Posted by chuckventimiglia austinfilmfestival.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 austinfilmfestival.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 :) ——— The Man With Too Much Chess Talent — Dragoljub Velimirovic used to be one of the world's most feared attackers, always looking for the impossible. His imaginative play was compared to the colorful world chess champion Mikhail Tal's razzle-dazzle. His playing style was unique, daring and often falling off the edge. He made risky moves and so many of them that you wondered how much punishment his chess pieces could take. He loved to create confusion on the chessboard, always believing he could find a beautiful escape from a bad situation. He had enough talent to pull it off, perhaps "too much talent" as Bobby Fischer once put it when we discussed the play of the Serbian grandmaster and champion. At 68, Velimirovic doesn't seem to ...

RB If chess pieces could talk, they would be screaming at me something like: "Can't you take a hint, dummy? We're all pointing in one direction – at c3!" And I would say back to them: "Yes, thank you, I see that, but I have to tell you that I am always nervous of sacrificing a chess piece when I can't calculate a forced mate or win of material." But let's try to get the nerves under control and venture the less valuable piece first: 1...Bxc3. What's to stop White playing 2 bxc3, and if 2...Qxc3 3 Bb3, with threats against f7? That doesn't seem to help Black much, so what about the rook: ...
Posted by taufiq austinfilmfestival.org 4/15/2008 04:25:47 Play online chess	Thanks alot, Message: marinvukusic; things are all clear now :) Geert ——— Polgar Defeats a Slumping Topalov at Ajedrez Event — Marriage seems to have hurt Veselin Topalov’s chess career, for now. Topalov, 35, a former world chess champion who was ranked No. 1 in the world as recently as 14 months ago, has seen his ranking slide to No. 5. His manager, Silvio Danailov, said in a recent interview that Topalov married a few months ago and was “enjoying life a little bit,” adding, “He is not motivated to play chess tournaments right now.” Topalov may also be suffering from a sort of psychological hangover after losing a grueling world chess championship match in April and May to Viswanathan Anand. He has not really played well since. His latest setback occurred at the Ajedrez UNAM Quadrangular chess tournament in ...
Posted by sharpgate austinfilmfestival.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? ——— Magnus Carlsen suffers dramatic collapse at world blitz chess championship — The world blitz chess championship in Moscow has become a popular annual event. Vishy Anand, the world chess champion, stayed away this year but the world No1, Magnus Carlsen, who won in 2009, returned to defend his title in an elite 20-grandmaster field. Carlsen led after the first day's play but had a bad run ("My head went on strike") on the second and Armenia's world No3, Levon Aronian, went three points clear before easing up. Final leading scores were Aronian 24.5/38, Teimour Radjabov 24, Carlsen 23.5. The time limit shortened from four minutes per game plus two seconds per move for each side in 2009 to 3/2. It is tough to play a high-class opponent under such conditions. Quite apart from ...
Posted by chessnovice austinfilmfestival.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. ——— Chess: How to continue the attack? — Sometimes the way ahead is obvious, sometimes a little more obscure... RB The position arose from a Sicilian and, racking my memory, I vaguely recall that there are sometimes sacrifices on e6 and b5 in similar set-ups. So I looked, first, at 1 Ndxb5 (or 1 Ncxb5), but after 1...axb5 2 Nxb5 Qc6, Black has a knight for two pawns and White still has no attack. I then looked at 1 Nxe6, but again after 1...Bxe6 2 Bxe6 (what else?) fxe6 Black was, once more, ahead on material and under no threat. 1 Nf5 doesn't do anything either, apart from lose a piece for even less material, and 1 a4 is answered by 1...b4. The pawn on e4 is obviously a target, but ...
Posted by lighttotheright austinfilmfestival.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 austinfilmfestival.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 austinfilmfestival.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 austinfilmfestival.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 austinfilmfestival.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.
