Learn How to Spot Mate in 1: King Safety
This middlegame puzzle is a pure tactical finish built around king safety. The key idea is that a defended-looking position can still collapse when the enemy king has no safe squares and the surrounding pieces are overworked. In classical chess, these one-move finishes often come from a forcing check that cannot be answered because every escape square is covered. The position rewards pattern recognition more than calculation, since the mating net is already fully formed.
