Dacha Tactics #15 - lighthouse dacha!

Very complex! Where to start looking? The colors, naturally. Black has more space and pressure on White's king. As for the color money, the imbalance is Knight vs Dark bishop. Which means we are behind on dark, but ahead on light. Moves like Nf3 spring to mind -- but don't work just yet. Our light bishop may look sleeping, but it isn't. How to show off our light edge? Remove the last vestige of White's light protection!
