Jim talks with Grandmaster chess player and philosopher Jonathan Rowson about the recent drama between Magnus Carlsen and Hans Niemann in the Champions Chess Tour. They discuss Rowson's chess background, the bare facts of the kerfuffle, Niemann's persona & career trajectory, present evidence for whether Niemann cheated & the reasonable odds that he won fairly, how Carlsen might know whether he cheated, Carlsen's special information access, theories about how cheating in chess might be accomplished, the risk of paranoia in chess & chess culture, and much more.
