9.Bc4 Bd7 10.Bb3 Rc8 11 0-0-0 Be5 12 Kb1 a6 can be mentioend as well. It does not  have a name but forum member Swiss Dragon suggested this move and after that Carlsen played it in several games and it was even played once by Radjabov. Maybee we can call it "Swiss variation" or "Carlsen variation". While black appears to be struggeling there at the moment but things can change and the draw game between Anand and Carlsen could even be reached via a Solits move order where whites most dangeorus moves in both Solits and a6 line are ruled out.


Can you tell me why black is struggling there? I thought Topalov-Carlsen was considered OK for black and after Khalifman's 17.f4 Nc4 18.Bxc4 Rxc4 19.f5 e5 20.fxe6 fxe6 21.Qd3 Rd4:!? might be playable for black (as stated somewhere here on the forum).


I agree the Khalifmans improvment is unconvicing but de La Villas improvment in Dismantling the Sicilian is more difficult to crack.

exchange for unsufficent compensation with whites attacking is still going on
and I cant fault him} *

Can u tell me how do you make your analyse? I don´t understand your moves. My brain and my engine give me better moves for black!

Ok I did a little research, and I got this conclusion:

After 13.a3 a5 white has 4 options:

1) 14.Nd5 transposing to a variation of the normal 13.Nd5. (It could be the most challenging maybe after all.)
2) 14.e5
3) 14.Rhe1

4) 14.Kb1 the debated one could follow 14...b4 15.axb4 axb4 16.Na2 and here:

4.1) 16...Be6 suggested before.
4.2) 16...Ra8 mentioned by me before after 17.Qxb4 turns complicated. Hopefully black will get compensation.
4.3) 16...Qc7
4.4) 16...Qa5

Well what can I say?. Still, there is room for investigation I guess.

I have my doubts about the way that has been played the ...Nxd4 system like in the game Karjakin-Shirov where it was 10.0-0-0 Rc8 11.Bb3 Nxd4 12.Bxd4 b5. Why is that?.

Because of 13.a3! a5 (Right eh? Or what?) 14.Kb1 a4 (14...b4 15.axb4! axb4 16.Na2 Ra8 17.Qxb4!) 15.Ba2 Rb8 16.Ne2 Be6 17.Bxe6 fxe6 18.h4 e5 19.Bc3 and white looks better.


I dont have access to any engine or books at the moment, but I have frankly not seen any games where white plays a3 or seen it mentioned in annotations at subscription part of this site. Hower in this system (invented by Topalov) black usually sacrifes a pawn for preusure agianst  queenside so intution suggests 14 .. b4 line. I will have a look at this on monday when I have access to books, databases and Rybka.

Maybe should I consider again 10.Bb3 as the best move to avoid the "Chinese Dragon"?. Maybe not.

"10 0-0-0 allows Chinese Dragon, one of blacks best scoring lines in practise."<-------- I hope you are right on this Bragesjo. The time and further analisys will tell.

In the "Parma Variation" 10.Bb3 Nxd4 11.Bxd4 b5:

- About De La Villa's 12.h4 a5 13.a4. I have my doubts. 13...bxa4 14.Nxa4 Rb8 15.0-0 Qc7 16.Rfd1 Rb4 17.Bc3 Rb5 18.Qe1 Rd8!?. (I don't have "Dismantling the Sicilian".)

- 12. a4 b4 13. Nd5 Nxd5 14. Bxg7 Kxg7 15. exd5 Qb6 16. h4  (recommended by Khalifman). I'll wait for further investigations on 12.a4.

About Parma variation, I have played it myself a couple of times and I never realy liked the lines where white plays for a positonal edge. If white goes after blacks king black is fine like Stellwagen-Tiviakov.

