Benoni Defense Fianchetto Variation Puzzle (Rated 1286): Win Material — Tactical Refutation

This middlegame puzzle is a classic example of a tactical refutation: one side’s active pieces and king pressure force a sequence that wins material decisively. The key idea is to notice how the queen and knight coordinate against loose pieces and weakened king shelter. White’s extra material is not enough when the king is exposed and key defenders are overloaded. In classical chess, these positions often reward forcing moves that create immediate threats and leave the opponent no useful defense.
