Posted by sharpgate play-chess-online.com 4/14/2008 16:25:41 play online chess	Subject: ratings Message: Does anyone know how to approximate a 1700 GN rating to USCF rating? Ron
Posted by chuckventimiglia play-chess-online.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-chess-online.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 :)
Posted by marinvukusic play-chess-online.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

Posted by sharpgate play-chess-online.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?
Posted by chessnovice play-chess-online.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.
Posted by lighttotheright play-chess-online.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 play-chess-online.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-chess-online.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-chess-online.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.
Chess news: The Great Chess Doping Scandal -- Chess Grandmaster Vassily Ivanchuk refused to submit a urine sample for a drug test at the Chess Olympiad in Dresden and is now considered guilty of doping. The world of chess is outraged that he could face a two-year ban. Professional chess player Vassily Ivanchuk, born in Berezhany, Ukraine in 1969, has been a grandmaster for the past 20 years and is currently ranked third in the world. The man with black hair and bedroom eyes is known as "Big Chucky" by his fellow chess players. Why? Because, after losing a game, he goes into the forest at night and howls at the moon to drive out the demons. Because he walks around in shorts in freezing temperatures. Because he likes to ... Magnus Carlsen quits Grand Prix -- The World Chess Federation (FIDE) plans to begin the third tournament of its Grand Prix series today in Elista, Russia. The first two Grand Prix tournaments were unqualified successes, featuring exciting chess battles between many of the world's top 20 grandmasters. The forecast for the rest of the series is less rosy. When organizers of Grand Prix chess events in Qatar and Switzerland backed out, FIDE President Kirsan Ilyumzhinov moved the Qatar tournament to his hometown of Elista and announced that Armenia would host a chess tournament. But FIDE also changed the rules, making the Grand Prix leader merely one of eight contenders in a tournament that ... Chess, by Lubomir Kavalek -- The defending chess champion, the Dallas Destiny, won the 2008 United States Chess League, a 14-team Internet competition that ended this month. Dallas's final match against the Boston Blitz was tied 2-2, but IM Davorin Kuljasevic won the title for Dallas, defeating former U.S. chess champion Larry Christiansen in the last game of the blitz tiebreak. An Attacking Gem. Before the match went into the tiebreak, Christiansen smashed IM Marko Zivanic with a powerful attack, most likely to be the best game of the competition. It matters to the Boston grandmaster how he wins. He created many beautiful combinations and spectacular sacrifices during his successful ...
