So Kramnik, being a chess player and not a statistician, invented various methods of "detecting" cheating which seemed convincing for for a layman but questionable mathematically.
Then he started attacking Daniel, Hikaru and some other players online. This all led to pretty tragic consequences.
Kramnik still believes that he's in the right.
The only good thing out of this is numerous funny videos by chess players trying to figure out intricacies of statistics and math.
A lot of people imagine chess players to he smart, but there's a video of asking grandmasters very simple (imho) general knowledge questions that they did absolutely abysmally at. It's probably safe to assume that someone who is really good at chess is actually bad at anything that isn't chess
Naroditsky played a match against Magnus that he streamed where it ended (this a 1+0 time control; yes you can cheat in bullet but it's clear he wasn't) in a 40-40 tie, this after he lost the first game from being distracted getting his stream set up properly
He was one of the world's best bullet and blitz players, it was obvious he was never cheating. Kramnik was apparently one of his heroes. It was despicable behavior
Not as a defense of Kramnik's behavior, but Naroditsky's death was determined not likely to be suicide:
probable cardiac arrhythmia tied to systemic sarcoidosis, with methamphetamine/kratom as contributing factors.
