Learn How to Spot Mate in 1: King Safety
This middlegame puzzle is all about king safety and forcing moves. Even when one side is materially ahead, a vulnerable king can end the game instantly if the defender’s pieces are overloaded or poorly coordinated. Look for checks first, then ask whether the king has any legal escape squares, captures, or blocks. In classical chess, these one-move finishes often come from a mating net built by active pieces and open lines.
