Nimzo Indian Defense Fischer Variation Puzzle (Rated 1603): Exploit Exposed King — Decisive Material Gain
This middlegame puzzle shows how a king stuck in the center can become a tactical target even when material is already imbalanced. White’s pieces are active, the bishop pair is powerful, and the open lines around Black’s king create a forcing attack. The key idea is to use a forcing capture to drag a pawn away from the king’s shelter, then continue with checks that win material and keep the king exposed. It’s a classic example of converting activity into a decisive tactical refutation.
