Norwegian chess world champion Magnus Carlsen and online platform Chess.com have urged a US federal court to toss out a libel suit brought against them by US teenage grandmaster Hans Niemann, who Carlsen has accused of cheating.
Chess.com executive Daniel Rensch and Carlsen said in their filings that Niemann was an "admitted" cheat who failed to identify any defamatory statements by them in his lawsuit in US District Court in Missouri.
