Botvinnik was antisemitic, having no tolerance for Judaism, discriminating against Samuel Reshevsky who was an Orthodox Jew who kept the 7th day Sabbath. Botvinnik and Soviet players often referred to accommodations for time off to observe the Jewish Sabbath as "the Reshevsky Problem." Fischer too, who joined a Protestant Xtian sect, never worshiped in the religion of Judaism. Botvinnik, like the Soviet regime were avowed Atheist.
