Chess blog for latest news and trivia (c) Alexandra Kosteniuk, 2011
Hello everyone,
Several different research ideas have been forthcoming about the accuracy and inaccuracy of the Elo rating system. Here is another very interesting and detailed article on www.chessbase.com by Elmer Dumlao Sangalang. He says:
… the Elo Rating of an individual player is not a mathematically precise figure. It is statistically derived with an accuracy in direct correlation to the amount of data (game results) on which it is based. A measurement based on the standard 30 games provides a rating that is 95% probable to be within plus or minus 100 Elo points of its true value. That’s the reason why it is not a certainty that the higher-rated player will always beat his lower-rated opponent. Take this simplistic illustration: Player A rated Elo 2600 plays with Player B rated Elo 2500. The true strength of A lies in the range of 2500 – 2700 while that of B is in the range of 2400 – 2600. If A plays languidly at 2550 while B plays inspired chess at 2550, we will have an even match and the game should result in a draw!
The invention and employment of the Elo rating system may be the best, but not the perfect, thing that ever happened to chess playing and organizing. The late Professor Arpad E. Elo expressed strong sentiments over the inordinate importance being attributed to the rating. He regretted that the Elo Rating System contributed greatly to the prevailing opinion that regards chess as first and foremost a sport. As a result, the chessplayer’s Elo Rating has been overvalued in significance by top-rank players and organizers of major and prestigious chess competitions. And for that matter, even by FIDE, itself.
