Rat Defense Mate In 2 Beginner Puzzle (Rated 1119): Spot a Mate in 2 — Discovered Attack

This puzzle is a classic middlegame mating net built around a discovered attack and a forcing check. The key idea is that one piece’s move opens a line for another attacker, creating immediate threats against the king. Because the king is exposed and several pieces are overloaded or pinned, the defender has very limited options. In classical chess, these patterns often appear when active pieces coordinate against a weakened king shelter and a trapped defender.
