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

This puzzle is a classic mating-net idea in a sharp classical chess setting. White’s queen and rook coordinate to restrict the enemy king, while the exposed black king has very few safe squares. The key is that the attack is forcing: every move creates a direct threat, and the defender is dragged into a sequence of checks and captures that only tightens the net. Even though material may be down, the attack wins because king safety matters more than countable pieces here.
