Nimzo Indian Defense Puzzle (Rated 1086): Win with a Fork — Nimzo-Indian Theory
This middlegame puzzle comes from the Nimzo-Indian Defense and shows how a forcing tactical sequence can turn a small edge into a decisive one. Black’s active pieces create pressure against White’s center and king safety, while White’s material lead is undermined by loose coordination. The key idea is to use a check to gain tempo, force a defensive response, and then continue with a tactical strike that wins material or improves the attack. It is a classic example of how activity can outweigh static material.
