John - in view of your concern with ratings inflation, I think that we should know the truth - and I think that you're the man with the passion and enthusiasm to find out. To do this, we need something that plays at a consistent level. A chess computer will do nicely! Here are the steps you'll have to carry out (with 100% impartiality): * obtain a recent sample of games by players of various rating levels * get a chess computer to rate the moves (circa 5 mins per move analysis may suffice) * find out if there's a good correlation between player elo rating and average chess computer move rating * if the answer's "no" - stop the experiment. If the answer's "yes", continue * take a sample of games from 30 years ago, and analyse them under the same conditions * see whether the results match the modern results obtained earlier * post the overall results of your experiment here If the correlation is good, we will then have an answer. -g On June 19, 2001 at 17:20:35, John Hatcher wrote: >Dann, > >At the risk of whipping a dead horse - > >IF it is true that there has been rating inflation over the past 30 years >(perhaps as much as 100 points) then a player rated 2400+ in 1971 would be rated >2500+ in 2001.
