materially ahead, an exposed king can make every extra piece irrelevant. The key idea is to recognize when a sacrifice opens lines around the king and forces a response that removes defenders. In classical chess, these patterns often appear after a queen invasion or when the king’s pawn shield has been weakened.
