Learn How to Triangle Mate: Mate in 2
This middlegame puzzle is a classic example of a forcing mating net built around king safety and piece activity. White’s pieces coordinate to create a direct attack on the exposed king, with the rook and queen working together to exploit the weakened dark squares and the overloaded defenders around the black king. The key idea is not material, but tempo: every move must be forcing so the defender has no time to escape the mating pattern.
