    At this position white (me) must be better but what can play.
    I played 21.Rd2 but 21.f4 was interesting to me.
    But I was ready to play 21.R:N K:R 22.N:e5+ and maybe 23.N:Bg6 
    I did not want to take the risk of  this  sacrifice because I was ok.What do you thing,it is good this  sacrifice?
    I finally won this game even I make some inaccuracies later

    It is rare to see so many good moves in a single position. I can understand your hesitation. This is Hiarcs 14 analysis. After some seconds it shows preference for the plan of making blacks drop the pawn c6.

    Thank you.
    I did not see the plan to play against the c (and a) pawns (first variation of hiarcs), now I thing it must be the best plan,the black B and Rook maybe come in play but now I have better development and I can play against them and black king may have also problems
     At the game I played Rd2 and R1d1 and even then I had oportunities to have  a better position.
    Finally we reach the 4 against 4 pawns with rooks engame that my pieces were more active,I thing that black should draw this engame but my opponent help me to activate too much my king and i won with 2 pawns up Laughing

    Maybe black is at least much  worst at this position and a man with good technique (like karpov!) may win with white,even we exchange many pieces I had the most active pieces and he did not find the best moves to handle the position.
    [edit]Maybe also Rd2 or Rd3 with Rc1 is best,one rook holding the d file having the choice of doubling rooks .

    Ι think Rc1, followed by Na5 would be a solid plan, while I also liked the doubling of the rooks on -d- file, as Dimis played. Yet, I would have probably gone for the exch. sac with 21.Rxd7+ , 22.Nxe5+ and 23.Nxg6. White seems much better after shattering black's pawns.
