Tracking 23 Top Players at Twelve Super-Tournaments. Each entry gives: - player's current rating - player's score and +/- - player's IPR (error bars omitted, typically +- 200, and +- 50-100 overall) - difference with IPR of opponents's play. Overall score differentials, IPRs, and IPR-differences are at far left. Note the correspondence between the +/- scores and the +/- IPR differences. This appears to be tighter than the correspondence between IPR and rating (pre- event), and even that between IPR and the Tournament Performance Rating (which can be calculated from the tournament average rating, the player's rating, and the +/- score). Some exceptional figures are marked with ! --- for instance, Carlsen is certainly playing like his rating, Adams' resurgence is no accident, and the Moscow Tal Memorial was played to high accuracy. The IPR still measures primarily accuracy, to the possible disadvantage of tactical players, though the IPR difference compensates for the greater risk they generate. Comparisons of the 23 top players and the other players in these events are at the bottom. (An earlier version of this file missed the last 3 rounds of the Tal Memorial.)
