Learn How to Spot a Mate in 4: Exposed King

This puzzle is a classic attacking finish against an exposed king. Black’s heavy pieces are coordinated to force the white king into a narrow corridor, where every escape square is controlled. The key idea is not raw material, but forcing play: checks, captures, and threats that leave the defender with no useful reply. In classical chess, these mating nets often appear when the king’s pawn shield is weakened and the attacking rook and queen can work together.
