Feb-14-05  iron maiden: They haven't put up the round 1 pairings yet, despite the fact that the tournament starts in just a few hours.
Feb-14-05  WillC21: what time(EST) does the tourney start and how can we watch it live?
Feb-15-05  hintza: <WillC21> You can watch 60 games live here:

The first round begins at 15:00 Moscow time, which I believe is 07:00 EST.

<iron maiden> The pairings have been put up now. You can find them at

Jan-29-06  BIDMONFA: Gregory Kaidanov

KAIDANOV, Gregory S.

Oct-03-06  Karpova: <Kramnik goes into an endgame where he's worse, and there is nothing you can do about it.>

Today's quote is really hilarious! Thanks <>!

Oct-03-06  jackmandoo: so does this quote mean that you're going to lose even though you have the advantage? Just because he is so good?
Oct-03-06  hitman84: <jackmandoo>It means you cannot lock everything in the world or maybe Kaidanov aided by fritz made the comment while playing against Kramnik.
Oct-03-06  ARTIN: <jackmandoo> It means that although Kramnik's position is "worse", the opponent cannot get more than a draw.

Of course, objectively speaking there are no "worse" endgames. There are won, drawn and lost endgames. The quote is praising Kramnik's ability to be able to distinguish which seemingly "worse" endgames are lost and which are drawn.

Oct-11-06  BIDMONFA: Gregory Kaidanov


Sep-13-07  dx9293: Kaidanov's greatest accomplishment no doubt was winning the very first Aeroflot Open held in 2002, ahead of 81 other GMs.

  Wild Bill: Congratulations to Greg Kaidanov for winning the Gausdal Classic today.

Way to go, guy.

Premium Chessgames Member
  Knight13: Except that this guy dropped like 100 rating points. (99, if you wanna cut somebody's head off for being too general)
Sep-29-08  zoren: He absolutely nuked in SPICE cup... probably out of practice being a full time coach.
Oct-11-08  just a kid: Happy Birthday Kaidanov!
Feb-23-10  Albertan: I have posted analysis of the first game of the Sicilian Theme Match between GM Kaidanov and GM Judit Polgar to the first page of my blog at using the program Chess viewer deluxe. The game is number 41 in the games index in the Chessviewer deluxe program. I hope you drop by and play through this analysis.The analysis was done with the assistance of Deep Rybka 3 and Deep Shredder 12 on my quad core computer.

  OhioChessFan: I met him at a simul once, though I didn't get to play him. He went 20-0 and finished in about 2 hours. I was surprised what a lighthearted personality he had. Before the match, he mentioned he was the highest rated American, but carefully explained in his Russian accent that he wasn't born here. One of his opponents was a father/son combo. About 10 moves in, the father made a blunder. Kaidanov blitzed out about 6 plies to show what was wrong, the father slapped his forehead in exasperation, but Kaidanov then reset the pieces and offered the son to make a different move.
Oct-14-10  Albertan: Here is a video about GM Kaidanov:

Oct-14-10  BobCrisp: Something that <Kaidanov> alludes to in the vid.

<Gregory’s first day in America was on a visit in the summer of 1990, in the pre-Guiliani New York, when the city was notorious for a high crime rate. He and his wife were robbed twice in one day! In addition to his savings, he lost 10 years worth of chess analysis. He was devastated.>

Feb-01-14  thegoodanarchist: Greg, you probably do not remember me because our last lesson together was about 15 years ago, but I think you are a superb chess teacher!

  TheFocus: <During my lessons I constantly emphasize the importance of open files and activity of the pieces. Unfortunately, the majority of club players worry more about such things as doubled pawns and weak squares, rather than worrying about the fact that their pieces are passive> - Gregory Kaidanov.
