Kibitzer's Corner
Sep-30-10  Marmot PFL: Sad that Ivanchuk had to lose, but good game by Mamedyarov.
Sep-30-10  goodevans: A complete disaster for Ivanchuk after such a brilliant start to this tournament.

Oddly, Stockfish disliked more of Mamdyarov's moves than Ivanchuk's, labelling <28 f4>, <34 Qf6+>, <37 Qf3> and <40 Nc4> as "Weak" whilst labelling all of Ivanchuk's first 40 moves as either "Optimal" or at worst "Suboptimal".

Even with all these so-called weak moves Mamedyarov still managed to open Ivanchuk right up by move 40, requiring only 8 more moves for victory.

Sep-30-10  parisattack: Patent Mamedyarov. Great clash between the two most formidable power players of our day.
Oct-01-10  Whitehat1963: Looks bad for black, but what's the finish?
Oct-01-10  I play the Fred: <Looks bad for black, but what's the finish?> Only three possible responses to 48 g5+:

1) 48...♔h5 49 ♕h7+ ♔xg5 50 ♘f3+
2) 48...♔xg5 49 ♘f3+
3) 48...♕xg5 49 ♘f7+

Oct-01-10  Whitehat1963: It's always the knight moves that elude me! Damn it!
Oct-01-10  LIFE Master AJ: I guess you must be a genius ... to defeat one.
Oct-01-10  computer chess guy: Move 31:

I think .. ♘d5 was necessary.

Oct-02-10  Albertan: I have analyzed this game with the assistance of Chessbase 10, Chessbase Megadatabase 2010 and the World's strongest chess program, Deep Rybka 4x64 on my quad-core computer (for 2 hours in analysis mode) and posted this analysis to the first page of my blog at: http://albertan1956.blogspot.com/ using the program Chessviewer Deluxe. I hope you drop by and play through this analysis. This is game 17 in the Chessviewer Deluxe game index. Deep Rybka 4x64 showed exactly where Ivanchuk made his errors in this game. Instructions as to how to use Chessviewer Deluxe are posted on the first page of my blog.
Oct-02-10  Jafar219: This is the best game in Chess Olympiad (2010)
Oct-02-10  Hesam7: <computer chess guy> you are right. After the forced sequence: 31. ... Nd5 32. Qxd5 Be6 33. Qxd8+ Rxd8

the rook on a3 is trapped! White has to lose an exchange: 34. Rb3 (34. Raa1 Bxa1 35. Rxa1 Rd3! gives Black an even better version of the endgame) 34. ... Bxb3 35. Bxb3 Rd7 (Black has to defend f7) 36. Nc4 (attacking a5) 36. ... Bc3:

Black has 3 pawns for the knight, White is definitely better but Black has good drawing chances.

Oct-02-10  ounos: Sigh. Fateful, I guess. Their last serious decisive game was the disaster (for Ivanchuk) at Ivanchuk vs Mamedyarov, 2007, three years earlier.

  ajk68: <I Play the Fred>: 48... Kxg5 49. Qe7+!!
49... Kh5 (trying to save the queen) 50. Qh7+ Kg5 51. Qxg6#

or

49... Kh6 50. Qxh4+ Kg7 51. Rf7+ Kg8 52. Qh7#

or

48... Qxg5 49. Nf7+ Kh5 50. Nxg5 Kxg5 51. Qe7+ Kh6 52. Qh4+ Kg7 53. Rf7+ Kg8 54. Qh7#

or ...

the variations go on, but every one I have seen ends in mate pretty readily.

Oct-04-10  I play the Fred: Very cool lines, <ajk68>!

I just saw something that worked "well enough" and stopped; I have got to learn not to settle for less.

Oct-05-10  donehung: The way Mamedyarov plays in this game reminds me of Alekhine, probably the reason hes one of my favorite top gms these days. Bravo
Oct-06-10  kurtrichards: <6.5/7> ...and here comes the stopper.
May-12-11  notyetagm: https://webcast.chessclub.com/icc/i...
Feb-07-12  parisattack: A Shak-and-Awe game I must have missed. Plus another Mamedyarov pawn-on-d6.

Allowing Shak a fluid center just can't be the best idea...

Oct-14-14  onam: 39 Ae6 The key move in the attack is also limiting the chances of Black's knight for the retreat and help in the defence.
