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 :)
Posted by marinvukusic mailcafe.net 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 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?
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.
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.
Chess news: Flu virus keeps competitors in check at Tal Memorial — Ten of the world elite are competing at Moscow's Tal Memorial, which ends today and is one of the strongest tournaments in chess history. But the winner in the chess event's first half was a flu virus which affected several grandmasters and encouraged a minimalist, cautious approach. Ukraine's Vasily Ivanchuk wore a face mask, and a high 80 per cent of the first five round games were drawn. The sickest chess player was Magnus Carlsen, 19, who had trained beforehand with Garry Kasparov and was expected to unleash some opening bombs in his campaign to become world No 1. But Norway's golden teen was close to defeat against Vlad Kramnik in the opening round and then ... French chess star wins world junior — Maxime Vachier-Lagrave of France edged Sergei Zhigalko of Belarus to win the World Junior Chess Championship in Puerto Madryn, Argentina. Each scored an undefeated 10 1/2 -2 1/2 in the 82-player tournament, the most prestigious age-limited chess event. Only players born in 1989 or later were eligible. Vachier-Lagrave, 19, earned the chess grandmaster title in 2005 and won the French championship in 2007. He entered the tournament as the top seed with a rating of 2718 (23rd in the world), but his triumph was hardly guaranteed in an upset-filled melee that included 16 other grandmasters, including six rated above 2600. Zhigalko, 20, was seeded third ... Kramnik triumphant in Moscow — Former world chess champion Vladimir Kramnik won the flu-stricken Tal Memorial on Saturday. Playing more deliberately and sharply, the Russian grandmaster reinvented himself. He did not mind dwelling in complications and kept his cool in difficult situations. He withstood the last-round charge of Ukraine's Vassily Ivanchuk, last year's winner of the same chess event. Magnus Carlsen sneaked in a tie for second place by winning the last two games. The Norwegian grandmaster gained enough rating points to move into the world's top spot. The world chess champion Vishy Anand of India had a chance to tie for first with Kramnik, but lost in the last round with the white pieces to ...
