Petrov's Defense Modern Attack Puzzle (Rated 972): Win Material — Decisive Tactical Gain

In positions like this, the side to move should always check for forcing moves that win the queen, exploit hanging pieces, or create a sequence where the opponent’s best defense still leaves them down material. The key idea is to value forcing play over passive consolidation.
