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.

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.

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.
