Thanks for the game citation.  Nunn also gives White a += after the exchange on c6.

The practical results suggest that White's advantage may be even larger, but when I look at the position I don't see why.

I glanced through the game you gave, and it went the way I would expect.  Did White have any major improvement in the opening phase?


By the way, this was a rapid game, too.

(Fritz suggests that Black drifted a bit and White missed a winning shot with 33.Re5! instead of 33.Rgh1. But Black had plenty of resources before then.)

I've always seen it with one "s".  As for how he fared (rapid game though it was), see below.

A typical book citation for 12...Bd7 is ECO's 13. Nxc6 Bxc6 14. Bxc6+ bc 15. Qd4 +=  Beliavsky-Ghinda 1980.  Drazen Marovic criticized Ghinda's 15...Qa5+ 16. c3 c5, suggesting 15...Qxd4 16. Bxd4 f6.

Thx, Kyle!

I've seen a key game that followed 12...Bd7. Kevin Spraggett won fairly convincingly over Galego(2530) in 2007, but I'm not sure it was down to the opening. 

Do you have any more info on 12...Bd7 and how Movsessian faired? (Btw, is this really how he spells his name using the Latin alphabet?)

Incidentally, the other day, Movsesian played 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. g4 h6 7. h4 Nc6 8. Rg1 d5 9. exd5 Nxd5 10. Nxd5 Qxd5 11. Bg2 Qe5+ 12. Be3 Bd7 (eschewing 12...Nb4, which has been recommended by some sources).

Just reiterating the last question...

Markovich, how did your correspondence games in this line go?

My own experience is that I should have lost two CC games but ended up winning because in both cases my opponent chickened out of the main lines. I'll post the games later.

Thanks for that very interesting reply.  For the time being I will only address (1).  Quoting Palliser from an update last year:

"An important alternative is 9. exd5 Nxd5 10. Nxd5 exd5 11. Be3 Be7 12. Qd2! Bxh4 13. O-O-O , which has long been known to give White promising play for his pawn a view not disturbed by the recent game Gashimov-Riff, European Club Cup, Kallithea 2008: 13... Bf6 14. Bb5 O-O 15. Bxc6 bxc6 16. g5!?"

...and Black went on to defeat.  So I think that this, more than 9.Bb5, challenges (1).


I've been messing around with this line. My question: is 13 ... Bf6 necessary? Perhaps 13. ... O-O is an improvement. 14. Bb5 can be answered with Nxd4. 14. Nf5 does seem critical. Still early days though.

Anyway, Markovich, how are your corr. games coming along?

Well, hopefully that's not enough of a sample to draw any definitive conclusions. 

Indeed, you might take comfort that 11.Be2 and 11.Qd2 are more popular than 11.Rg3, despite Gavrikov's endorsement. 

But we'll see.

It seems an interesting question whether this 11...a6 12. Nxc6 stuff is preferable from Black's point of view to the somewhat similar Richter-Rauzer with 7...a6 8. 0-0-0 h6 9. Nxc6 bc 10. Bf4 d5, which is considered difficult for Black these days.  Incidentally van der Wiel-Winants was given as slightly better for White by Epishin in a Russian opening encyclopedia, and as unclear in Informant/ECO.


The position after 12.Nxc6 bxc6 13.Qf3 Rb8 14.0-0-0 Qb6 15.b3 Nh5 16.Rg1 comes up 9 times in my data base, with White scoring 100%, no less!  In five of those games, Black played 16...g6, which I consider to be the best move.  White also won all three games where he played 14.b3 instead of 14.0-0-0.  Still the position looks quite interesting to me, and I'm not sure if Black is really all that badly off.  In fact it seems to me that he has some chances.

Among the five games with 16...g6, there is just one played at a very high level, Van Wely's.  

I'll find out soon enough, anyway, since I'm walking into Black's side of this in three CC games against even opposition.  I have something new prepared against 17.Kb1.  We'll see if that comes up, and if it does, if my idea is any good.

In any case, as Black I have reached the position after 9...Nxh5 in a CC game, so I will soon find a few things out for myself.  I have two other games in early progress, which I expect may go the same way.

Is 6..h6 7.h4 Nc6 8.Rg1 h5 9.gxh5 Nxh5 10.Bg5 Nf6 11.Rg3 a6 12.Nxc6 bxc6 13.Qf3 really all that scary for Black?  

Logical seems 13..Rb8 14.0-0-0 Qb6 15.b3 Nh5 16.Rg1 g6.  Van der Wiel (in an old game vs Winants) now played 17.Bc4, which is probably inaccurate, but even after Gavrikov's suugested improvement of 17.Bh3 or 17.Kb1, the position seems OK to me.  

 


These 11...a6 ideas produce what seems to me to be dynamic equality.  Or at any rate, I don't know enough about chess to claim that one side or the other is better.  White has his activity, Black has all those central pawns and the half-open b-file.  I am less enamored of the 11...Be7 ideas, which seem upon brief inspection more definitely to favor White.

Also, if Black doesn't like this line, he can duck out with 11..Be7 12.Qd2 a6 (Pritchett) or 11..Be7 12.Qd2 Nxd4 (Adorjan).  I think White keeps an edge in both these lines, but it shouldn't be the end of the world.

My latest thinking is that line 2 (see original post) is perhaps Black's best if he has much intention of winning.  Whatever its ultimate theoretical merit, I think it would be easy for a well-informed Black to outplay someone in this line.



9.gxh5 Nxh5 10.Bg5 Nf6 11.Rg3 a6 12.Nxc6 bxc6 13.Qf3 seems to be quite the headache.

@Markovich,
your reply #17 with the idea of 12... Qh2 (after 6. g4 h6 7. Rg1 Nc6 8. h4 d5 9. exd5 Nxd5 10. Nxd5 exd5 11. Be3 Qxh4 12. Bb5) didn't slip away unnoticed. I like it quite a lot because it helps to bring back the queen into game. This move also disturbs the white coordination a little bit.

Incidentally, this reminds me of a similar motif (well, the same move) in another line. A recent corr game (John Pugh-Arno Nickel, Simon Webb mem email, 2007) was 6. g4 h6 7. h4 Nc6 8. Rg1 d5 9. exd5 Nxd5 10. Nxd5 Qxd5 11. Bg2 Qe5+ 12. Be3 Qh2 13. Nf3 Qc7 14. c3 e5 15. Nd2 Be6 16. Qa4 Be7 17. O-O-O O-O and 1/2-1/2 after 32 moves. This shows a possible way to equality for Black in the line with 10... Qxd5 (a line which is not scoring so well, as remarked in this threat before).
