The mother of former grandmaster chess player Daniel Naroditsky has publicly addressed her son’s passing for the first time, revealing that he struggled with online claims accusing him and others of using computer “chess engines” to cheat.

Naroditsky, who gained prominence as a leading figure in modern chess through his substantial YouTube and Twitch followings, was discovered dead on Sunday in Charlotte, North Carolina.

He was found on his couch by fellow grandmaster Oleksandr Bortnyk, who visited after losing contact, as reported by the Daily Mail.

In a recent chess livestream, U.S. grandmaster Daniel Naroditsky appeared as an influential figure in the community. His untimely death in Charlotte, N.C., has led to an ongoing investigation, with police awaiting toxicology reports while the International Chess Federation examines harassment allegations involving his Russian rival.

“Daniel valued his dignity and reputation as a chess player above all else,” said his mother, Elena Naroditsky. “An ex-world champion was accusing him of being a cheater.”

Russian grandmaster Vladimir Kramnik, who held the world title for several years in the early 2000s, began accusing Naroditsky of cheating in online chess last October. He continued to share his suspicions on social media over the past year without providing substantial evidence.

Naroditsky, who at 18 became a grandmaster, the highest title in chess aside from world chess champion, had denied the cheating allegations and accused Kramnik of trying to ruin his life.

“Daniel tried to defend himself so much. The whole world was on Daniel’s side,” Naroditsky’s mother said. “He played more and did more and more because he was trying to prove that he’s not what he was accused of.”

Meanwhile, Arkady Dvorkovich, the president of FIDE, the International Chess Federation, referred Kramnik’s statements to the ethics and disciplinary commission for review, promising “appropriate action” if harassment or bullying were found.

In a new interview with Russian broadcaster Match TV, Kramnik said he intends to file a lawsuit against FIDE, claiming the organization misrepresented his remarks about Naroditsky following the American player’s death.

“I did not say anything bad about him, and I demand to confirm these ‘accusations’ of FIDE … with an actual quote. Otherwise, it may become the subject of legal proceedings,” Kramnik said, per excerpts of the interview he posted to his X account.

Police told the Daily Mail they are awaiting toxicology results to determine what was in Naroditsky’s system. Investigators said there were no signs of foul play and that suicide or accidental overdose are among the possibilities being examined.

“It’s a tragedy. He was my dearest son. He was 29,” Naroditsky’s mother said. “Daniel was such a life. He was so brilliant, so incredibly kind and loving, thoughtful, giving, inspiring.”

Naroditsky was a chess prodigy-turned-grandmaster who helped bring the centuries-old game into the digital age through livestreams and online lessons. He won the Under-12 world championship before becoming a grandmaster at 18 — the game’s highest title short of world champion.

Fellow grandmaster Bortnyk later described in a Twitch livestream that he and a friend entered the apartment after noticing Naroditsky’s television was still on, and that he discovered his friend’s lifeless body.

It came after Naroditsky’s final live stream on Friday in which he returned after what he said was a “creative break.”

“You thought I was gone forever, but little do you know I’m back and better than ever.”

It comes as several grandmasters, including Hikaru Nakamura and Nihal Sarin, have called out Kramnik’s conduct, saying the Russian pro had harassed Naroditsky and tried to destroy his reputation.
