Posted by chuckventimiglia goclub.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 goclub.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 :) ——— King Tut in Chess Puzzles — King Tutankhamun, or simply King Tut, is the most famous Egyptian pharaoh. He was called the boy-king since he was only nine-years-old when his 10-year reign began in 1,333 B.C. He died at the age of 19 and his tomb, undisturbed for 3,245 years, was well-preserved when it was discovered in 1922 by Howard Carter. King Tut's golden burial mask became the symbol of ancient Egypt. But how did he make it into chess? Protecting a king is vital in every chess game and pawns are best suited to do the job. When the pawns surround the king in chess problems and studies, we see some beautiful and astonishing creations. Entombing the king became a popular theme among chess composers ...

In a literal game of one-upmanship, an Iranian chess grandmaster played 614 people simultaneously on Tuesday and Wednesday at Shahid Beheshti University in Tehran in an attempt to break a world record set by an Israeli chess grandmaster last October. According to a report in Agence France-Presse, the Iranian, Ehsan Ghaem Maghami, 28, won 590 games, lost 8 and drew 16 in an exhibition that took 25 hours. The Israeli grandmaster, Alik Gershon, 30, played 523 games over 19 hours, beating 454, losing 11 and drawing 58. Mr. Gershon broke the previous record set by ...

And the World Open, which is held every year in the Philadelphia area around Independence Day, usually has more than 1,000 chess players between all its sections. But for sheer quality of competition, the annual Aeroflot Open, which starts on Tuesday, trumps them all. Sponsored by the Russian airline, the chess tournament is divided in three sections. The A group usually features many of the world’s top chess players, and this year is no different. Twenty-six of the world’s top 100 players are competing, and 73 of the 87 players in the top section are ...
Posted by sharpgate goclub.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? ——— Chess: The calculations of Vishy Anand — The Indian grandmaster is back on top of the world – and matches such as this demonstrate why. Over the next few weeks we are going to be looking at games by the world chess champion Vishy Anand. He recently regained the no 1 spot on the rating list, so this seems a fitting moment to feature his play. His depth and speed of calculation marked him out as a special talent in his youth, and he has lost none of that sharpness in his maturity. RB: What is the white knight doing on g5? This was the first thing to strike me when Dan sent me this position. Has it just captured a piece? Has it been trapped? Has there been a whole series of ...
Posted by chessnovice goclub.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. ——— A Victory to Remember for a Young American — Until a week ago, the short list of the greatest American tournament victories was limited to Hastings in 1895, Cambridge Springs in 1904, AVRO in 1938 and Palma de Mallorca in 1970. This year’s Tata Steel tournament in the Netherlands is now on that list. When it was over, Hikaru Nakamura had finished ahead of the top four chess players in the world, including the world chess champion, Viswanathan Anand. Garry Kasparov, the former world chess champion, said it was the most impressive victory by an American since 1895, when Harry Nelson Pillsbury, who was 22 and virtually unknown, finished first at the tournament in Hastings, England, in a field that included Emanuel Lasker, ...
Posted by lighttotheright goclub.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 goclub.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 goclub.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 goclub.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 goclub.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.
