I don't think there's not going to be any binary or absolute outcome in this - if Niemann is actually (formally) accused of cheating. Best thing would probably be some statistical analysis, and some likelihood of the moves made. And in the end, someone will probably conclude that there's a x% chance that cheating occurred. With that said - at this level, I don't know how you differentiate true outlier moves, from the player just being incredibly apt at the game? I've heard that one way of identifying algorithmic / computer programs, is that the moves can extremely weird compared to what a human player would have done.
