Elo over time

Every player gets one rating per year, fitted to all games of about 2,000 players at once, with white advantage, draw rates by era and the typical development by age. From it: latest and peak Elo, best five years, performance in the peak period, career average, years at #1 / in the top 5 / top 10, peak and elite periods, rating at a given age.

Click a rating cell for the player's curve. Select players first to draw them alongside.

Career rating from these results

One number per player for the whole career (maximum likelihood), for any group of players, on the same scale as Elo over time. Cochrane's 1821–23 games are rated as a separate early-career player.
