Polish Defense Fork Puzzle (Rated 969): Win Material — Fork Tactic

This middlegame puzzle is a classic example of a tactical refutation based on king safety and a fork. Black’s attack works because White’s king is exposed and a key central piece is overworked. Once the first forcing move lands, White is pulled into a sequence of captures that cannot be avoided without losing material. In practical classical chess, these patterns often appear when a pinned or overloaded piece becomes the target of a forcing combination.
