Fool's Mate Puzzle (Rated 1500): Mate in 3 — Back Rank Mate
This chess endgame-style puzzle is a classic mating net built around an exposed king and overloaded defenders. White’s active rook and queen coordinate to force the black king into a narrow box, where every defensive resource is tied up by threats on the back rank and nearby pieces. The key idea is not material gain, but forcing moves that limit the king’s escape squares and create a direct checkmating sequence. In classical chess, these patterns often appear when rooks and queens dominate open files.
