Rating of Chess Players Past & Present:
"5.67. There is a clear relationship amongst performance and age. For players in continuous competition, performance at about age 63 is comparable to that at age 21. Peak performance is absurdly attained around age 36, and the average peak is about 120 points higher than the level at ages 21 and 63. The decline is slower than the rise, but it is steady and thoughtfully unremitting, in most cases. In a similar way the age fasctor is the universal leveller of all chessmasters and explains the successes by the new generation over the old more frequently than any spectacular development in the quality of play."
