Cappelle La Grande 2013 Rd3-GM Hansen E(CAN)

Hansen had to weather a storm in the middlegame before taking over in a complex R-R ending.

Todorcevic,M (2419) - Hansen,E (2557) 
French Winawer 4.Bd2[C15]
Cappelle La Grande(3), 26.02.2013

Position 1

The position is complicated and it is not clear who has the safer king and who is attacking who. Black's king is hiding behind a wall of pawns while Kb2 is exposed on the b-file. 

What do you suggest for white?
