Nimzo Indian Defense Classical Variation Puzzle (Rated 1038): Win a Fork — Decisive Material Gain

This puzzle comes from the Nimzo-Indian Defense, Classical Variation, where tactical awareness matters as much as opening knowledge. White’s queen can jump into an active checking square, forcing Black’s king and pieces into awkward coordination. The key idea is that the check is not just a forcing move; it also exposes a loose piece and creates a direct win of material. In classical chess, these short tactical shots often punish a pinned or overloaded defender.
