Dacha Tactics #90 - Dark money taken to the bank.

From a recent blitz game of mine vs a young IM from Moldova. I'm feeling pretty good here with the white king stranded in the center. However, our dark bishop is attacked, and if it moves, a queen trade will occur, and our attack will all but vanish. So, we go straight to the classic query – What's the color money? Well, it's a knight vs his light bishop, which means we are ahead on dark. On top of that, he has dark weaknesses on the kingside and possibly queenside too....
