Moscow Variation Puzzle (Rated 854): Win Material — Tactical Refutation
This middlegame puzzle is about spotting a forcing tactical refutation when the opponent’s king is still vulnerable and key pieces are lined up badly. White’s queen and rook are active, but Black has a hidden counterstrike that wins material by exploiting the loose queen and the exposed back rank. The idea is not a flashy mating net; it is a clean sequence that removes the defender, simplifies the position, and converts activity into a decisive material edge.
