text: Online chess Kramnik has been active on the online chess platform Chess.com where he frequently plays blitz games and participates in tournaments. He regularly participates in the Titled Tuesday tournament and has expressed concerns over cheating in online chess, including numerous high-profile cases. In November 2023, Kramnik made a statement on his Chess.com profile purportedly insinuating that an unnamed high-level player was cheating. Hikaru Nakamura believed this post was targeted towards him, and he responded with a statement on X reading: "Vladimir appears to be referencing my record...is he really accusing me of cheating??? ." Nakamura also expressed disappointment with Ian Nepomniachtchi for reposting Kramnik's claims. In December 2023, Kramnik's poor conduct prompted online chess website chess.com to close his blog and mute his account. After he accused multiple more players of cheating in the time after his first major accusation, Kramnik himself was found to be violating chess.com's terms of service and banned from prize tournaments after he was caught playing on Denis Khismatullin’s account. Kramnik then took to X to blame the whistleblower, IM Matvey Galchenko, calling him, in Russian, "a YouTuber posing as a chess player" and to blame him for the fact he would no longer be streaming Titled Tuesday.
