Hello !

I again had a look at the 10.g3-variation and I must say now that in case of 13.Bg2!
(instead of 13.0-0-0 like in the Dominguez-Nakamura game) 13....Nc6 14.Qf2 with the idea 15.0-0 black does not have an easy life ...
White rules on the dark squares and may has some attacking chances in the future too.

Thank you very much dom, this seems to be the right reply to the g3-variation ! Smiley

Maybe white should prefer 10.Be2, if he intends to castle kingside. 10...Nxe5 is possible then, but I have some doubts that black can equalize completely this way.

One idea idea is to play a simple attack on the queenside:

10.g3 Bxd4 11.Bxd4 Nxd4 12.Qxd4 Nb8! 13.ooo Nc6 14.Qf2 Bd7 15.Kb1 Qa5 16.Bd3 Rfc8 17.a3!? (17.Qe1 Nb4 18.a3 Nxd3 19.Rxd3 Rc4 20.Qd2 Rac8 21.Ne2 Qxd2 22.Rxd2 Re4 23.Rc3 Anand-Shirov,Leon 2001 (Watson) and  now 23..Re3! 24.Rhd1 Rc4) b5!?

If White try to forbid the queenside attack as in following game:

[Event "Cuernavaca Young Masters"]
[Site "Cuernavaca"]
[Date "2006.02.03"]
[Round "5"]
[White "Dominguez,Lenier"]
[Black "Nakamura,Hikaru"]
[Result "1-0"]
[Eco "C11"]
1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.e5 Nfd7 5.f4 c5 6.Nf3 Nc6 7.Be3 cxd4 8.Nxd4 Bc5 9.Qd2 0-0 10.g3 Nxd4 11.Bxd4 Bxd4 12.Qxd4 Nb8 13.0-0-0 Nc6 14.Qc5 Bd7 15.Kb1 Rc8 16.Qd6 Na5 17.Bd3 Rc6 18.Qa3 a6 19.Ne2 b5 20.Nd4 Rc8 21.Rhe1 Re8 22.Nf3 Qb6 23.Qb4 Nb7 24.g4 Nc5 25.Qd2 b4 26.f5 Nxd3 27.f6 Qc5 28.cxd3 Qf8 29.Nd4 a5 30.Rc1 h6 31.g5 g6 32.h4 h5
33.Rxc8 Rxc8 34.Rc1 Ba4 35.Qe3 Qd8 36.b3 Bd7 37.Rxc8 Qxc8 38.Nc2 Bb5 39.Kc1 Qc3 40.Qd4 Qc7 41.Kd2 Bd7 42.Kc1 Kf8 43.Kb2 Ke8 44.a3 bxa3+ 45.Nxa3 Kd8 46.Nc2 Kc8 47.Qc3 Kb7 48.Qxc7+ Kxc7  49.Kc3 Kb6 50.b4 a4 51.Nd4 Ka6 52.Kb2 Kb6 53.Ka3 Be8 54.Ne2 Bb5 55.Nc3 d4 56.Ne2 Bxd3
57.Nxd4 Bc4 58.Kxa4 Bd5 59.Ne2 Bc6+ 60.Kb3 Bb5 61.Nf4 Be8 62.Kc4 Bb5+ 63.Kd4 Be8 64.Ne2 Bc6 65.Nc3 Bg2 66.b5  1-0

then Black can improve the line:

14.Qc5!? (keeping the queen on the kingside wing) Bd7 15.Kb1 Rc8 16.Qd6 a5! threatening a queen trap with Nb4-Rc6.

A) 17.Rd2 Na7! 18.h3 (or h4) b5 =/=+
B) 17.Bb5 Qb6 18.Bd3 (18.Qxd7 Rfd8 19.Nxd5 exd5 20.Bxc6 bxc6 and good chances for Black despide the minimal material deficit) Rfd8 19.Na4 Qb4 20.Qxb4 Nxb4 21.Nb6 Rc6 22.Nxd7 Nxd3 =
C) 17.Nb5 Nb4 18.Nd4 Nc6 19.Nb3 (19.Nxc6 Bxc6 20.Qa3 Qb6) b6 =

Welcome to the club! I don’t have any specific solution to your problem. But I can share with you some useful points.

First, imo, not withstanding stats, it is a general defense problem and not a opening problem. Both sides have short castled and one side has better space on the king side. Colours reversed, white can have similar problems in, lets say, 4.e3 Queens Indian. Black in that case can play Ne4, f5, g5-g4, Qg4, Rf6 etc. Similarly in your case f4-f5,g3-g4-g5-g6, Qd2-g5 etc. It can be quite menacing and one mistake can cost the game. I’ve been there.

In this case, shifting the knight to e4 if possible and playing c8 bishop to the long diagonal, strengthening the second rank defense with Rac8-c7, Qe7 etc and not moving the f,g,h pawns till the last moment are the standard defense techniques.

Seeking active counter play on the other side of the board may be difficult. But what is needed is passive defense on the king side while simultaneously preparing for future play on the queenside. Silver lining is that white has to make lot of concessions on the king side for such type of double-edged play.

Of course, none of what I wrote may be new to any of us here. The point I wanted to make is, a good book on defense is likely to help you better than ECO and DB stats. You might want to study the limited number of Black wins and draws, in this perspective.

C11: Who has an idea ?

I recently had problems with the following variation (with black):

1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.e5 Nfd7 5.f4 c5 6.Nf3 Nc6 7.Be3 cxd4 8.Nxd4 Bc5 9.Qd2 0-0 10.g3!? [10...a6 11.Bg2]. White intends to castle kingside and later attacks with f4-f5.
This variation has a very good score for white (71% in Corr 2006 and 68% in Mega 2006 database) , its indeed difficult for black to get enough counterplay.

Any ideas for black ?
