Nimzo Indian Defense Ragozin Defense Puzzle (Rated 1489): Win Material — Discovered Attack

This middlegame puzzle shows a classic discovered attack idea inside a Nimzo-Indian Defense structure. White’s bishop sacrifice on h7 draws the king away and clears the line for a direct tactical strike on the back rank and queen. The key point is that the attack is not about a long mating net here, but about forcing the king into a vulnerable square while the queen becomes exposed. It is a sharp example of how kingside pressure can convert into decisive material gain.
