Nimzowitsch Defense Beginner Puzzle (Rated 1242): Win Material — Tactical Refutation

This puzzle comes from the Nimzowitsch Defense and shows a sharp middlegame where king safety outweighs material. Black’s pieces are aimed directly at the white king, and the key idea is a forcing queen move that creates a tactical refutation. The position is a classic example of how an exposed king and loose pieces can turn a small edge into a decisive material gain, even when the board looks balanced at first glance.
