Posted by chuckventimiglia razlending.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 razlending.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 :) ——— Vishy Anand saves his strength before world match with Veselin Topalov — Vishy Anand, who defends his world title against Veselin Topalov at Sofia in April, kept his powder dry in his warm-up chess event at Corus Wijk where the Indian, 40, played at full force in only a few games. In contrast Topalov, 34, has played hard in almost every game this week at the Linares elite chess tournament in Andalusia, where he won first prize with 6.5/10, half a point ahead of Russia's Alex Grischuk. The Bulgarian squeezed points from tiny advantages and by round six had regained the world No1 spot on the live chess ratings from Magnus Carlsen. These daily updated rankings have a huge following and their prestige is now not far short of ...

It pits Judit Polgar of Hungary, the strongest woman chess payer in history, who is now ranked No. 46 in the world, but once was in the top 10, against Gregory Kaidanov, a Ukrainian-born American grandmaster, who is ranked No. 261. The match is four games and has an interesting twist: Each game begins with a different variation of the Sicilian Defense. The first game was on Monday and was won by Kaidanov, who had White, and featured the Sveshnikov. The second, which was won by Polgar, was on Tuesday and was a Dragon. The third chess game, which is being played on Wednesday, and can ...
Posted by taufiq razlending.com 4/15/2008 04:25:47 Play online chess	Thanks alot, Message: marinvukusic; things are all clear now :) Geert ——— The f-pawn, part 2: is f5 the answer here? — Does White have a better option than moving the f-pawn? Continuing our look at the chess equivalent of route one football – the f-pawn advance... RB Well, let's see what happens when we push – 1 f5. The answer comes back faster than Manchester United on the break, not much. Black is under no compulsion to take the pawn and can instead centralise with 1…Nd4 or even 1…Qd4, or start getting the queen's rook into play with 1…Rac8, and 1…Nb4, hitting the d-pawn, would be irritating. All right, let's try to be logical. What's wrong here is that even if we could swap off pawns on the f-file, the f1-rook would remain blocked by the bishop. Let's ...
Posted by sharpgate razlending.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? ——— Big Surprises in Europe — Europe has been a center of chess activity over the last month with a series of major open tournaments. The first was the Gibtelecom Chess Festival in Gibraltar, which ran from Jan. 26 through Feb. 4. Among the world-class chess players who competed were Etienne Bacrot of France, Sergei Movsesian of Slovakia, Francisco Vallejo Pons of Spain, Michael Adams of England, and Gata Kamsky of the United States. The chess tournament ended in a nine-way tie for first, with Adams winning a four-person playoff to take the title. The Moscow Open, which overlapped with Gibtelecom and ended on Feb. 7, was divided into four sections — A, B, C and D — with ...
Posted by chessnovice razlending.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. ——— Topalov Closes In on Linares Title — After eight rounds, Veselin Topalov of Bulgaria, the top seed, holds a one point lead in the annual Ciudad de Linares chess tournament in Spain. Alexander Grischuk of Russia, the defending champion, is in second place after beating Vugar Gashimov of Azerbaijan in Round 8 on Sunday. Levon Aronian of Armenia is in third, having managed, like Topalov, not to have lost a game in the chess tournament. Unlike Topalov, who has won three games, Aronian has not won a game either. So far, 25 percent of the games have been decisive, but that does not mean that the other 75 percent have been dull. Quite the contrary. The games have mostly been hard fought and exciting, even ...
Posted by lighttotheright razlending.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 razlending.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 razlending.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 razlending.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 razlending.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.
