In 1963, Botvinnik founded his own school within the Soviet coaching system, and its graduates include world champions Anatoly Karpov, Garry Kasparov and Vladimir Kramnik, and other top-class players such as Alexei Shirov, Vladimir Akopian and Jaan Ehlvest. Botvinnik was not an infallible spotter of chess talent: although he said of the 11-year-old Kasparov, "The future of chess lies in the hands of this young man", he said on first seeing Karpov, "The boy doesn't have a clue about chess, and there's no future at all for him in this profession." But Karpov recounts fondly his youthful memories of the Botvinnik school and credits Botvinnik's training, especially the homework he assigned, with a marked improvement in his own play. Kasparov presents Botvinnik almost as a kind of father figure, going some way towards balancing the common public perception of Botvinnik as dour and aloof; and Kasparov inherited Botvinnik's emphasis on preparation, research and innovation. Botvinnik was still playing a major teaching role in his late 70s, when Kramnik entered the school, and made a favorable impression on his pupil.
