Posted by chuckventimiglia kttstudios.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 kttstudios.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 :) ——— On Chess: Is struggling Anand looking ahead? — Recent months haven’t been kind to reigning world chess champion Viswanathan Anand, who posted mediocre results in three consecutive chess tournaments. His last effort — the London Chess Classic, in which he scored six draws, one loss and just one win — was, in his words and by his standards, “a disaster” not befitting the status of world chess champion. No doubt he was distracted, in part, by preparations for an upcoming May title defense against Boris Gelfand in Moscow’s renowned Tretyakov art gallery — a venue that Anand hopes will inspire “ beautiful and artistic chess.” Based on their past performances in hundreds of games, Anand is an almost a 3-to-2 favorite to win the 12-game match. He also has ...
Posted by marinvukusic kttstudios.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 ——— Chess: The Year in Review — Chess again crossed paths with politics in 2011, with the most remarkable moment occurring in Tripoli, Libya, during the NATO bombing campaign against Col. Muammar el-Qaddafi. Kirsan Ilyumzhinov, the World Chess Federation president, flew to Libya in June and played Qaddafi. Ilyumzhinov had known the Libyan leader since at least 2004, and there was speculation that he was on a mission to try to end the war. The game ended in a draw, but the war continued. (Tripoli fell to the rebels two months later, and Qaddafi was killed in October.) Politics also shadowed an achievement by Ehsan Ghaem Maghami, an Iranian chess grandmaster who set a record in February by playing 614 people at ...
Posted by taufiq kttstudios.com 4/15/2008 04:25:47 Play online chess	Thanks alot, Message: marinvukusic; things are all clear now :) Geert ——— Marc Lang catches the eye by breaking world blindfold record — When Miguel Najdorf played 45 chess games simultaneously blindfold in São Paulo, Brazil, in 1947 the exhibition took over 23 hours, including an interval for Najdorf to change his perspiration-soaked shirt and rest his eyes. Later the Hungarian Janos Flesch played 52 games without sight of the board, but his claim unravelled because many opponents resigned after a few moves, and it seemed that Najdorf's performance would never be approached. But last month a little-known 41-year-old 2300-rated German chess master, Marc Lang, toppled the record with 46 games in 21 hours. In previous years Lang set a German record, then broke George Koltanowski's historic European mark of 34 games played at ...
Posted by sharpgate kttstudios.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? ——— The World Chess Hall of Fame — The World Chess Hall of Fame celebrated the 10th anniversary this month in a new location in St. Louis, Missouri. The history of the Hall and portraits of inducted chess players are available on the impressive web site. When it first opened in Miami in December 2001, I was inducted there together with five great chess players: the unofficial world chess champion Paul Morphy (1837-1884) and the official ones such as William Steinitz (1836-1900), Emanuel Lasker (1868-1941), José Raúl Capablanca (1888-1942) and Robert James Fischer (1943-2008). I shared the same birth city, Prague, with Steinitz and as fate would have it, we both ended up in America. "The decision of Lubomir Kavalek not to return home from a foreign chess ...
Posted by chessnovice kttstudios.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. ——— 2011 Year in Review — And what a year it has been! 2011 started with St. Louis’ own Hikaru Nakamura winning the 2011 Tata Steel chess tournament in Wijk aan Zee, Holland, against the world’s best chess players. It was the biggest tournament victory for an American since Bobby Fischer, and his performance catapulted him to No. 7 in the world chess rankings. Although he has experienced some ups and downs this year, Hikaru is currently holding onto the No. 10 spot in the world and is looking forward to an exciting 2012. World No. 1 Magnus Carlsen, who turned 21 in December, proved he is worthy of his top spot as he turned in solid performance after solid performance all year. He is steadily climbing toward Gary Kasparov’s peak rating of 2851 and ...
Posted by lighttotheright kttstudios.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 kttstudios.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 kttstudios.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 kttstudios.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 kttstudios.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.
