Learn How to Spot a Mate in 2: Kill Box Mate
This chess puzzle is a classic mating net in a sharp middlegame-to-endgame setting. White’s queen and rook coordinate to restrict the enemy king’s escape squares, creating a kill box around the monarch. The key idea is not material gain but forcing checks that leave the king with no safe flight squares. In classical chess, these patterns often appear when the king is exposed and your heavy pieces can dominate open lines.
