Mate In 2 Puzzle (Rated 1149): Mate in 2 — Triangle Mate

This chess endgame puzzle is a classic example of a forcing mating net where king safety matters more than material. White’s heavy pieces are already active and coordinated around the enemy king, so the key is to use a forcing check that limits escape squares and drives the king into a tighter box. In classical chess, these patterns often appear when the defender’s back rank and nearby squares are overloaded or weakened.
