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).

However 11...Qxh4 is a possible improvement on Gashimov - Riff, for instance 12.Qf3 Nxd4 13.Bxd4 Qe2+ 14.Be2 Qb4+ 15.Bc3 Qc5 16.0-0-0 Be6.  Or 12.Nb5 Qe7 13.Qxd5 Be6 14.Qe4 a6.  Both the lines given have been played.


Maybe 12.Qe2 Be7 13.0-0-0 0-0 14.Nf3 Qf6 (14..Bxg4!?) 15.g5 hxg5 16.Bxg5 Qf5  17.Bxe7 Re8 18.Qd2 Rxe7 19.Rg3 Ne5 20.Nxe5 Qxe5 as played in Timmerman-Van Wely, Ned Ch 1993.  Here, Timmerman chose 21.Re3 and traded rooks, but perhaps 21.Bd3 with the idea of doubling on the g-file and/or Qh6.

I promote this thread just because I think nobody noticed my idea, which may be important.

Regarding Gashimov-Riff, I've had the impression that 10...Qxd5 is the main move there.

In my data base, it's played slightly more than 10...exd5, but it scores significantly worse.  White is 71% after 11.Bg2 in 37 games. Looking at the position, Black seems to be falling dangerously behind in activity.  10...exd5 looks much more like chess to me.

However 11...Qxh4 is a possible improvement on Gashimov - Riff, for instance 12.Qf3 Nxd4 13.Bxd4 Qe2+ 14.Be2 Qb4+ 15.Bc3 Qc5 16.0-0-0 Be6.  Or 12.Nb5 Qe7 13.Qxd5 Be6 14.Qe4 a6.  Both the lines given have been played.


Hmm.  A question could be, after 11...Qxh4 12. Bb5, does Black have anything better than 12...Bd7, which would transpose to a line which last I was aware seemed a little better for White, as in a game Ashley-Salov.    


You may be right.  Ashley - Salov was drawn, of course, and I think that Black might have improved by playing 18...Qe4 instead of 18...a6.  I am sorry, I don't seem to be able to get the whole game into the paste buffer, but 12...Bd7 13.Qe2 Nxd4 14.Bxd4+ Qe7 15.Bxd7 Kxd7 16.Ke3 Rd8 17.O-O-O Kc8 18.Qf3.


Lately I also noticed 12...Qh2, which may be adequate.

I wonder what (if anything) Kasparov had to say regarding Markovich's line B in his Karpov book of last year.  In their first match Kasparov met 9. gh Nxh5 10. Bg5 with 10...Nf6, which seems to be regarded more highly than 10...Qb6 by most sources I've seen.

After 7..Be7 8.Qf3, if Black isn't happy with 8..Nc6, he can play 8..h5!?

Yeah, that's the line recommended in Experts vs the Sicilian.  I looked at it and it didn't seem utterly terrifying.

@Zatara: Thanks, I'll look at that.

Regarding (3), one thing I've come across which seems += and annoying for Black (and not mentioned/skirted over in most sources I've seen) is the way White played in Rasik-Jansa 1992:  9.exd5 Nxd5 10.Nxd5 Qxd5 (alleged to be better than 10...ed by Yermolinsky and others) 11.Bg2 Qc4 12.Be3 Bd7 13.Qe2 Qxe2+ 14.Kxe2 Nc6 15.Nxc6 Bxc6 16.Bxc6+ bxc6 17.Bd4 0-0 18.h5.  


Yes, I agree that putting the Bishop on the long diagonal is more challenging than the Bb5 check.  But I don't see where Black has much to worry about in this line.  Even if you consider the position after 17.Bd4 to be +/=, it doesn't seem to mean that much, as it's likely to be a draw in any event.  E.g., 17..f6 18.h5 Kf7 19.Rad1 Rhd8 20.Rd3 e5 as in Lamaroux-A.Sokolov, Cannes Op 1998.

BTW, if Black wants to try for more in this line, he has the risky 12..Qb4+.  I tried this once, and after something like 13.c3 Qxb2 14.Qc1 Qxc1 15.Rxc1 a6 16.Rb1 Nd7 thought I was going to get squashed, but, if memory serves, it worked out ok in the end.   Wink

So I am interested in the Scheveningen in its pure form, currently being upheld by Movsesian.  Naturally, I'm concerned about the Keres Attack.  In reply to 6.g4 I am only willing to consider 6...h6, also Movsesian's choice, after which the most critical is 7.h4.  

Black has three principal methods of defending:

(1) 7...Nc6 8.Rg1 d5

(2) 7...Nc6 8.Rg1 h5

(3) 7...Be7 8.Rg1 d5

Well, I've looked at them all at some length, and I'll be hanged if I can find anything for Black that doesn't leave him in notable difficulty. The biggest problem is king safety: White's king is relatively safe after 0-0-0, while Black's is never safe anywhere.  For instance, in (3) the critical continuation is 9.exd5 Nxd5 10.Bb5+! Kf8 11.Nxd5 Qxd5 and not only is Black's king under the weather, but his KR is out of the game for a long time.

