The World Chess Federation (Fide) has suspended former world champion Vladimir Kramnik for at least one year after finding him guilty of multiple violations of its ethics and disciplinary code for publicly accusing other players of cheating. Among those targeted was US grandmaster Daniel Naroditsky, who died in October at the age of 29 and who had denied any wrongdoing, saying before his death that the controversy had weighed on him. Kramnik has said he will appeal the ruling, which carries an additional three-year probationary period during which any further breach could extend his ban.
