Nimzo Indian Defense Romanishin Variation Puzzle (Rated 919): Win Material — Nimzo-Indian Tactics

This middlegame puzzle comes from a Nimzo-Indian structure where piece activity matters more than raw material count. White’s knight is active near the enemy king, but that same activity can become a liability when it is overextended and undefended. The key idea is to look for forcing moves that win material while keeping the initiative. In classical chess, tactical accuracy often turns a temporary imbalance into a decisive advantage.
