Black To Move Puzzle (Rated 848): Win Material — Tactical Refutation

This middlegame puzzle is about turning a loose tactical position into a decisive material gain. White’s queen and rook activity look dangerous at first glance, but the key is to notice that several pieces are overloaded and undefended. When a high-value piece is exposed on a vulnerable square, the right response can win material immediately and simplify into a clearly better ending. The lesson is to trust concrete tactics over static impressions.
