The Chess Strength of Mir Sultan Khan

In his brief but meteoric career, Sultan Khan rose to the top of the chess world, playing on even terms with the world's best players. By Arpad Elo's calculation, his playing strength during his five-year peak was equivalent to an Elo rating of 2530.

In 1950, when FIDE first awarded the titles of International Grandmaster and International Master, Sultan Khan had not played for 15 years. Although FIDE awarded titles to some long-retired players who had distinguished careers earlier in their lives, such as Rubinstein and Carlos Torre, it never awarded any title to Sultan Khan.

Hooper and Whyld write of him:

"When Sultan Khan first travelled to Europe his English was so rudimentary that he needed an interpreter. Unable to read or write, he never studied any books on the game, and he was put into the hands of trainers who were also his rivals in play. He never mastered openings which, by nature empirical, cannot be learned by the application of common sense alone. Under these adverse circumstances, and having known international chess for a mere seven years, only half of which was spent in Europe, Sultan Khan nevertheless had few peers in the middlegame, was among the world's best two or three endgame players, and one of the world's best ten players. This achievement brought admiration from Capablanca who called him a genius, an accolade he rarely bestowed."
