Polish Opening Intermediate Puzzle (Rated 1072): Win Material — Tactical Refutation

This Polish Opening puzzle shows a classic tactical refutation in the middlegame, where an active rook invades and creates a fork-like sequence against loose pieces. The key idea is not a mating attack, but a decisive material win by exploiting an undefended piece and the king’s limited coordination. In positions like this, activity matters more than static material, and the side to move can turn a temporary tactical shot into a lasting advantage through simplification.
