Mating Net Puzzle (Rated 1500): Spot a Mating Net — Mate in 3

This puzzle is a classic mating net: the attacking side uses active rooks and queen coordination to trap the king with no safe squares and no useful captures. The key idea is that a forcing rook move creates multiple threats at once, including a skewer and a direct checkmate threat. In positions like this, king safety matters more than material, and even a seemingly strong defensive piece can become overloaded when the final net is tightened.
