10.0-0-0 is the move! (the g3 idea with Bg2 and 0-0 is safe enough but not going to offer much ultimately)
After 10.0-0-0 a6 then there will be a very big an interesting decision between moves like, 11.h4, Kramniks 11.Qf2, 11. Kb1, or even 11.Nb3!? which I think is the Khalifman suggestion.
10.0-0-0 is the main move in this position, no doubt, and seems to be a move everyone here would be happy with (including Smyslov_Fan, I reckon

). In this line I like the Qf2-h4 idea and will look into 11.Qf2 first. 11.h4 (often with Rh3) has been around awhile (and played a lot!). I've seen statements to the effect that Black has no problems dealing with 11.h4, but doubt this is a consensus. 11.Nb3 looks a bit odd (idea is to avoid exchanges?); I'm intrigued that this might be Khalifman's suggestion. If so, I wonder if anyone can tell me why Khalifman suggests it.
Although it hasn't garnered much enthusiasm here thus far, I still haven't eliminated 10.g3. White has a couple of nice wins with this move.
As for 10.Be2, I liked it initially but now am not so fond of it on account of the 10...Nxe5 line, but could be convinced otherwise if anyone can find a way to make this line look attractive for White (an alternative point of discussion is: how many beers does it take to make this line attractive?

).
Right now I'm weighing 10.g3 vs. 10.0-0-0 a6 11.Qf2. If I like the second line better, this is probably the way I will go. If 10.g3 seems better, then I will compare it with other 10.0-0-0 lines and then decide.
I don't think any of White's options discussed so far are clearly superior/inferior (except that 10.Be2 looks drawish in the 10...Nxe5 line). All reasonable choices; mainly a matter of personal preference at this point.
