Posted by chuckventimiglia mailcafe.net 4/14/2008 19:01:23 Play online chess	You can't!! Message: You may approximate it to a USCF CC rating but not OTB.
Posted by taufiq mailcafe.net 4/15/2008 00:25:42 Play online chess	... Message: Can someone explain what GN, USCF, OTB stands for ? CC is correspondence chess, right ? Thanks in advance :) ——— After Decades in Top Ranks, a Shot at the Title, Finally — Chess players usually reach their peak in their 20s, so how is it that the grandmaster Boris Gelfand is getting his first crack at becoming world chess champion when he is 43? Gelfand, whose Candidates Matches victory in May earned him the right to play Viswanathan Anand for the title next year, said he was encouraged by the example of Viktor Korchnoi. When he was in his late 40s, Korchnoi, now 80, played for the chess championship twice. “Korchnoi is kind of inspiration for me and for all of us,” Gelfand said in a recent telephone interview, quoting Korchnoi’s advice that “if you want to improve, you have to learn new things all the time.” Gelfand said he changed his opening repertory before ...

The world chess governing body Fide will now decide between Chennai and an earlier bid from Moscow. Magnus Carlsen, world No1 at 20, and Sergey Karjakin, No4 at 21, are exceptional for their age, yet they now face a challenge from two still younger chess grandmasters who are advancing fast up the rankings. Italy's Fabiano Caruana, 18, took first prize at New Delhi last month and is ranked in the top 20 GMs, while Anish Giri, 17, won the Dutch chess championship by a two-point margin. Giri is reaching his rating targets at a younger age than ...
Posted by taufiq mailcafe.net 4/15/2008 04:25:47 Play online chess	Thanks alot, Message: marinvukusic; things are all clear now :) Geert ——— Bobby Fischer: How the king of chess lost his crown — By Garry Kasparov. Bobby Fischer was the chess world’s flawed genius. His mercurial brilliance was undisputed, but his fragile mental health led to poisonous and very public outbursts - especially after 9/11 - that prompted global revulsion. Garry Kasparov, himself world chess champion for 20 years, remembers with fondness and frustration the man he most wishes he had played: It would be impossible for me to write dispassionately about Bobby Fischer even if I were to try. I was born the year he achieved a perfect score at the US Chess Championship in 1963, 11 wins with no losses or draws. He was only 20 at that point but it had been obvious for years that he was destined to become ...
Posted by sharpgate mailcafe.net 4/15/2008 06:33:48 Play online chess	Message: this is the issue. 40 years ago when I played on my college chess team I had a USCF rating of about 1500. 40 years later my GK rating is about 1700. Am I getting better or worst? ——— When not seeing is believing — This week Toronto is hosting the 2011 Canadian Open Chess Championship, and although I was not able to participate in the tournament, I had the unique good fortune to be there for the weekend to conduct a blindfold simultaneous exhibition. This is not the first time I have played multiple games of chess while blindfolded, but this one upped the ante. My usual blindfold limit is five boards simultaneously, and I've played with this set up a number of times. But this time I was pitted against six people, a feat I have only accomplished once - and that was more than 25 years ago. Adding to the challenge was the strength of the chess players. Normally, I recommend my opposition to be ...
Posted by chessnovice mailcafe.net 4/15/2008 06:48:41 Play online chess	... Message: If I were in your shoes, I would take the optimist's route and believe that you are better than you were 40 years ago. That said, I think the GK rating generally inflates the "true" value of your rating ("true" because who's to say that USCF is all that accurate, either?). There's also the possibility that your skill level remained about level. Did you read any chess books over the past few years? Have you gone over many of your games to find where you make mistakes? Do you find yourself noticing more or less inspired moves when you're playing? Either way, if you've played for the past 40 years, I'd find it hard to believe you're getting worse. ——— From the archive, 12 July 1972: Fischer's late opening gambit in Reykjavik — Originally published in the Guardian on 12 July 1972. Boris Spassky and Bobby Fischer finally made it to the world championship chessboard tonight and there was an almost palpable sense of relief throughout the auditorium at the sports stadium here, that chess had at last taken over from the ballyhoo. Yet Fischer was characteristically late. Promptly at 5pm Spassky walked on to the stage accompanied by the West German referee Herr Lothar Schmid, who had raced back to Iceland from his son's car crash in West Germany. Spassky immediately played his opening pawn to Queen four, and the match was underway. Spassky sat for a while and then walked around the board. Five minutes later ...
Posted by lighttotheright mailcafe.net 4/15/2008 21:12:13 Play online chess	Message: OTB is different. On GK, you have more time to make the move. Your quality of game should improve because of less time pressure. A 1500 game played on GK is going to look more accurate on average than one played OTB at the presumed same class level. Some people cannot necessarily translate their skills at GK to OTB, nor OTB skills to GK performance. These are different skills sets that are difficult to transfer. Yet, just playing more accurate more often should eventually improve OTB play. It just takes time.
Posted by fmgaijin mailcafe.net 4/16/2008 03:30:50 Play online chess	Chessnovice: Message: If you doubt the accuracy of GK ratings vs. other CORRESPONDENCE ratings, check out the performance of Cairo's team of GK players (Peace: The Power That Preserves) in the ICCF team championships (see links on his player page) or Rodog's ICCF performances (see links on his player page).
Posted by chessnovice mailcafe.net 4/16/2008 04:39:39 Play online chess	... Message: I don't doubt the relative strength of their ratings. I'm certain that Cairo's team is very talented. I just know from my personal vantage point... I don't really believe I play at an 1800 level.
Posted by fmgaijin mailcafe.net 4/16/2008 04:53:13 Play online chess	Still Thinking "Absolute" Message: Even though you acknowledge in the first clause that chess ratings are relative to the population of the rating group, your last clause shows that you are still thinking of "1800 level" as some absolute. All it actually reflects is your position in a particular population of players, because that is all that Arpad Elo's system is designed to show. Thus, one cannot even compare Fischer's 2800 rating with Kasparov's or Topolov's because they lived in different times and even though they played in the same rating system, the population changed as players aged, died, and were replaced. If you hold a GK 1800 rating across some significant number of games and did not get it via timeouts, etc., then you are playing at an 1800 level IN THAT POPULATION.

Posted by bonsai mailcafe.net 4/24/2008 23:53:09 Play online chess	Message: And of course you can add or subtract any number you please from ratings. One would approximately expect a 1800 on gameknot is to score about the same against a 2200 on gameknot as a 2000 FIDE versus a 2400 FIDE (i.e. the rating difference means the same thing), at least if their past performance is indicative of their chess strength. However even if the two ratings measured the same kind of skill (which they probably don't exactly), then it would still not be clear which points on the scales correspond to each other. Of course if the rating were comparable, then one would be able to look at players that have both ratings and possibly be able to figure out a reasonable conversion. However as said before we probably have to expect that CC and OTB ratings simply measure two related, but not identical kinds of past performance.
