Nimzowitsch Defense Intermediate Puzzle (Rated 1320): Win Material — Intermezzo Refutation

This puzzle shows a classic intermezzo idea in the middlegame: instead of recapturing immediately, White uses a forcing check to win the most valuable target first. The position is built around a tactical refutation of Black’s active knight and loose coordination. Once the forcing sequence starts, Black’s king and rook become vulnerable to simplification, and White’s follow-up gains material cleanly. It is a strong example of how classical chess tactics often punish overextended pieces.
