Magnus' mighty rooks

7/3/2010 – In the Kings Tournament Magnus Carlsen was once more very convincing, winning majestically with a lead of two points. The position Carlsen- Radjabov is taken from their seventh round game. In this ending, Black, whose move it is, has to be very careful about the safety of his king, because Carlsen's rooks occupy threatening posts. At the same time the final black pawn is under attack and the question is whether it should be defended with 45...Rg4 or 45...Ra2. Which of these two moves would you recommend Black to play?
