Sacrifice Puzzle (Rated 1415): Spot a Mate in 2 — King Safety

This middlegame puzzle is a classic example of how king safety can outweigh material. Even when the position looks balanced, active pieces around the enemy king can create a forced mating net. The key idea is to notice when a tactical sacrifice opens lines and removes defenders at the same time. In classical chess, these patterns often appear after a trigger move that exposes the king and makes every defensive resource too slow.
