Russian Game Karklins Martinovsky Variation Puzzle (Rated 941): Win Material — Crushing Fork Tactic
This middlegame puzzle centers on a classic crushing fork: one active queen move creates a forcing check while also targeting key pieces. The position rewards tactical refutation over slow play because White’s knight is overloaded and Black’s queen activity is already dominating the board. Once the forcing check lands, the defender is pushed into a passive reply, and Black can convert by winning a major piece. The idea is not a mating attack, but a clean sequence that turns initiative into decisive material gain.
