Mate In 3 Puzzle (Rated 1318): Find Mate in 3 — Triangle Mate
This chess endgame puzzle is a classic example of a forcing attack where king safety matters more than material. White’s king is exposed, and Black’s heavy pieces coordinate to create a mating net with checks that limit escape squares. The key idea is a discovered attack: one piece is sacrificed or moved to open a line for another attacker. In practical classical chess, these patterns often decide games instantly when the king is boxed in.
