Dacha Tactics #104 - Knight got dark bling bling

Here's a cool position I saw from a blitz game with the legendary Hikaru Nakamura manning the white pieces. At first glance, we notice the d5 pawn is loose, but the knight on c5 is somewhat loose, and the b3 pawn is not fully secure either. What's the color money? Well, it's a knight vs his light bishop, meaning we are behind on light but ahead on dark. The knight is perched on dark, and the black queen and rooks are on dark – all this could be in our favor. Find the unexpected dark blow! Do note that sometimes a loud dacha move will not lead to an immediate win but rather a long-term advantage...
