I'm a bit surprised that there is no mention of the Kramnik-Svidler game from this year's Tal Memorial, which ended in a resounding success for Kramnik.

Here's the annotations to the game by IM Robert Ris on ChessVibes:

Kramnik, V. vs Svidler, P. 1-0 Tal Memorial Rnd:4 Moscow RUS 2009.11.083.

1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Be3 c5 8. Rc1 Qa5 9. Qd2 O-O 10. Nf3 Bg4 11. d5 Na6 12. h4!?

Like yesterday in Morozevich-Kramnik, the h-pawn quickly leaves its initial square. 12. Ng5 was seen before in the blitz game Grischuk-Morozevich, Almaty 2008.
12... f5

played after 30 minute think.
13. exf5 Bxf5 14. h5 Rad8 15. hxg6 Bxg6 16. Bh6 Bxh6 17. Rxh6
17. Qxh6 Qxa2
17... Rf6
17... Nc7 18. Ne5
18. Ne5 Qa4

Threatening 19...Qe4.
19. Qe3! Qf4

There is nothing better than playing this inferior ending. 19... Rxd5? 20. Bc4 19... Qe4 is now met by 20. Rxg6+ 19... Nb4 20. Nxg6 20. cxb4 Qxb4+ 21. Qc3 Qf4 20... hxg6 21. Qh3! +-
20. Qxf4 Rxf4 21. Nxg6 hxg6 22. Rxg6+ Kf7 23. Rg5 Re4+
23... Nc7 24. c4 e6
24. Be2 Kf6 25. Rh5 Kg6 26. g4 Rf8 27. Rd1

With the idea to transfer the rook to h3.
27... Rf6 28. Rh8 Kg7 29. Rd8 Rb6 30. f3 Re3 31. Rd3
31. Kd2! Re5 32. Bc4
31... Re5 32. Kf2 Rh6 33. Bf1 Rh2+ 34. Kg3 Rxa2 35. d6 exd6 36. R3xd6 Re7 37. R6d7 1-0

I can't see a route to equality after 12.h4 for Black, so it seems that 10...Bg4 is insufficient for equality and Black should prefer 10...cd4 as recommended on the Forum. I recall that 10...Rd8 11.d5 e6 12.c4 Qd2 13.Nd2 Na6 is the other major line, although I think White should keep an edge there.

10...O-O 11.Rb5 cxd4 12.Rxa5 dxe3 13.Qxe3 Nxa5
14.h4!?-Le6! 15.Ng5!? (Dautov-Svidler,Istanbul 2000 played 15.h5)

) 7.Nf3 c5 8.Be3 Qa5 9.Qd2 Nc6 10.Rc1 cd4 11.cd4 Qd2 12.Kd2 0-0 13.d5 Rd8 14.Ke1 Na5 15.Bg5
I think it is much easier to play 15.--Kf8!? and White has only one good move 16.Ld3 to get an equal game!
In a game between Gasthofer and Yandemirov White played 16.Ld2?! and lost after 16.--b6 17.Rc7-Rd7 18.Rxd7-Bxd7 19.Ba6-e6 20.Ke2-exd5 21.exd5 -Re8! 0-1 (45)

The main problem for black is to struggle for the win in this variation.
It would be interesting to know if somebody has an idea on this.


If I recall correctly in the 10.Rb1 line mentioned by TN Black has a queen sacrifice he/she can play: 10...O-O 11.Rb5 cxd4 12.Rxa5 dxe3 13.Qxe3 Nxa5.

What is the logic behind 11.Rc1 ? Hasn't White any more useful move?

What about the Russian Variation? Or are there any other lines that are positional and good? Say maybe some g3 lines (I like my bishop there Smiley )


Why don't you ask about this in a thread not devoted to the Be3 Exchange?

Hmm, what other line do you recommend then? I expect my opponents to know the theory Sad


I recommend combining the 7.Nf3 c5 8.Be3 move order with the 7.Be3 (followed by postponing Nf3) move order. I wouldn't fear your opponents knowledge of theory for the following reasons:

a) The variation hasn't been fashionable since 2001, so there is a good chance that your opponents will not have seen it.
b) There is a very high chance that your opponent will deviate earlier, due to either not knowing the theory, forgetting the theory, or fearing an improvement and deviating.
c) Even in the 'equalising' line, the onus is on Black, and Kramnik's game against Van Wely in 2001 shows that there are still several pitfalls and traps that Black can fall into.
d) Most of your opponents will not own the relevant issue of ChessBase Magazine, or read this Forum. Wink

And there is always the interesting 7.Bg5!? if you are in an experimental mood.

The antidote to this line is covered in CBM 123, by GM Krasenkow. Here are the two most important lines:

a) 7.Nf3 c5 8.Be3 Qa5 9.Qd2 Nc6 10.Rc1 cd4 11.cd4 Qd2 12.Kd2 0-0 13.d5 Rd8 14.Ke1 Na5 15.Bg5 Bd7 16.Bd3 Rdc8 17.Ke2 e6 and White has a slight initiative but Black equalises without too much difficulty. See the annotated games in Mega Database.

b) 10.Rb1 (in my view this is slightly more accurate than 10.Rc1 but still does not offer any advantage against best play) 10...a6 11.Rc1 cd4 12.cd4 Qd2 13.Kd2 f5 and Black has full equality according to Krasenkow.

My stated '25 moves of theory' is an exaggeration - 20 moves of theory is more accurate.

I'll tell you when someone plays it against me. Wink

I'll give you a hint: the equalising line is available in an issue of CBM.

This is an excellent practical weapon, that probably deserves to be labelled as a 'Dangerous Weapon', but there is one catch: If Black knows 25 moves of theory, he completely equalises.

However, not one of my opponents as Black (in about 5 games) have ever come close to equalising, so there is a very probable chance that your opponents will not know the single equalising line for Black either.

I was looking through some crushing Kramnik wins in a particular line of the Grunfeld:

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Nf3 c5 8.Be3

I am pretty impressed by the wins, and wonders if this line is still theoretically interesting. Is there a lot of theory in this line? I do not mind some theory, but I hope they are less tactical in nature.
