Posted by chuckventimiglia chesspeak.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 chesspeak.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 :) ——— Endgames, part 1: Rook against Bishop — A superb lesson from Magnus Carlsen in endgame technique. It's been a while since we looked at the endgame, so this week we begin a short series on this often neglected area with a terrific demonstration of endgame technique from the ever-improving chess world No 1 Magnus Carlsen. Although White has the advantage of rook against bishop, Black has an extra pawn and a solid position on the chess board. How did Carlsen make progress? RB I'm pretty sure the answer lies in g4. The question is whether to nudge the pawn forward immediately or whether some preparation is needed first, perhaps exchanging on d5 or advancing the king to e3. The only way is concrete calculation, so let's see what ...
Posted by marinvukusic chesspeak.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 ——— Dortmund Begins — The Sparkassen Chess-Meeting (an odd name, to be sure) began Thursday in Dortmund. Though the chess tournament is not at the level of Linares or Corus, it still attracts top players, notably Vladimir Kramnik, the former world chess champion from Russia. Kramnik has been associated with Dortmund, as the chess event is often referred to, for many years because he has won the tournament nine times, far more than any other. He first won it in 1995 and is the defending champion this year. The tournament is a double-round robin this year, meaning each competitor plays all the others twice, once with each color. In addition to Kramnik, the No. 4 chess player in the world, the field includes ...
Posted by taufiq chesspeak.com 4/15/2008 04:25:47 Play online chess	Thanks alot, Message: marinvukusic; things are all clear now :) Geert ——— Zhao and Zatonskih Lead Chess Championships — Anna Zatonskih, the defending chess champion, took the lead of the U.S. Women’s Championship on Wednesday, while Parker Zhao, the ninth seed, solidified his grip on the U.S. Junior Championship. The two chess tournaments are being held concurrently at the Chess Club and Scholastic Center of Saint Louis. Zatonskih had shared the lead for the last few rounds with Irina Krush, the top seed. But in Round 5 on Wednesday, Zatonskih beat Iryna Zenyuk, while Krush only drew against Camilla Baginskaite. Zatonskih now leads with 4.5 points, while Krush and Tatev Abrahamyan, who beat Abby Marshall on Wednesday, have 4 each. In the junior championship, Zhao, who ...
Posted by sharpgate chesspeak.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? ——— A Chess Odyssey — One single square can make a big difference in a chess game. It helped me to launch one of my longest combinations against Anatoly Karpov in Caracas 40 years ago. It was a memorable chess tournament for both of us. Karpov arrived in Venezuela as the reigning world junior champion. He played well enough in Caracas to become the world's youngest chess grandmaster at that time, at age 19, and his brilliant career began to take shape. In 1971 in Moscow, he clinched the first major tournament victory, sharing first place with the three-time Soviet champion Leonid Stein at the prestigious Alekhine Memorial tournament. In 1975 he was crowned the world chess champion. This year ...
Posted by chessnovice chesspeak.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. ——— Fast Pace Continues at Two U.S. Chess Championships — The top two seeds in the U.S. Women’s Chess Championship could make no headway against each other and drew their Round 3 game on Monday. But their two nearest competitors lost, so Irina Krush and Anna Zatonskih now lead the chess tournament by half a point over Tatev Abrahamyan, Alisa Melekhina (who lost to Abrahamyan on Monday) and Iryna Zenyuk, who lost on Monday to Beatriz Marinello. In the U.S. Junior Chess Championship, which is being held concurrently at the Chess Club and Scholastic Center of Saint Louis, Warren Harper, the seventh seed, is the surprising leader after three rounds with a perfect score. His play so far has been stellar and on Monday he demolished his ...
Posted by lighttotheright chesspeak.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 chesspeak.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 chesspeak.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 chesspeak.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 chesspeak.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.