The two most critical lines are (Khalifman line was considered harmless by any existinng pre books/discs)

[Event "Blitz:3'+1""]
[Site "Hewlett-Packard Company"]
[Date "????.??.??"]
[Round "?"]
[White "New game"]
[Black "Rybka 3 32-bit"]
[Result "*"]
[PlyCount "25"]
[TimeControl "180+1"]

{128MB, Fritz10.ctg, 2.2 GHZ Dual Core 3 GB RAM} 1. e4 c5 2. Nf3 d6 3. d4 cxd4
4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 O-O 8. Qd2 Nc6 9. Bc4 Bd7 10. Bb3 Nxd4

{etc was recommended by Khalifman}) 12... a5 13. a4 {
was recommended in Dismatling the Sicilian} *

If you want to do the move order. Probably it is better 10.0-0-0 to try to crack down black. 10.Bb3 gives black 10...Nxd4 enough for equality. 10.h4 h5!. So 10.0-0-0 should be the one to look for advantage to white.
Initially I thought of 10.Bb3 as the best move until I found that the "Parma" variation is enough to control white's intentions. I have played it in correspondence, and I can assure that.
The point is what's better after 10.0-0-0????

About Sax variation, it can also be reached with Kb1 and Re8 inserted when the insertings favors white. However black is still fine as long as he knows what he is doing.

There is also a line that goes

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 O-O 8. Qd2 Nc6 9. Bc4 Bd7 10. Bb3 Rc8 11 0-0-0 Ne5 12 Bg5, acording to Andrew Martin it was invented by a player called Sax so we can call it Sax variation.

An other line is the dubios (but common at ameutur levels) 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 O-O 8. Qd2 Nc6 9. Bc4 Bd7 10. Bb3 Rc8 11 0-0-0 Ne5 12 Bh6 Bxh6 13 Qxh6 Rxc3 14 bxc3 sicne after Korchnois a5! black gets a strong attack. Maybee we can call it Korchnoi variation. If whites king had been at b1 and blacks f rook at e8 we would have reached Karjakin-Ivanchuk 2007 draw.

In practical play I have also meet 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 O-O 8. Qd2 Nc6 9. Bc4 Bd7 10 g4!?

and 9.Bc4 Bd7 10.O-O-O Rc8 11.Bb3 Ne5 12.g4? b5!

Maybee we can call it "Swiss variation" or "Carlsen variation". While black appears to be struggeling there at the moment but things can change and the draw game between Anand and Carlsen could even be reached via a Solits move order where whites most dangeorus moves in both Solits and a6 line are ruled out.


Can you tell me why black is struggling there? I thought Topalov-Carlsen was considered OK for black and after Khalifman's 17.f4 Nc4 18.Bxc4 Rxc4 19.f5 e5 20.fxe6 fxe6 21.Qd3 Rd4:!? might be playable for black (as stated somewhere here on the forum).


I agree the Khalifmans improvment is unconvicing but de La Villas improvment in Dismantling the Sicilian is more difficult to crack.

Lines added to the PGN file I am preparing.

I suposse that when you write 9.Bc4 Bd7 you mean 9...O-O. Is that correct?

Or it's a better move order play 8....O-O and then 9...Bd7?

TN wrote on 12/01/09 at 09:28:18:
I suggest including 7...Nc6 8.Qd2 Bd7 9.0-0-0 Rc8 and 9.Bc4 Bd7 10.0-0-0 Na5, which usually transposes to the Chinese Dragon after 11.Bb3 but also has an independent branch of its own after 11.Be2. In that variation, De La Villa prefers White but I'm not 100% sure about this if Black plays 11...Rb8 and ...b5.



Sorry, I wasn't clear.

I was referring to 7...Nc6 8.Qd2 Bd7 9.0-0-0 Rc8 and 7...Nc6 8.Qd2 0-0 9.Bc4 Bd7 although the move order doesn't make any real difference, since Black's alternatives to 9...Bd7 in the second line are generally considered to be dubious. The first 9...Rc8 variation is considered much better for White by De La Villa, but I'm not enough of an expert in this line to know how accurate this assessment is.
  

All our dreams come true if we have the courage to pursue them.
