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 deliver a forced finish, while the defender’s king has no useful escape squares. In classical chess, these moments often come from active piece coordination, loose back-rank control, or a pinned defender that can no longer help. The key is to scan for direct checks first, then verify whether every flight square and capture is covered. When the position is already tactically overloaded, the winning move can be immediate.
