Nimzo Indian Defense Three Knights Variation Puzzle (Rated 1053): Win Material — Tactical Refutation
This middlegame puzzle is about spotting a forcing tactical refutation when pieces are overloaded and king safety is shaky. Black’s active queen and bishop create direct pressure, while White’s rook and queen are both vulnerable to tactical hits. The key idea is to recognize when a seemingly active piece is actually hanging or pinned to a more valuable target. In positions like this, a decisive material gain often comes from forcing moves that win the exchange and then convert the remaining advantage.
