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
The sac is interesting but my first choice would be to play Rc1 with the idea of Na5 beating on c6. There's still plenty of pieces on the board and black's king is not safe. Black has to untangle his pieces and your threats develop quickly. I'm sure you win at least a pawn. Black may have some type of defense but it would be super hard and your moves are simple to find.
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.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.
