Learn How to Spot Mate in 1: King Safety
This middlegame puzzle is a pure tactical finish built around king safety. Even when material is equal, a vulnerable king and active pieces can create a forced checkmate in a single move. The key is to look for checks that exploit weak squares, overloaded defenders, and pieces that restrict escape routes. In classical chess, these patterns often appear suddenly after one side’s king becomes boxed in by its own pieces and pawns.
