Learn How to Spot Mate in 1: Mating Net
This puzzle is a classic middlegame mating net where the king is boxed in by its own pieces and pawns. The key idea is that a single forcing move can exploit the exposed king, overloaded defenders, and the lack of escape squares. Even with material deficits, direct king attack can override everything else when the final square is covered and the checking piece cannot be captured or blocked.
