[edit] Comparing chess players from different time periods

What systems exist for comparing two chess players whose careers did not overlap? NeonMerlin 22:33, 22 July 2007 (UTC)

We even have an article entitled Comparing top chess players throughout history! One system is the Elo rating system. For issues in using this for comparing the strengths of non-contemporaneous players, see also the section Ratings inflation and deflation in that article. Another system is Chessmetrics.  --Lambiam 04:19, 23 July 2007 (UTC)
