Posted by chuckventimiglia blitzbrain.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 blitzbrain.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 :) ——— 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 ...

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 taufiq blitzbrain.com 4/15/2008 04:25:47 Play online chess	Thanks alot, Message: marinvukusic; things are all clear now :) Geert ——— 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 sharpgate blitzbrain.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? ——— Anatoly Karpov out for a fight — Anatoly Karpov and some supporting chess federations have filed a lawsuit against FIDE in the Court of Arbitration for Sport in Lausanne. Karpov's lawyers, White & Case, are a global firm based in Manhattan. They seek nothing less than the disqualification of the incumbent FIDE President Kirsan Ilyumzhinov who is standing for a fifth term. The rules demand that at least one member of a Presidential ticket be female and Ilyumzhinov's choice is American WIM Beatriz Marinello. Supporting documents indicate Ms Marinello was not nominated by the US Chess Federation but by her native Chile and Brazil. Karpov contends she is not even a member of either chess federation. Karpov's lawyers also ...
Posted by chessnovice blitzbrain.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. ——— Players Sense Opportunity in Opponents’ Losing Streaks — Momentum from a few wins can buoy a chess player and cause opponents in future rounds to wilt. It can happen the other way around, too. A couple of losses can lead opponents to become like sharks sensing blood. When chess players are on losing streaks, opponents are reluctant to settle for draws and will instead press on, hoping for victory. Players on losing streaks also often begin second-guessing their decision-making and analytical skills, leading to more mistakes and more losses. That is why it is often said that the most important thing to do after a loss is to get a draw in the next game in order to stop the bleeding. The consequences of failing to do so, even among elite chess ...
Posted by lighttotheright blitzbrain.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 blitzbrain.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 blitzbrain.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 blitzbrain.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 blitzbrain.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.
