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.
Apr-16-08  Wild Bill: Congratulations to Greg Kaidanov for winning the Gausdal Classic today.

Way to go, guy.

Apr-22-08  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!

  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.

  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.>

  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.

  diagonal: GM Kaidanov, inductee of the U.S. Chess Hall Of Fame - Portrait:

<Born in Berdychiv, Ukraine, USSR, Gregory Kaidanov learned chess from his father at the age of six. In the 1980s, he won many international tournaments while playing for the Soviet Union, and he earned the title of Grandmaster in 1988. Three years later, he and his family immigrated to the United States, settling in Lexington, Kentucky.

In 1992, he had an impressive string of victories, tying for first in the Chicago Open, before winning the top prizes in the World Open and the United States Open Championship.

Kaidanov also scored many great successes while playing for American teams. He played in the Olympiads six times between 1996 and 2006, winning a team bronze in 1996, a team silver in 1998, an individual silver in 2004, and a team bronze in 2006. Kaidanov also competed in the World Team Championships three times between 1993 and 2005, winning a team gold and an individual silver in 1993, and a team silver and individual gold in 1997.

His major tournament victories include the mentioned 1992 World Open, and 1992 U.S. Open, as well as the first Aeroflot Open in Moscow in 2002, and the last Gausdal Classic (international invitational tournament) in 2008.

Kaidanov, who is one of the most active Grandmaster teachers in the U.S., also coached the 2008 U.S. Womenís Olympiad Team to third place.>

For further tournament wins, see also in the cg. box above, ie. Kaidanov took the closed New York Manhattan together with veteran Efim Geller in 1990:, and co-won the Hastings Masters in the same year.

  OhioChessFan: I remember another game in the simul I cited 8 years ago. The game started 1. e4 e5 2. Qh5 g6. (I admit losing a skittles game to that once and my opponent being shocked when I resigned after Qxe5). The hapless patzer-an adult man, not a kid-played on until mate, and seemed completely oblivious to what a breach of etiquette that was. Move after move, Kaidanov came to that table and moved instantly. When it got to the last 3-4 players, just about everyone was wondering why the guy didn't resign, wondered how he couldn't notice Kaidanov had to stop at all the other boards and not just slap a piece down as he walked by. As time went on, I realized the guy had probably never played a game where either side resigned. Just that skittles stuff where you play it out to mate.

Anyway, it was truly maddening when it was over that one of the patzer's friends came up and said, "Good work, you held on for a long time." I probably wasn't the only one who wanted to tell him what everyone else thought.

  Sally Simpson: Hi Ohio,

Some taking part in a simul view it as them against him (or her) a team event rather than a skittles solo game v the master.

Anyone who resigns early is then chastised and I've heard of cases where one lad has pepped talked the 'team' prior to the master appearing telling everyone not to resign because this gives a better chance to the rest of the tem. Keep him playing.

Also, it is not uncommon for casual players to think you must play on till you are mated and resigning is unsportsmanlike akin to sulking.

Premium Chessgames Member
  perfidious: <Geoff>, a most interesting viewpoint--in my simul days, I never witnessed such behaviour.
Premium Chessgames Member
  Sally Simpson: He perfidious,

I gave the same 'team' a pep talk prior to the Edinburgh C.C. new season curtain raiser, last's years club champion takes on the club champion in a sumul. That year is was Keith Ruxton.

I wanted him to score P.20 L.20. Sadly he won the lot.

I get that, but I wouldn't go along with it-unless it was a clock simul. At the Kaidanov simul, the other breach of etiquette I saw was a Master level player, on the University team, who thought it was cute to blitz out a 5 move combination. Kaidanov went along with it, and clearly saw farther than the Master, who looked a bit chagrinned at Kaidanov's last move. As it turned out, the last man standing was a bit below 2000. At the time of the 5 move blitz, I thought he was going to have a stroke when he saw that other player making things easy on the GM.

  perfidious: Dang, Kaidanov's hourly rate was half that when I worked with him in 2000-01.

  Dionysius1: Where did you see his rates? I'm always curious how GMs earn their money.
