Queens Indian Defense Fianchetto Traditional Puzzle (Rated 1279): Win Material — Crushing Middlegame Tactic

This middlegame puzzle is a classic example of exploiting an overloaded defender. White’s queen is doing too much at once, guarding a key rook and a vulnerable knight while also trying to keep the position together. Black can force a sequence that removes the defender, simplifies the tension on the c-file, and then wins material with a follow-up strike. The idea is not a flashy attack on the king, but a precise tactical refutation that turns piece coordination into a liability.