I understand that this merely restates a conclusion already reached by many other people. But then why the heck is Movsesian upholding the Scheveningen, and why the heck isn't anyone challenging him with 7.h4?  What I'm saying is, I've tried and failed to guess what he has up his sleeve.


Sometimes the "fear of improvement syndrome" discourages opponents from taking on a specialist - it often feels like you are walking into a trap or at least giving him home advantage.

For instance it takes a brave man to play the Keres against Nisipeanu, since you are likely to have to face the very sharp and still unclear 6...e5!?, with Sveshnikov themes.

That doesn't solve Black's problem though. There was once a time when the Scheveningen was considerably less theoretical than the Najdorf, and could be played based on an understanding of a few themes and move order issues. No longer: 6 g4 is just one of many Scheveningen labyrinths, where extensive and precise knowledge is required - and even then there is no clear path to an even game.

In practice, specialists (even Movsesian) tend to vary their move order. 1 e4 c5 2 Nf3 e6 3 d4 exd4 4 Nxd4 Nc6 5 Nc3 d6 is the most popular alternative for Scheveningen players (those who are unwilling to use the Najdorf move order) when 6 g4 is still pretty strong but requires less (and less precise) theoretical knowledge for Black to handle it.

Finally, if you know you are going to be playing a sharp player who studies theory and relies on the Keres Attack against the Scheveningen, it might pay to play some more nebulous ...e6 system such as the Kan, or one of those ...Qb6 systems - or even avoid the Sicilian altogether and try to bore them to death with something really solid!  Wink

Markovich's (3) is Pritchett's recommendation for Black in his Starting Out book.  Might be the way to go as Black.

Regarding Gashimov-Riff, I've had the impression that 10...Qxd5 is the main move there.

In my data base, it's played slightly more than 10...exd5, but it scores significantly worse.  White is 71% after 11.Bg2 in 37 games. Looking at the position, Black seems to be falling dangerously behind in activity.  10...exd5 looks much more like chess to me.

However 11...Qxh4 is a possible improvement on Gashimov - Riff, for instance 12.Qf3 Nxd4 13.Bxd4 Qe2+ 14.Be2 Qb4+ 15.Bc3 Qc5 16.0-0-0 Be6.  Or 12.Nb5 Qe7 13.Qxd5 Be6 14.Qe4 a6.  Both the lines given have been played.


Hmm.  A question could be, after 11...Qxh4 12. Bb5, does Black have anything better than 12...Bd7, which would transpose to a line which last I was aware seemed a little better for White, as in a game Ashley-Salov.

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).

Interesting topic. I've played the Keres from both sides, though I did better (and felt better) with the white side. Nevertheless, theoretically speaking it does not look too grim for Black.

ad (1): In this line Black is ok after 7... Nc6 8.Rg1 d5 9.Bb5 Bd7 10.exd5 Nxd5 11.Nxd5 exd5 12.Be3 Be7 13.Qd2 0-0 14.Bxc6 bxc6 15.0-0-0 Rb8 (Volokitin,Andrei - Movsesian,Sergei, RUS-chT Dagomys, 2008). This line even sets a nice "trap": 14.Nf5 d4! (Timmerman,Gert Jan - Andersson,Ulf corr 1994) This would be my favorite line if I played it again with Black.

ad (2): I'm lost a bit in the complications of this line which always has been one of the main lines. Nunn (Beating the Sicilian, three editions) always came up with new ideas/tries for a white advantage only to rewrite in the next edition. And Gavrikov in Experts vs. Sicilian has some other recommendations again. So the authors have not fould the final refutation, I'd say. – Movsesian went for the sideline 10... Qb6 recently which looks like a reasonable choice. His game was 7... Nc6 8. Rg1 h5 9. gxh5 Nxh5 10. Bg5 Qb6 11. Nb3 a6 (Kokarev-Movsesian 2007) and here 12. Be2 is said to be the real test. After g6 13. Qd2 Bd7 14. Rg2 Qc7 15. O-O-O b5 16. a3 Ne5 17. Qd4 White won in two games but after Qa7N Black should hold.

ad (3): Yermolinski (Road to chess improvement) was sceptical about this early bishop check and he even gave it as 9. Bb5+(?!). The line he discussed along with this move went 7... Be7 8. Rg1 d5 9. Bb5+ Kf8 10. exd5 Nxd5 11. Nxd5 Qxd5 12. Be3 Nc6 13. Nxc6 bxc6 and Queens off and White has nothing.

Your comments welcome.
