Fyodor Ivanovich Dus Chotimirksy (1879-1965) was a Russian International Master (1950). In 1909 he defeated the eventual winners Emanuel Lasker and Akiba Rubinstein at St. Petersburg, but took 13th place. He claimed he was Alekhine’s first chess teacher, in 1900. He played in five Soviet Chess Championships. He once took a move back against David Bronstein in a tournament as spectators watched his game. In response to the crowd and the tournament director who tried to intervene, he shouted, “Hey, I just made a bad move and now I an changing it to a good one. To hell with the rules, this is chess.” The game continued as nothing happened. Dus-Chotimirisky may have been the person who coined the name “Dragon Variation” of the Sicilian Defense.
