Federal judge dismisses chess prodigy's $100 million lawsuit against world champion and online platform

Hans Niemann's lawsuit claiming defamation and antitrust violations was dismissed, though he can refile some claims in state court.
Niemann sued Magnus Carlsen and Chess.com after Carlsen accused him of cheating following an upset victory, and Chess.com banned him for alleged past cheating.
The judge rejected Niemann's antitrust claims and bid for damages but allowed him to pursue defamation and libel claims in state court.
Carlsen and Chess.com's lawyers welcomed the dismissal of Niemann's "strategic litigation" aiming for an "underserved windfall."
Niemann admits to cheating as a teen but denies wrongdoing in the Sinquefield Cup or matches with prize money, claiming Carlsen and Chess.com conspired to destroy his career.
