Mate In 2 Puzzle (Rated 1357): Spot Triangle Mate — Mate in 2

This puzzle is a classic middlegame mating net where king safety matters more than material. White’s pieces coordinate to create a forced check that drives the king onto a vulnerable square, where the final attack lands with a queen supported by a rook and minor-piece pressure. The key idea is not a random sacrifice, but a forcing sequence that uses check, tempo, and restricted king mobility. In classical chess, these patterns often appear when the enemy king is boxed in by its own pieces and pawns.
