Learn How to Spot a Mate in 1: King Safety
This middlegame puzzle is a pure king-safety lesson: one side’s king is boxed in, while the attacking pieces already control the key entry squares around it. In positions like this, material counts matter far less than the geometry around the king. When a queen, bishop, or rook can coordinate on a vulnerable target square, the game can end immediately. The best practical habit is to scan for forcing checks first, especially when the opponent’s king has limited escape squares.
