Message: The FIDE system orders chess players who participate in international OTB (over-the-board) games under strict tournament rules. GK measures those who play chess by internet on this particular site. The very fact that the systems were instituted at different times - roughly 30 years' difference - is alone sufficient to create a significant difference in the numbers you are looking at. I can think of all sorts of other reasons for such differences. Bear in mind, as I've said elsewhere, the rating number has no meaning in itself. I seriously doubt Professor Elo himself would say anything different. It is where your rating stands on the list that is significant, and the size of the difference between your rating and another's (even that should be taken 'cum grano salo'!). Of course, the whole thing is built on the ongoing history of all the game outcomes (W, D, L, and who played whom) since the rating system in question was instituted (FIDE in the 1960s, GK c.2000). Personally, I have my doubts about the ELO system, about the claims made for it, the uses to which it is put, and the way it is interpreted. I'm pretty certain it isn't really robust enough mathematically to update one's rating game by game as it now does (the original FIDE system didn't). But as also has been said elsewhere, it's probably the best we can hope for. Cheers, Ion |
Chess news: Magnus Carlsen Survives on His Wits -- One of the reasons that Garry Kasparov was the world’s dominant chess player from the late 1980s through the ’90s was that he was better prepared than his competitors. He spent an enormous amount of time researching chess openings for new ideas to spring on his opponents, or he paid others to do it for him. Magnus Carlsen, currently the world’s top-ranked chess player, is beginning to be as dominant as Kasparov was, but it is not because of his preparation. He has described himself as a bit lazy, and so rather than play the most popular chess openings, which everyone has studied, he often chooses systems, particularly as White, that do not yield any advantage. Carlsen wants to ... Vasily Smyslov: the master of incisive calculation -- How did the late Russian chess grandmaster deal with this situation? The life of a professional chess player is mentally and physically challenging. After the age of 40, for most professionals, there is a seemingly inevitable slide down the chess rankings. Garry Kasparov retired at 42, rated No 1 in the world, but I suspect he felt that the chasing pack was getting too close. That's why Vassily Smyslov's chess career was so remarkable. Smyslov, who died earlier this year, became world chess champion in 1957 at the age of 36, but continued playing at the highest levels, qualifying for the final of the world chess championship at the age of 63. This was the victory that got him ... Laznicka Wins World Open -- The World Open is without doubt one of the toughest and most competitive chess tournaments of the year. It regularly attracts a world-class field and it has an impressive roster of previous winners (or those who tied for first). This year’s tournament, which ended Monday, was no different. There were three dozen chess grandmasters from around the world and numerous other international masters and masters. Though certainly not an unknown player, this year’s winner, Viktor Laznicka of the Czech Republic, was a bit of a surprise as he was not among the better-known chess grandmasters at the start. But he raced out to a one point lead by winning his first six games, including ... | |
