Sicilian Defense - Moscow and Rossolimo variations

Hi guys, I just wanted to know what the basic ideas are for the following Sicilian (or anti-sicilian?") position. I know the game is generally closed but I just want to know the type of moves that White would want to make in the position.

maybe nd5?

Material is even, But maybe if gameplay would have continued, you could have achieved victory being up a rook.

Chess I like that position, but it seems balanced for me. Can anyone help analyse it? I would prefer to be white tho, but I guess every side has it's good and bad points but I don't really know how to analyse this... Anyway what I wanna know is why did white play  10.nde2 instead of nf3? To let the queen pass after? It seems a good move, but why not bd3?

Thanks for the help. Any more suggestions?
