Clearing some space for the bishops before White manages to consolidate by Nd6, Kg2-f3, etc.
After 2.exf6 gxf6 Black obtains a potential passed pawn, and White loses his outpost on d6.
With ideas like 8...Bf3, winning the battle for the d-file. By now the range of the bishop pair is rather worrying for White, whereas the knights are lacking protected squares. Black later won.
Intending ...b5-b4 to weaken the a1-h8 diagonal for the bishop, in particular the d4-square.
Now the bishop is doing a great job in helping his colleague to put pressure on g2.
