Four Knights Game Scotch Variation Accepted Mate In 3 Puzzle (Rated 1083): Mate in 3 — Re1+ Pattern

This puzzle is a classic middlegame mating net from the Four Knights Game, where active rook play and piece coordination overwhelm the exposed king. White’s rook activity on the open file is the key strategic clue, and the position rewards forcing moves that limit the defender’s options. Even though material is down, the attack is stronger because the black king is stuck in the center and the pieces around it are poorly coordinated.
