Avrukh considers this line to be "practically refuted" thanks to 13. Rc1 Nc5 14. Qe1. Is anyone out there trying to rehabilitate this line? It doesn't seem easy for Black.

Just FYI, I recently had a quick game against a correspondence GM, who was White.  He played 13.Qb3, but I was able to gain instant equality with 13...Nc5 14.Qa2 Be6!  Apparently the search for an advantage continues.

16...axb6 is indeed not easy to counter, but after some analysis i think i found interesting ideas for white to this position! The resulting positions are often far fom clear, in order to give final evaluations one should play this positions out,  but from a practically view easier to play for white.
As this time there are quite a lot variations, i made a pgn-file where you can find all my notes to this 12...0-0-0 variation.
Have fun with it and if you have suggestions for either side oder comments about the resulting positions, please tell! Wink


27. Nd5 is worth a serious thought in your line. It's quiet, but black has to avoid a lot of pitfalls. Normally I wouldn't care about lines up to the 27th move, but almost the entire continuation is forced anyway. Kudos on your entire idea though, I just don't think white's 27. Rd1 challenges black enough since the position you marked as += at the end is just extremely unclear (neither side is easy to play).

Sample line: 27. Nd5 Qxb2 28. Qf7+ Kc6 29. Qc7+ Kxd5 30. Rd1+ Ke6 31. Rxd8. White has two pawns for the B, and a continuing attack. I've tested a lot of variations after 27. Nd5 (ie: 27...Qc5, 27...Qd6, 27...Qd4), and so far it's been very promising.

Let me know what you think.

13.Nd5, a nice idea, but Pia probably showed the way to play for Black! In the game she was already slightly better after 23...Qb6!, so i looked for improvements for white. The only improvement i found was 19.bxc5 N
The idea is very nice: If e.g. 19...Kb8 then 20.c6! bxc6 21.Qc2 Rc8 22.Ne3 (threateting to take on d5) Bd6 23.Qd3 (threatening to take on d5) Qd7 24.a5 and i think, white gets quite good attacking chances against black king. One exampleline: 24...e4 25.Qb3+ now after 25...Qb7 26.Qa2 Ka8 27.a6 Qd7 there is 28.Nxd5! and with correct play from black white gets better endgame with weak black king. And after 25...Ka8 there is 26.Nxd5! Bxg3 (forced) 27.Nb6+! axb6 28.axb6! Bxh2+ (forced) 29.Kxh2 Kb7 30.Ra1 Ra8 31.Rfd1 Qe7 32.Kg2 (prophylaxis protecting f2) and the position is of course unclear, but i think white has the better chances because of the dangerous pawn on b6, blacks king can easily get under fire.
So everything looks very promising for white, but there is 19...Bxc5! and there is a forced line: 20.Ne3 Kb8 21.Nxd5 Bxf2+! 22.Rxf2 Rxd5 23.Qxd5 Qxc1 24.Kg2 Qc7 25.Rf7 Rd8! 26.Rxc7 Rxd5 27.Rxh7 and this rookendgame is objectively a draw for sure, but in praxis i woud say, white has slightly better chances.

Just another very recent attempt: 13. Nd5 cxd5 14. Ne3 Be4 15. Rc1 Nc5 16. b4 Bxg2 17. Nxg2 g5 18. Bxe5 fxe5 19. Qc2 Kb8 20. bxc5 Rc8 21. Qb3 Bxc5 22. Qxd5 Rhd8 23. Qb3 Qb6 24. Qf7 Rf8 25. Qg7 Qf6 26. Qxh7 Qxf2+ 27. Rxf2 Bxf2+ 0-1 Solomon, Kenny(2368) - Cramling, Pia(2528) /8th Gibtelecom Masters/ 2010-01-28.
This looks to me like a good game from both sides until White overlooked a straightforward mating attack at move 26.

