Former world chess champion Vladimir Kramnik has been suspended from international chess competitions for one year after the International Chess Federation (FIDE) found he violated its ethics and disciplinary codes by making public accusations of cheating against fellow players.

FIDE announced the decision following an investigation into complaints over statements made by the 51-year-old Russian grandmaster about several top players, including Czech grandmaster David Navara and American grandmaster Daniel Naroditsky.

According to FIDE’s Ethics and Disciplinary Commission, Kramnik breached the federation’s rules on dignity, respectful treatment, bullying and cyberbullying, psychological abuse, and his responsibilities as a role model. The commission also found that he failed to cooperate with a Fair Play Commission investigation and made false or unjustified public accusations.

The commission imposed a two-year worldwide ban from participating in FIDE competitions or serving in official chess functions. However, the second year has been suspended for a three-year probationary period, meaning Kramnik will serve an active one-year suspension provided he commits no further violations. He was also ordered to complete 12 months of unpaid service benefiting the chess community.

FIDE said combating cheating remains one of its highest priorities but stressed that allegations must be handled through the federation’s confidential reporting procedures and supported by evidence rather than made publicly. The governing body said publicly linking identifiable players to cheating without proof exposed them to “unjustified reputational and psychological harm.” Among those affected was Czech grandmaster David Navara, who said Kramnik’s accusations contributed to suicidal thoughts.

American grandmaster Daniel Naroditsky also spoke publicly about the impact of the allegations before his death in October 2025.

During a livestream, he said the accusations made him feel that any future success would be viewed with suspicion. Authorities later ruled that Naroditsky died from accidental poisoning involving multiple substances.

Responding to the ruling, Kramnik said he intends to appeal. In a statement posted on social media, the former world champion said he was “absolutely confident” the decision would be overturned and vowed to pursue all available legal avenues to restore both justice and his reputation.

Kramnik held the World Chess Championship title from 2000 to 2007 and is regarded as one of the strongest players of his generation. His suspension bars him from competing in FIDE world championship events and carrying out official functions during the active period of the sanction.
