Nimzo Indian Defense Rubinstein System Puzzle (Rated 1436): Win Material — Nimzo-Indian Tactics

This middlegame puzzle comes from a Nimzo-Indian structure where White’s pieces are active and the black knight on c4 is a major target. The key idea is to improve the queen to a square that pressures the center and the queenside while keeping an eye on tactical resources around Black’s king. White is not looking for a direct attack on the king, but for a clean winning combination that exploits loose pieces, especially the advanced knight and the vulnerable coordination of Black’s queenside pawns and bishop.
