French Defense Rubinstein Variation Puzzle (Rated 855): Win with a Crushing Fork — Middlegame Tactic

This puzzle shows a classic middlegame tactical idea: a forcing attack that wins material by exploiting a fork and a discovered check. White’s active queen and knight coordinate against loose black pieces, especially around the king and the f7 square. Black’s bishop and rook placement leaves key defenders overloaded, so one tactical shot can collapse the position. In practical classical chess, these patterns often decide the game long before the endgame.
