Posted by chuckventimiglia austinfilmfestival.org 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 austinfilmfestival.org 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 austinfilmfestival.org 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 austinfilmfestival.org 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 austinfilmfestival.org 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 austinfilmfestival.org 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 austinfilmfestival.org 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 austinfilmfestival.org 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 austinfilmfestival.org 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 austinfilmfestival.org 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: Magnus Carlsen closes in on Garry Kasparov's record chess rating -- Magnus Carlsen is closing in fast on Garry Kasparov's all-time record chess rating. The 19-year-old Norwegian scored an unbeaten 7.5/10 at Medias, Romania to take his score on the daily calculations up to 2826, just 25 points shy of the great Russian's peak mark. And Carlsen did it while still not in optimum form. He began with two draws, then took risks including a 1 e4 e5 2 f4 King's Gambit and a couple of dubious positions, but his inventiveness and will to win coupled with the growing Carlsen-fear of those on the other side of the chess board ensured another impressive outcome. Technically his most interesting game, certainly from the practical viewpoint of competition ... Impressive Field at World Open -- The World Open, the annual chess tournament in Philadelphia that always takes place around July 4th, often lives up to its name by attracting a world-class contingent of chess players. This year is no different as the field includes Francisco Vallejo Pons of Spain, Surya Shekhar Ganguly of India, Loek Van Wely of the Netherlands, Luke McShane of England, Evgeny Najer of Russia, Viktor Laznicka of the Czech Republic and Ilya Smirin of Israel. It also includes many of the best Americans, among them Gata Kamsky, the United States chess champion, and Alexander Onischuk. The players come because the tournament offers one of the biggest prize funds in the world. This year’s is ... Magnus Carlsen Survives on His Wits -- One of the reasons that Garry Kasparov was the world’s dominant chess player from the late 1980s through the ’90s was that he was better prepared than his competitors. He spent an enormous amount of time researching chess openings for new ideas to spring on his opponents, or he paid others to do it for him. Magnus Carlsen, currently the world’s top-ranked chess player, is beginning to be as dominant as Kasparov was, but it is not because of his preparation. He has described himself as a bit lazy, and so rather than play the most popular chess openings, which everyone has studied, he often chooses systems, particularly as White, that do not yield any advantage. Carlsen wants to ...
