Hector Rossetto (White) Puzzle: Checkmate — Mate in 4

This middlegame puzzle demonstrates how active rooks can overpower a materially superior position. White has an extra queen, but Black’s pieces are better coordinated around the exposed king. The key strategic idea is to prioritize forcing checks over material concerns, using rook activity to restrict escape squares and maintain momentum. This is a classic mating-net lesson: when the enemy king is boxed in, coordinated heavy pieces can deliver checkmate before the opponent has time to exploit a material advantage.
