The international governing body for chess suspends former world champion Vladimir Kramnik for at least a year after he accuses other players of cheating without what the federation considers adequate evidence. Multiple outlets report that the suspension follows Kramnik’s public allegations, including claims involving grandmasters David Navara and Daniel Naroditsky. The federation cites violations of its ethics code, saying Kramnik makes cheating accusations publicly without adequate evidentiary support.

One report says Kramnik had continued sharing suspicions on social media after raising the allegations last year. Daniel Naroditsky, who died last year at age 29, denies the accusations, according to the coverage. Kramnik tells outlets he plans to appeal the suspension and expresses confidence that the decision will be overturned. The reports describe a process focused on compliance with the chess ethics and conduct rules rather than any confirmed cheating findings.

Overall, the dispute centers on whether Kramnik’s public claims meet the standards required for such allegations under federation rules and the resulting disciplinary action for ethical violations.
