Mating Net Puzzle (Rated 1500): Spot a Mating Net — Mate in 4

This puzzle is a classic mating-net example: the attacking side uses piece coordination to trap the king so every escape square is covered. The key idea is not just a direct check, but forcing the defender into a cramped position where natural responses fail. In tactical terms, the attack combines a knight jump, bishop pressure, and rook support to create a decisive net around the king. These patterns often appear in classical chess and sharp middlegame positions.
