Petrov's Defense Puzzle (Rated 983): Win Material — Tactical Refutation

This Petrov’s Defense puzzle is a classic middlegame tactical refutation where king safety and loose pieces decide everything. White’s queen and bishop are active against the black kingside, while Black’s attacking pieces are overextended and vulnerable to capture. The key idea is to exploit hanging pieces, pins, and skewers to force a sequence that wins material and leaves White with a decisive advantage. In practical classical chess, these patterns often appear when one side’s attack is built on piece coordination rather than sound support.
