Dacha Tactics #85 - light bishop turns dark

This is a really cool endgame I came across. To start, white is up a pawn. The imbalance of colors – we have a light bishop vs a knight, which means we are +500 light, -500 dark. If this were just kings and pawns, the game would be over. What gets sticky though, is that we have so much light but very minimal dark. Our king does help on dark, but so does his – and the Kg5 will not move unless it must. So, for now, black has a grip on dark - how can our light bishop make itself useful? Trading off his knight, or dominating the knight, would both be very helpful...
