A lawsuit filed by former world chess champion Vladimir Kramnik has rocked the sport, divided opinions and forced the International Chess Federation (FIDE) to intervene. The 14th undisputed World Chess Champion, Kramnik, 50, has filed a civil defamation lawsuit against Czech Grandmaster David Navara, Chess.com and news outlet Chessdom in Geneva.
Kramnik filed the lawsuit after public clashes with the defendants over cheating allegations.
Why Kramnik filed lawsuit against Navara, Chess.com
The controversy began when Kramnik suggested that Navara may have cheated during online games, however, he did not present any hard proof. In response, Navara published an open letter titled Because We Care on Chess.com on May 23, 2025. In the letter, Navara accused Vladimir Kramnik of spreading toxic commentary and causing him significant psychological harm.
Russia’s Kramnik has denied the allegations, calling them false and claiming they were never corrected despite multiple requests.
The day after the letter’s publication, Chessdom.com published a series of articles that echoed Navara’s accusations and further depicted Kramnik as hostile and provocative.
In his legal complaint, Kramnik highlights a podcast by New in Chess, alleging that some of Navara’s original statements were later edited without acknowledgment. However, no public correction or clarification was issued. Kramnik claims the resulting media fallout led to threats against him and the cancellation of at least two professional commitments.
Aronian asks Kramnik to withdraw lawsuit
Meanwhile, American chess Grandmaster and former world rapid and blitz champion, Levon Aronian, recently asked Kramnik to withdraw his lawsuit as it is based on online analysis that “doesn’t make sense”.
“We are a family," Aronian wrote on X. “We can’t go on suing or threatening each other for some weird online analysis that in most cases doesn’t make sense."
“Let us start from a fresh page."
FIDE condemns Kramnik’s legal action
The FIDE reacted to Kramnik’s legal action on Sunday, announcing the formation of a task force to evaluate anti-cheating methods proposed by Kramnik. They also invited him to present his ideas for review.
However, FIDE condemned the legal action by Kramnik against Navara, who was described as “paragon of a fair play” by the governing body in its statement, as it asked the former Russian player to withdraw the lawsuit.
“At the same time, we are gravely concerned that the way Mr. Kramnik presents his points brings a lot of harm to the chess community,” FIDE’s statement read. “Mr. Kramnik must recognize, that it is not just his opinion or questions – it is a very clear narrative, and coming from the former World Champion it could be ruinous for the careers and a very well-being of certain players.
“The current discourse has significantly affected such a respected member of the chess community as GM David Navara and has now led to a defamation lawsuit being filed by GM Kramnik against GM Navara.
“We wish to emphasize once again that throughout his chess career, GM Navara has earned an unquestionable reputation as a paragon of a fair play. The chess community is well aware that David is a person of a great sensitivity and integrity, particularly vulnerable to any implication of unfair play.”