Kaufman's survey in YB 93 is an interesting reading indeed, especially as he already covered two plans mention here in this thread as interesting or new:
  • 13. Nxe5 Nxe5 14. Qc1N a6 15. a5 Bc5 =
  • 13. Ne3 Be6 14. Ncd5N Qa5 15. Rc1 Nb6 16. Nxb6+ axb6 also assessed as = after some more moves.
I think Kaufman is working and carefully doublechecking with Rybka. But maybe there is some spot where engines underestimate the somewhat weaker position of the black king (which is a long-term factor). Any improvements here?

after 13.Ne3 Be6 my idea is the Novelty 14.Ncd5!
14...cxd5 is bad, you can analyze it yourself Wink
so critical is 14...Qa5 then 15.b4 leads to nothing, but 15.Rc1 Bc5 16.b4! Bxb4 17.Qb3 Bc5 18.Ne7+! Bxe7 19.Qxe6 seems strong, so 15.Rc1 Nb6 16.Nxb6 Qxb6 17.Qc2 g5 18.Bxe5 fxe5 19.Qe4! and you can analyze this position by yourself, i think white has a strong positional grip on blacks position, --> Nf5, b4-b5

so i'm interested, what NiC yb suggests for black after 13.Ne3!?

In the Ivanchuk-Nakamura game isn't 15.a6!? interesting? I have analysed 15...b5 with unclear play. Also i think that Black can play for a win after 15.Ra4 Kb8 and if now 16.a6 b5! Is this game analysed somewhere else?

@BPaulsen,
I'm not at my set right now but what about 16 Qd4 and not moving the knight followed by Be3/b4 for instance ??

I will try to post some analysis when I get back to my set and notebooks.

Regards,

Nelson. Smiley


16. Qd4 looks sufficient.

How about when black plays 14...Qa5, or 14...Qd6?

I myself chose 13.Ne3 so far and got some nice wins with it

@ Alias: can you post the analysis/suggestions for black from NiC yearbook after 13.Ne3 ?

the game gets very interesting after that move


13. Ne3 Be6 and it just seems like white's hard pressed to come up with a productive plan - what's your idea?

13. Nxe5 Nxe5 14. Qc1 has been promising so far in analysis I've done. I can't list much more as of right now because I'm still ironing out a lot of the continuations, but I can say that I haven't been impressed by alternatives, although I would be thrilled if something else ends up good, too.

White played 13.a5 Nc5! 14.Qe1, which led to a very quick draw in the Chuky-Naka encounter.

So, what does White do instead?

(I had rather feared 13.a5 before this game.)

@Alias,

16 Qc2 ? Roll Eyes


I was the one that mentioned it, but 16. Qc1 (more typical) is far from impressive either.

I'm waiting to see what white's idea after either move, then 16...Kb8. The N is getting driven back, and all white did was waste time with Nd5.

Feel free to supply some analysis instead of one move and a smiley face. Unless that's the best you've got.

Alias,

What did Ivanchuk play??

After O-O-O by black if I remember rightly Nxe5, Nxe5 followed by Nd5 is better for white.

Deos anyone have any views on this??

Nelson.


After 13. Nxe5 Nxe5 14. Nd5 Qf7 how is white supposed to proceed? If anything black is likely to come out with a better position and the initiative after something like 15. e4 Be6 16. Qc2 Kb8.

Nelson,

The game can be seen at http://www.chessgames.com/perl/chessgame?gid=1569920

The Hector novelty is 13.Qc1?! ("used to be considered best") 13...Nc5!N

The NiC yb article discusses 13.Nxe5 ("probably best"), 13.Ne3, 13. Ne4 and 13.Rc1 but not 13.a5.

Yes. That's the game. Larry Kaufman said that it could be the novelty of 2009. He has been trying it out himself as well.

0-0-0 in the Ne5, Qc7+f6 variation. Looks good. I've been enjoying g5 instead of f6, but I have to have a closer look at this.
