Learn How to Spot Mate in 1: King Safety
This middlegame puzzle is a pure king-safety lesson: one side’s pieces are ideally placed to exploit a weakened king shelter, and the position collapses immediately under a direct mating threat. The key idea is to look for forcing moves first, especially checks that limit the king’s escape squares. Even when material is roughly balanced, active queen and knight coordination can create a decisive finish if the enemy king has no flight squares and its defenders are overloaded or pinned.
