Nimzo Larsen Attack Intermediate Puzzle (Rated 1412): Win Material — Discovered Attack

This opening puzzle shows a classic discovered attack: one piece moves away and suddenly opens a stronger line for another piece. In the Nimzo-Larsen Attack, that kind of tactical alertness can turn a quiet-looking middlegame into a decisive material win. The key idea is to notice when a defended piece is overloaded or when a hidden line to a valuable target becomes available after a forcing capture. Strong players use this pattern to punish loose coordination.
