How to exploit the position
Clear strategic command for White: Black's b4 bishop is displaced and White's d5 knight reigns supreme.
- Maintain the knight on the d5 bastion, forcing Black into retreats or surrendering the bishop pair.
- Solidify the center with d2-d3 and prepare queenside pawn expansion with a3 and b4.
- Pressure Black's c5 bishop by opening the position with f2-f4 or b2-b4.
- Dominate the middlegame through vastly superior minor piece coordination.
