Thank you dear Raivis /"Lazy Frank" for taking up our little 2018-analysis of this very famous Gambit within an already famous Gambit-line.
It was first publicly shown to a wider audience by Topalov vs. Kramnik at the Corus tournament 10 years back (though first shown by Romanian Miron Nacu at the ICCF chess-olympiad 2007) and made it the main-topic on the front-page of newspapers! - most likely the last chess-related topic having that "honour".



:smile:

The Gambit² is considered drawn or even slightly disadvantageous for White (score<50%), so let's see whether a '18-look can offer new insights in it.

Enjoy and have fun! Anton

Seems you put me in position where i have no choice! :twisted:
Thanks, Anton, have a look closer ...
Can you write down notation?

> Can you write down notation?


Not doing so was already my first trick! :twisted:
But fun aside, i have now to carefully look at all the alternatives before moving on (yes, i love sidelines! :wink:)...

Oh, and in the meantime, you liked "the original idea of Qc2!" in general or in a certain line (13.f4!?) which White didn't play?

Take your time! That is all what we (people) actually have!
Parent - - By Antares (****) [de] Date 2018-05-13 15:13


Must admit i didn't overanalyze, yet i think that 16. Bg4 is already asking for a lot of trouble:
In a quick (engine-)main-line 16. Bg4 h5! (Karjakin's bittersweet pill, everything else should
give White a decent play) 17. Bxh5 Bh6 18. Qg4 Raf8 19. h4 c5 20. hxg5 Bg7 21. g6 N7f6!
22. Bh4 Qxd6 * White is simply dead-lost!, with the only reasonable "improvements"
being 19. a4 or 19. b4 (where the first one can still transpose, and the second gives
absolutely no attacking-potential at all).

In each case i may take now a pretty long time, position is VERY critical. :wink:
Parent - - By Lazy Frank (****) [gb] Date 2018-05-13 15:19
Exactly. Bg4 i will met with h5 ... (a bit overcross Topa's immortality) :twisted:
Parent - - By Antares (****) [de] Date 2018-05-13 15:42
I could have even lived with 19...Rhg8!?, but 19...c5! with 21...N7f6 is just a massive improvement which leaves 19. h4 very questionable.
Parent - - By Lazy Frank (****) [gb] Date 2018-05-13 15:47
If we lead to 21... N7f6, i would say: Dead win.
Parent - - By Antares (****) [de] Date 2018-05-13 19:28
Also thought so, but the strange thing is that nearly every corr-game played 19. h4 but none got replied 19...c5, so either there is some refutation i/we don't know or those guys all had more luck than sanity. :grin:

Btw., a little IP-address analysis indicated that your connection belongs to a Mr. Alexei Shirov... please explain! :lol:
Parent - - By Lazy Frank (****) [gb] Date 2018-05-13 20:04
:surprised: As i know Alexey live in (also represent) Spain.

Friend of mine long time ago played few games against Shirov onto Riga's central park 'Vērmaņdārzs' benches.

Must admit my hope was really to find something in 16. Bg4, but while i indeed did :lol:, it was for Black... :yell:
At least i/we would have busted a dozen corr-players between 2006 and now, which interestingly
-thinking without that 16. a4-idea- rehabilitates Nacu's original 13. f4 as well.

> it's only move that avoid the draw


Nice! Wished Uly would have a little of that spirit (he choses always the moves who avoids the wins)! :twisted:

Think with 19. b3!? White also an interesting draw/option in hand... what was your draw-option here instead of Rhg8, can you give a line?
Parent - - By Lazy Frank (****) [gb] Date 2018-05-15 08:02
I didn't overlook b3 option, like you would have played axb5.
So, room for post-mortem analyse.
Parent - By Antares (****) [de] Date 2018-05-15 08:42 Edited 2018-05-15 08:45
Till here it was Grischuk-Liren (WCC 2018/Berlin), which continued 20...Bc6, where Black after 21. f4 should play 21...h5 instead of Liren's 21...gxf4?, which loses on the spot to 22. Bh4+ +/-. Even against 21...h5 i think White has some nice attacking-ideas, but there may be better 21th-moves currently not known to me.

Way more challenging is 20...Ba6 (21. f4 b4!), which AlphaGrischuk himself showed in the press-conference after that game. I think i found an interesting resource there, but eval was still very modest and more or less some (deep-hidding) wonder would be needed for White to win. 20...b4 may obviously have the same spirit in case White still has to play 21. f4.

In each case it is just VERY impressive how Grischuk prepared for this OTB-game... easily outcalculating every corr-game played till now as 16. Bg4 is simply not good at all!
Parent - - By Antares (****) [de] Date 2018-05-15 12:43
There are no promising alternatives, so in the spirit of AlphaGrischuk...

Quickly checked yesterday evening, but there seems to be absolutely nothing left to [re]set fire on board - White has no threats but a billion way to draw... Rgh8 damps out perfectly every Qc2/Qg4-idea, gives [drawing-]threats on g2 as well - most likely the best move at Black's disposal.
