Nimzo Indian Defense Hubner Variation Puzzle (Rated 819): Win With a Fork — Decisive Material Gain

This middlegame puzzle is a classic example of a tactical fork that wins material by exploiting loose pieces and an overloaded defender. White’s queen can create a forcing check while also attacking a vulnerable target, turning a simple capture into a decisive material gain. The key idea is that the opponent’s active pieces are not coordinated well enough to meet every threat at once, so the best move combines forcing play with a clean follow-up.
