Sicilian Dragon

How do you evaluate this position?

Deep Rybka says 0.00

Isn't this really bad for black? He's two pawns behind because he lost his rook and only took a bishop. I just played a game where I was in this happy situation. My book suggests trying to exchange pieces when you're ahead, so I did, and it worked!

So I'd be thinking of NxN, followed by a serious attempt to swap bishops, then swap Queens and then R & R *should* be able to handle R & B. But maybe I'm missing something...

My book also recommends a "pawn storm", to attack the K castled on the opposite side.  

But this is the main line of the opening.

Black is down an exchange, true, but he has a monster bishop on g7 whose counterpart has vanished, the b file offers attacking possibilities, and White is a bit late in development. I do not know whether it's enough or too much or too few compensation, but it's certainly better than "down an exchange".

Now black has the initiative i think

In this particular variation, white's dark-square bishop is worth at least a rook, because black's g7 (or "dragon") bishop is a monster.  White's knight on c3 is a major focal point and there are many themes that involve black sacrificing pieces on c3 to open up the diagonal/b-file.  As white you should be aiming to force a trade of the dark squared bishops and then create a king-side pawn storm.  

Any one wanna play a takeback game with me in this variation?

very sharp line

There was a discussion around here. Too analize the black position after d5. I think that these move is bad, and blacks can almost to match the game. If we play the system Veresov - Dubinin: Bd7, Rc8 and Qa5 there is much too discuss
