Posted by chuckventimiglia beck-web.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 beck-web.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 :) ——— Playing for the World Title, Minus Any Fireworks — Before a world chess championship match, players spend months looking at their opponent’s games and studying opening systems, often with the aid of chess computers and databases. They also hire trainers, who are called seconds, to help. It is a time- and labor-intensive process. That is one of the reasons that fans look forward to the chess matches. They want to see what the players will do and what new ideas they have discovered, particularly in the openings. The current world chess championship match between Viswanathan Anand of India, the titleholder, and Veselin Topalov of Bulgaria has been as closely contested as predicted. But there have been no eye-opening innovations. Game ...
Posted by marinvukusic beck-web.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 ——— With Another Draw, Chess Championship Match Remains Tied — Game 10 of the world chess championship match between Viswanathan Anand of India, the titleholder, and Veselin Topalov of Bulgaria, ended in a relatively uneventful draw on Friday. With only two games remaining in the best-of-12 series, the players are tied with 5 points apiece. If the match should remain tied after the last two games — which is a real possibility at the moment — it would go to a tie-breaker of four rapid games (each player starts with 25 minutes and has 10 seconds added to his time after each move). Such a tie-breaker was used in the 2006 world chess championship match between Topalov and Vladimir Kramnik of Russia. After each player won a game, and one ended ...
Posted by taufiq beck-web.com 4/15/2008 04:25:47 Play online chess	Thanks alot, Message: marinvukusic; things are all clear now :) Geert ——— Title Match Remains Tied After Champion Misses Win — With the world chess championship match having entered a critical stage, Viswanathan Anand of India, the titleholder, switched openings in Game 9, hoping to recapture momentum and the lead that he relinquished with a loss in Game 8. He almost did. But, with victory in sight, Anand faltered and missed a couple of winning continuations, which allowed Veselin Topalov of Bulgaria, the challenger, to salvage the game and keep the best-of-12 match tied. In each of the previous games he had White, Anand had steered the opening into the Catalan system, which is solid, but not too dynamic. In Game 9, he played 3 Nc3 instead of 3 Nf3 for the first time. That gave Topalov ...
Posted by sharpgate beck-web.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? ——— The Best Woman in Chess Still Stands Alone at the Top — Judit Polgar is the only woman to ever be ranked in the world’s top 10, or even in the top 100. At age 34, her ranking has slipped to 51 (from No. 8 in 2005) as the responsibilities of being a wife and mother — she has two children, ages 3 and 5 — have left her little time to train and compete. Since 1991, when Polgar became the youngest chess grandmaster in history, more than a dozen women have also earned the title. Two of them, Humpy Koneru of India and Hou Yifan of China, became grandmasters when they were even younger than Polgar. But no other woman has been able to break into the chess elite. Koneru is 23, and Yifan is only 16, so it seems likely that ...
Posted by chessnovice beck-web.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. ——— Topalov Wins to Tie Championship Match — Veselin Topalov of Bulgaria, the challenger for the world chess championship, broke through stubborn defense by Viswanathan Anand of India, the chess champion, to win Game 8 of their title match. The score is now tied at 4 points apiece. Since winning Game 1, Topalov had been stymied and outplayed. Though he had not been in any real trouble since losing Game 4, he also had not been able to find a chink in Anand’s armor, that is until Tuesday. Topalov was White and the opening was a Slav Defense, just as in Games 3 and 5. After 12 moves, the players reached the same position as they had in the earlier games, which Anand drew easily. He was the first to deviate, choosing ...
Posted by lighttotheright beck-web.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 beck-web.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 beck-web.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 beck-web.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 beck-web.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.
