Learn How to Spot Mate in 1: King Safety
This middlegame puzzle is a pure king-safety test: one side’s pieces are coordinated around the enemy king, and the final blow is immediate. In positions like this, material counts less than the geometry of the board. Look for lines, diagonals, and squares that are already controlled by your heavy pieces and bishops. When the opposing king has limited escape squares and key defenders are overloaded, a forcing check can end the game at once.
