Posted by chuckventimiglia play-online-chess.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 play-online-chess.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 :) ——— Big Surprises in Europe — Europe has been a center of chess activity over the last month with a series of major open tournaments. The first was the Gibtelecom Chess Festival in Gibraltar, which ran from Jan. 26 through Feb. 4. Among the world-class chess players who competed were Etienne Bacrot of France, Sergei Movsesian of Slovakia, Francisco Vallejo Pons of Spain, Michael Adams of England, and Gata Kamsky of the United States. The chess tournament ended in a nine-way tie for first, with Adams winning a four-person playoff to take the title. The Moscow Open, which overlapped with Gibtelecom and ended on Feb. 7, was divided into four sections — A, B, C and D — with ...

Alexander Grischuk of Russia, the defending champion, is in second place after beating Vugar Gashimov of Azerbaijan in Round 8 on Sunday. Levon Aronian of Armenia is in third, having managed, like Topalov, not to have lost a game in the chess tournament. Unlike Topalov, who has won three games, Aronian has not won a game either. So far, 25 percent of the games have been decisive, but that does not mean that the other 75 percent have been dull. Quite the contrary. The games have mostly been hard fought and exciting, even ...
Posted by taufiq play-online-chess.com 4/15/2008 04:25:47 Play online chess	Thanks alot, Message: marinvukusic; things are all clear now :) Geert ——— Weekend of Fun and Friends Between Battles on the Chess Board — The highlight of the year for many chess players is Washington’s Birthday weekend, when four amateur team championships are held across the country. There are no cash prizes, but the chess tournaments are popular because of the camaraderie. Players walk back and forth chatting before, after and even during the games. Some renew friendships with competitors they see only once a year. The World Amateur Team East tournament in Parsippany, N.J., the biggest and oldest of the chess events, celebrated its 40th birthday this year. There were 1,150 players and 271 teams, down from 283 teams last year, said Steve Doyle, the tournament’s director, who ...
Posted by sharpgate play-online-chess.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? ——— At Halfway Point, Topalov Leads at Linares — The annual Ciudad de Linares chess tournament in Spain began earlier this week, and after five rounds — or halfway through — Veselin Topalov of Bulgaria, the top seed and No. 2 chess player in the world, is leading with 3.5 points, a point ahead of the field. Linares has been among the world’s elite chess tournaments since the early 1990s, when Garry Kasparov and Anatoly Karpov were regular competitors. This year’s tournament has only six players, though they are all among the world’s best. The format is a double round robin in which each chess competitor faces all the others twice, playing once with White and once with Black. Aside from Topalov ...
Posted by chessnovice play-online-chess.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. ——— The f-pawn, part 1: cheap, crude and obvious? — Is an f-pawn advance the chess game's equivalent of route-one football? RB For some time I've been nagging Dan to do a series of columns on the f-pawn advance. He's been resistant, partly, I suspect, because pushing the f-pawn is a bit like route-one football, the long ball punted down the park in hopes of a quick goal. The advance can sometimes be crude, obvious and speculative, but, like the infamous route-one game, it can also produce results, and, as we will see over the next few weeks, some very classy chess players have used it. We start with one of the classiest of all time, Botvinnik, in a chess game played in the decade before he became world chess champion. Having ...
Posted by lighttotheright play-online-chess.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 play-online-chess.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 play-online-chess.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 play-online-chess.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 play-online-chess.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.
