Posted by chuckventimiglia goclub.org 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 goclub.org 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 :)
Posted by marinvukusic goclub.org 4/15/2008 00:47:29 play online chess	Translation Message: GN = GameKnot (should be GK) USCF = US Chess Federation OTB = Over The Board CC = Correspondence Chess

Posted by sharpgate goclub.org 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?
Posted by chessnovice goclub.org 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.
Posted by lighttotheright goclub.org 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 goclub.org 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 goclub.org 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 goclub.org 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 goclub.org 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.
Chess news: Chess legend Bobby Fischer dead at 64 -- Chess legend Bobby Fischer, whose tortured genius earned him both worldwide acclaim and disdain, has died at the age of 64 at his home in Iceland. "I can confirm that he died yesterday in his home due to an illness," close friend Gardar Sverrisson told AFP. Fischer was reportedly hospitalised for a period last year. Einar Einarsson, the chairman of a Fischer support group in Iceland, said the cause of death was kidney failure. "He was not a man who wanted to seek medical attention. He didn't believe in Western medicine," Einarsson told AFP. US-born Fischer, who made world headlines by defeating Soviet world champion Boris Spassky in a celebrated Cold War chess showdown in Reykjavik in 1972, took Icelandic citizenship in 2005 to avoid being deported to ... Chess Master Bobby Fischer Dies at 64 -- Bobby Fischer, the reclusive chess genius who became a Cold War hero by dethroning the Soviet world chess champion in 1972 and later renounced his American citizenship, has died. He was 64. Fisher died in a Reykjavik hospital on Thursday of kidney failure after a long illness, his spokesman, Gardar Sverrisson, said Friday. Born in Chicago and raised in Brooklyn, N.Y., Fischer faced criminal charges in the United States for playing a 1992 rematch against Boris Spassky in Yugoslavia in defiance of international sanctions. In 2005, he moved to Iceland, a chess-mad nation and site of his greatest triumph. As a champion, he used his eccentricities to unsettle opponents, but Fischer's reputation as a genius of chess was soon eclipsed, in the eyes of many, by his ... Fischer Versus the World: A Chess Giant’s Endgame -- There may be only three human activities in which miraculous accomplishment is possible before adulthood: mathematics, music and chess. These are abstract, almost invented realms, closed systems bounded by rules of custom or principle. Here, the child learns, is how elements combine and transform; here are the laws that govern their interactions; and here are the possibilities that emerge as you play with signs, symbols, sounds or pieces. Nothing else need be known or understood — at least at first. A child’s gifts in such realms can seem otherworldly, the achievements effortlessly magical. But as Bobby Fischer’s death on Thursday might remind us, even abstract gifts can exact a terrible price. In 1956 Mr. Fischer, at 13, displayed chess powers that were not only prodigious but ...
