In Response To: ELO in chess (Nack Ballard)
Thanks Nack for your comments. I am familiar with the expected scoring percentages for both 100 and 200 ELO differences which you mentioned. In my chess infancy I read the book, The Ratings of Chessplayers, Past and Present by Arpad Elo.
I agree that a 100 or 200 ELO difference should be the same regardless of the levels of the two players involved though in the short term it doesn't seem to be so. I wish there were more 2900 chessplayers to provide a more reliable sample.
Perhaps my earlier comments should have been about the likelihood of a draw between uneven matched players and the inconsistent play among the players at the lower levels. Magnus Carlsen may not lose as often to a 2700 player but he may not win as often as a 1700 player against a 1500 player. Of course this is all speculation on my part.
