The FIDE Ethics and Disciplinary Commission (EDC) has banned GM Sergey Karjakin for six months from participating as a player in any FIDE rated chess competition. The 32-year-old Russian grandmaster, who is a fierce supporter of Russian president Vladimir Putin, was punished for his recent statements on social media and will be missing out on this year's FIDE Candidates Tournament.
