Posted by chuckventimiglia accuserveone.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 accuserveone.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 :) ——— McShane Retains Lead at London Classic; Anand Beats Carlsen — Luke McShane, who won his first two games, did not win in Round 3 of the London Chess Classic on Friday. But he managed to draw against Vladimir Kramnik of Russia, the former world chess champion, and thus remained in the lead. After three of the four games in each of the first two rounds ended decisively, Friday was relatively quiet, with three games ending in draws. The exception was a win by Viswanathan Anand of India, the world chess champion, over Magnus Carlsen of Norway. It was the second loss for Carlsen, who actually had an advantage early in the game before making two bad moves that allowed Anand to shatter his kingside pawns and then infiltrate with his queen and rook. Carlsen could ...
Posted by marinvukusic accuserveone.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 ——— Surprising Leader at London Chess Classic — The torrid pace continued at the London Chess Classic on Thursday as three of the four games again ended decisively. Luke McShane of England, who had pulled off a big upset by beating Magnus Carlsen of Norway in Round 1, won again in Round 2, beating Nigel Short, another Englishman. It was Short’s second loss. Carlsen bounced back by upending Michael Adams, one of the four English chess players. Hikaru Nakamura of the United States, who had managed to draw a long game against the world chess champion Viswanathan Anand of India in Round 1, had Black for the second game in a row. It was also his 23rd birthday. His opponent, Vladimir Kramnik of Russia, the former world chess champion, ended up ...
Posted by taufiq accuserveone.com 4/15/2008 04:25:47 Play online chess	Thanks alot, Message: marinvukusic; things are all clear now :) Geert ——— Exciting and Surprising Start to the London Chess Classic — If every round of the London Chess Classic is like the first round, then it is going to be a very exciting tournament. The chess tournament began Wednesday and three of the four games ended decisively. The most stunning result was the victory of the English grandmaster Luke McShane over Magnus Carlsen of Norway. Carlsen played some speculative moves and was punished brilliantly by McShane. The other two wins were also quite exciting. Michael Adams, one of the four English chess players, checkmated his countryman David Howell in 27 moves with a scintillating attack, while Vladimir Kramnik of Russia overwhelmed Nigel Short, the other English player, with a central pawn break that eventually led to ...
Posted by sharpgate accuserveone.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? ——— Women’s World Chess Championship Begins With Some Upsets — The first round of the Women’s World Chess Championship, which is being held in Hatay, Turkey, ended Monday, and a few of the higher-ranked chess players are already on their way home. The biggest upset was the victory of Betul Cemre Yildiz of Turkey over Pia Cramling of Sweden. Cramling was a semifinalist at the 2008 championship and is ranked No. 9 in the world among women. The manner in which she lost was also surprising as she simply used up all her time in the second game of her match before she could make her 40th move in a completely equal and uncomplicated position. Other upset victims included Lilit Mkrtchian of Armenia, who lost tie-breaker games Monday to ...
Posted by chessnovice accuserveone.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. ——— Chess: Battleground London — World chess champion Anand faces his nearest rival Carlsen at the London Chess Classic. The second edition of the London Chess Classic takes place at Kensington Olympia from tomorrow until 15 December. This year will be even stronger than last with the participation of the world chess champion, Viswanathan Anand from India. Anand was a frequent and popular visitor to England in his early career, but hasn't played a chess tournament here since 1995 and interest will be high, not least because he will be facing the player tipped to succeed him, the Norwegian chess prodigy Magnus Carlsen. Their meetings take on added significance with Carlsen's controversial withdrawal from ...
Posted by lighttotheright accuserveone.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 chessnovice accuserveone.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 accuserveone.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 accuserveone.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.
