Sicilian Defense Mengarini Variation Puzzle (Rated 1383): Win Material — Tactical Refutation
This middlegame puzzle is a classic example of tactical refutation: one active queen move exposes an overloaded defender and wins material by force. White’s queen and knight are tied to key defensive duties, while Black’s bishop and queen coordinate against the same cluster of pieces. The position rewards accurate calculation over general plans, because the best continuation immediately turns a seemingly active white setup into a decisive material gain for Black.
