Nimzo Indian Defense Romanishin Variation Puzzle (Rated 893): Crush Kingside Attack — Bishop Sacrifice
This middlegame puzzle shows how a direct kingside attack can override static factors like space and material balance. White’s pieces are aimed at the enemy king, and the key idea is to remove the defender that protects the dark squares around the king. Once that shield is broken, the queen can join the attack with forcing checks and a decisive tactical follow-up. The position rewards active piece placement and a clear sense of timing.
