Nimzowitsch Defense Defensive Move Intermediate Puzzle (Rated 1091): Win the Queen — Tactical Refutation

This puzzle shows a classic tactical refutation in the middlegame, where the key idea is to exploit a loose queen and the alignment of pieces on the same line. White’s position is built around king safety and active piece placement, while Black’s queen has overextended and can be challenged by a forcing defensive move. The pattern is not about a mating net, but about turning pressure into a decisive material gain through accurate calculation and simplification.
