Benko Gambit Accepted Fianchetto Variation Puzzle (Rated 1441): Win Material — Decisive Queen Sacrifice

This middlegame puzzle is a classic example of a forcing tactical sequence that wins material by exploiting loose pieces and a vulnerable back rank. White’s active queen and bishop coordinate against Black’s queen, rook, and knight, creating a position where one tactical shot opens the way for a clean conversion. The key idea is not a quiet improvement, but a forcing line that removes the defender and leaves Black unable to keep everything protected.
