Queens Gambit Declined Capablanca Variation Puzzle (Rated 935): Win Material — Decisive Queen Fork

This middlegame puzzle comes from a Queen's Gambit Declined structure where king safety outweighs raw material. White’s queen is ideally placed to create a forcing tactical sequence against the exposed black king and loose defenders. The key idea is a decisive queen fork: one check forces the king into a worse square, and the follow-up wins a major piece with tempo. In classical chess, these tactical shots often appear when development is uneven and the enemy king is still in the center.
