Dom, 

What was Dashibalov's rating? Your line 

C)

15.Nxa5(?) seems like a dream for Black. It hands Black an extra move and extra attacking squares on the Q-side and removes one more piece from any potential kingside attack.  (Granted, there are only a few variations in which the Nb3 does indeed attack.) 

From what Ostap has been saying, there's little chance he will play that anyway.

I can't blame you Dom you missed it, but I already have managed to refute line A with 22.Rf1 (indeed 22.Qh6 is less precise, though the final position might also be good for White) a5 23.f5 exf5 24.gxf5 Qxe5 25.fxg6 hxg6 26.Re1 Qh8 27.Re7 wins. At the moment I think Black must play either 16.Qe1 Qh4 or 16.Qf2 Bxc3.

I'm inclined to agree with this as well.  Athough I haven't looked at 15.Bd4 Nxb3+ deeply enough to be absolutely sure, it seems to me that 15.Rg3 is the right way to go - at least based on continuations examined so far.

I don't think that 15.Bd4 is actually a bad move, however - just a bit slower, and probably less certain, route to an advantage for White.

I think it was Dom, who suggested 15.Bd4 Nxb3+, also several moons ago.  

well I was away on holidays for a while and now just checked this thread to see how things were going....

firstly I am interested in the decision of 14...Na5 rather that 14...Rc8 - I still like that move for Black  

Now after 14...Na5 (which I also thought was interesting) as I see it from my brief look at the posts we are trying to follow some computer analysis after 15.Rg1. Instead I suggest we stick with the human touch - 15.Bd4! fulfills the positional requirements and the attack will still be coming. I posted some analysis on this many moons ago.... perhaps improvements have been forthcoming in the meantime, apologies as I have to catch up and read all the posts  

Right now I'm analyzing (15.Rg3 Nc4) 16.Qe1 lines to see if White has a good continuation vs. 16...Qh4 and 16...Re8.  I think White's prospects look quite good in both cases, but there are still details to work out before I can make a reasonably confident assessment.

Based on what MNb is posting, 16.Qf2 lines are also looking promising - although I imagine there are still details to be worked out here as well.

If White has no problems proceeding with the typical attack after 16.Qf2 Bxc3 17.bxc3 then I can see no drawback to playing Qf2 instead of Qe1.  On the other hand, if White has no problems with 16.Qe1 Qh4 and 16.Qe1 Re8 lines (which is how it's looking to me so far) then I see no drawback to sticking with Qe1.

In the end, it may just be a toss-up.

memers, 

Thanks for the vote of confidence!  If I have to kiss the game good bye, then I have to go all the way back to 11.Nb3.  Maybe Watson's 11...b6 is indeed best, but I wanted to test out the "main" variation.  If this position is a bust, then I think 11...Bb4 is a bust too.

If 11...Bb4 is a bust, then congratulations to Ostap and company for proving it (at least to my satisfaction).

However, I still have some hope despite the dire weaknesses on the kingside.  We'll see what happens.  I'm not making any excuses when I say I lost some key analysis a few days ago, but I will have to recreate some pretty difficult and precise defensive moves.  Oh well, I guess that's the price of not backing things up.

Cheers!

PS:  Will you be at the Colorado Open, memers?

Hello,

1.OSB, I apologize for the witty?? remark. I was just making a comment on the origin of your "P" name and I find out on a earlier post between you and SF. Nothing vulgar or insinuating. I think the position is won/advantage for White after 15.Rg3 Nc4,  in fact, after 15. Rg3, IMHO. I also, posted the wrong variation on 14...a5 15.Rg3 Bxc3 16.Qxc3 Nb4 was the line I was thinking about. The other line just shows the inherent sac that is there after 15.Rg3.

2.MNB, 16.Qf2 Bxc3 should be better than 16...Re8. Like other posts, I threw a curve ball.

3.Finally,SF, unless OSB is gracious enough to play 15.Rg3 Nc4 16.Rh3 with implied draw offer, you should kiss your game goodbye and chalk it up as a bad experiment.

Cheers
