Mate In 3 Puzzle (Rated 1246): Force Mate in 3 — Back Rank Mate
This chess endgame puzzle is a classic forcing attack where king safety matters more than material. White’s pieces are coordinated to exploit a pinned defender and a vulnerable king on the back rank. The key idea is to use a forcing check that drags a defender away, opening a line for the final mating net. In classical chess, these patterns often appear when heavy pieces and a bishop work together against an exposed king.
