Learn How to Spot Mate in 1: King Safety
This chess endgame puzzle is a classic example of king safety deciding everything. Even with material close to balanced, one exposed king can lose immediately if the attacking queen has access to a decisive checking square. The key idea is to look for forcing moves first, especially checks that cannot be met by interposition or capture. In practical classical chess, these one-move finishes often appear when the defender’s pieces are overloaded or the king’s escape squares are cut off.
