Chess Champs Score by Age

Chessmetrics (http://db.chessmetrics.com/...)
Today is International Chess Day; in honor of the game and its history this graph shows six of the highest ranking chess masters' scores over the length of their career. Each color on the graph represents an individual player: Fischer, Lasker, Kasparov, Steinitz, Botvinnik, and Alekhine.
The scoring system,
Chessmetrics Performance Rating, is based on the ELO rating system and measures the relative strength of one particular chess player, based upon the historical results (i.e., win, lose, or draw) of that player's serious games against other players. Each of these players were ranked number one for 9 or more years. Emanuel Lasker held the number 1 rank for just over 24 years; he also won the most world championships. Kasparov held the number 1 rank position for 21 years; Steinitz, 14 years; Botvinnik and Alekhine, each 10 years; and Fischer, 9 years.
Four of the six players (Fischer, Kasparov, Botvinnik, and Alekhine) began playing competitively before they were 20 years old; the youngest was Bobby Fischer, who was only 13 when he began his career. Overall, players tended to peak around their late twenties and early thirties. However, all players who continued to play after the age of 50 rapidly declined in rank. As a recreational activity, chess ranks in the top 30 things Americans enjoy doing with their leisure time.
