Tarrasch Defense Rubinstein System Puzzle (Rated 1514): Win Material — Tactical Refutation

This middlegame puzzle shows how a single tactical shot can convert a small edge into a decisive material advantage. White’s queen activity creates pressure near the black king, but Black can exploit the exposed alignment of pieces and the overloaded defender around the king zone. The key idea is not a flashy attack for its own sake, but a forcing sequence that wins material while keeping the initiative. In classical chess, these tactical refutations often arise when one side’s king is still in the center.
