Kibitzer's Corner
< Earlier Kibitzing  · PAGE 1 OF 8 ·  Later Kibitzing>
Mar-11-03  Cyphelium: A wonderful game. Yusupov sacs almost everything and when Ivanchuk starts giving it back to save himself it's already too late.
Mar-11-03  kostich in time: This, indeed, is an Immortal Game..I believe its the only game to receive straight tens from the Informant Jury.
Jul-08-03  JGD: One of the greatest games of all time.
Jul-08-03  drukenknight: Strong evidence that allowing a pawn on the 6th rank is a serious positional problem.
Jul-14-03  kutuzov: Why does chessgames.com think this game's opening is the english? Looks more like the king's indian defense.
Jan-13-04  Benjamin Lau: 30. Qg8+! (apparently the only move preventing forced mate), sacrificing the queen, is necessary in view of the horrible threat 30. (non-interfering move) Qh1+!! 31. Bxh1 Nh2+ 32. Ke1 Rg1#. Other defenses seem to fail. If 30. Bxf4??, then 30...Qxf4+ 31. Kg1 Qh2+ 32. Kf1 Qh1+!! and the basically same mate happens. 30. Ne6 (either knight) also fail. Any corrections to my analysis are appreciated however, as this is a complicated game. Anyway, this is a really nice attacking game from Yusupov.
Mar-09-04  Benjamin Lau: By the way, what's the most recent word on the soundness of this game? Critics are divided on this one.
Mar-24-04  Jim Bartle: Seirawan calls the opening the King's Indian Fianchetto in his serious analysis, but he think he called it the Modern the first time.

The big mistakes appears to be 13, f4, allowing the e3 pawn to control d2 and f2 forever, and moving the wrong knight to e7 on move 25. Apparently Ivanchuk realized his mistake when he had the piece in the air, but then it was too late. Even if he'd played Nce7, it was still an incredibly complicated game that it appears black could have won.

7 of the 9 Informant judges rated this game #1, while Smekjal and Speelman rated it third (and Speelman put another Yusupov win over Ivanchuk at #1).

Mar-25-04  Dillinger: There is a web page I found which annotates this game here, http://www.lifemasteraj.com/great_c..., incorporating some of the earlier analysis as well such as Seirawan's. I can't vouch for it as I haven't looked through it yet, and the final position he gives seems to be wrong, but check it out if you're interested.
Mar-25-04  Jim Bartle: Now that is some seeeerious analysis! Still, surprising he doesn't mention that Ivanchuk obviously just unintentionally picked up the wrong knight on move 25.
Apr-10-04  Benjamin Lau: Jim, is Yusupov vs Ivanchuk, 1991 the game Speelman decided to rate 1st?
Apr-10-04  WMD: The Goldsby page points out that Black's move 37 was Kh8 not Kg8.
Apr-10-04  Jim Bartle: Interesting. Seirawan's book has Kh8, but the Informant "Golden Games" issue of 1995 has Kg7. At a glance, it doesn't seem to matter a whole lot.

Yes, Benjamin, that's the game Speelman rated #1, the game that gave Yusupov the chance even to play THIS game. Several others also rated it #2, after this game.

By the way, the Chess Informant had a poll on the greatest games it had ever published (1966-1995) and this game came in first in the readers poll. I think the GM poll ranked the 16th game of the 1985 Karpov-Kasparov match as #1.

I don't know how many people remember what a huge upset the Yusupov win was. At this point Ivanchuk looked invincible, having won tournament after tournament, including Linares, having beaten Yudasin 4.5-0.5 in the previous round of the candidates. And Yusupov had recently recovered from being shot during a robbery in his home.

Apr-10-04  Jim Bartle: Sorry. In the previous message, second line, I meant Kg8.
Apr-10-04  WMD: Next time I see Ivanchuk I'll ask him.
Apr-10-04  Benjamin Lau: WMD, you talk to Ivanchuk on a regular basis??
Jun-11-04  dac1990: This game, according to Seirawan, was G/45. It's amazing that these guys can calculate that fast.
Jul-12-04  coxscorner: The losing move appears to be 25. Nde7+? whether intentional or not.

The correct defense of 25. Nce7+ looks to fail at many glances (not just first) to the amazing tactic 25...Kh8 26. Nxf5, Qh2+. 27. Kf1, Be5!! preventing Bxf4 for one tempo, while opening up the g-file for the rook on a8. This appears exceedingly dangeroous to white, and could explain Ivanchuk rejecting the line if that were the case. If now 28. Bxe5+, Rxe5 29. dxe5, Rg8! (threatening 30...Qh1+! 31. Bxh1, Nh2+ 32. Ke1, Rg1#) 30. Ndxe3 (the only move) 30...fxe3 31. Nxe3, Qf4+! 32. Bf3, Nxe3+ 33. Ke1, Rg1+ 34. Kf2, Ng4+! 35. Kxg1, Qh2+ 36. Kf1, Qf2#

But white can survive with the better position with the following: It should be noted however, that it literally took a team of Grandmasters days to find this line of defense through anlaysis, something that was impossible to do over the board. Black's attack was very practical.

25. Nce7+, Kh8 26. Nxf5, Qh2+. 27. Kf1, Be5!! And now white has to play 28. dxe5!, Rg8 (same threat as above line 29...Qh1+!) 29. Ndxe3, fxe3 30. e6! (White must guard h2. If instead 30. Nxe3, Qf4+ 31. Ke1, Nxe3 and blacks attack is still decisive) and blacks attack collapses.

The actual game continuation with Yuspov's 27...Re6! and 28...Rg6!! place this game amongst the immortals.

Jul-27-04  dac1990: 25. Nde7+?? was indeed Ivanchuk's mistake. Seirawan gives that Ivanchuk grabbed the d-Knight, paused, then (with a grim look) finished the move. D'oh!
Jul-30-04  kevin86: Indeed,a very odd game. It seems that black sac-ed several pieces to put his opponent into a chokehold;then white tries to save himself with his own give-aways,but to no avail.
Jul-30-04  Knight13: Very interesting king hunting game. The black pawn on e3 helps the queen on g3 mate easly. Interesting.
Jul-30-04  psalcido: Seirawan says that the moral of this game is only allow your opponent to push his pawn to e3 if you can take it. I think that this is a good overall analysis, as that pawn cost him the entire game.

This game was not played over normal time controls and it was during a government coup occuring in Russia. The reason that the time controls were changed was because the opponents here were very evenly matched, and were tied after something like 30 games. I can't remember the exact time controls ... 60 moves in 30 or 45 minutes? It was some number like that. The emotional state of the players and the extreme time controls are shown with some of the play -

but they are still WAY BETTER than me.

Jul-30-04  notyetagm: In that Informant poll, Anand rated this game #1.
Jul-30-04  dac1990: Game in 45 minutes was the time control.
Jul-30-04  Jim Bartle: Time control was 60 moves in 45 minutes. This was the first of two playoff games after an eight-game match at classic controls was tied.
