Mate In 4 Puzzle (Rated 1167): Force Mate in 4 — King Safety
This chess endgame puzzle is a classic example of a forcing king-safety attack that turns a material deficit into a mating net. White’s pieces are coordinated to exploit the exposed black king, and the key idea is to use checks that limit escape squares while driving the king into a tighter box. In classical chess, these patterns often appear when active rooks and queens work together against weakened pawn cover and passive defenders.
