Posted by chuckventimiglia intochess.com 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 intochess.com 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 intochess.com 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 intochess.com 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 intochess.com 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 intochess.com 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 intochess.com 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 intochess.com 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 intochess.com 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 intochess.com 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: Favorites Begin Quickly at U.S. Chess Championship -- Hikaru Nakamura, Gata Kamsky and Alexander Onischuk, the top three seeds, all won their first games Friday at the United States Chess Championship in St. Louis. Five other chess players also won as the tournament got off to a fast and exciting start. The chess championship is being held at the Chess Club and Scholastic Center of Saint Louis and has a prize fund of $173,000. It has an unusual format this year. The first seven rounds will be a regular Swiss system in which players with the same number of points are paired. After seven rounds, the top four scorers will be separated from the rest of the tournament and play a round-robin amongst themselves, with the winner becoming chess ... With One Blunder, Challenger Lets Chess Champion Keep Title -- Some consider chess an art form, others a math problem to be solved, but at its heart it is a competition. Anyone who watched the more than 2,000 children competing at the National Elementary School Chess Championships in Atlanta last weekend could see that. At the top levels, the competition is fierce, and the psychological pressure can be overwhelming. That is why even the best chess players make mistakes. The world chess championship match between Viswanathan Anand of India and Veselin Topalov of Bulgaria, which ended last week in Sofia, Bulgaria, illustrated that pressure. Each made blunders, culminating in one that led to Topalov’s loss in Game 12. It was ... Vishy Anand defeats Veselin Topalov to retain World Chess Championship title -- It was scarcely a vintage or error-free world chess championship, yet Vishy Anand's 6.5-5.5 victory over Veselin Topalov proved a combative scrap with subtle match strategies. The 40-year-old title holder from Chennai beat the Bulgarian 3-2 with seven draws in their €2m (£1.7m) series in Sofia. Anand won the crown in a 2007 tournament, then comfortably retained it against Vlad Kramnik in 2008, and so joins a rare elite of multiple chess champions. This time the margin was narrow, the games tense and long as Topalov, five years the younger, spurned draws and kept up sustained pressure. The Bulgarian had his chances, but a poor sense of danger proved his fatal weakness. All his ...
