Far more matches are won by the side that is luckiest on the day than is generally realised. The shorter the match, the greater the mean variation in luck. If one side has a Snowie luck advantage of +5, it is almost impossible to overcome this with good play and the majority of short matches are decided by the dice. Although bots appear to be "luckier", they do not on average have better luck than humans. The appearance of luck is the outcome of their better play; strong play creates more good rolls next turn than weak play.
Watching bots play each other is no more or less interesting than watching two strong human players, in fact for learning purposes, I find all matches to be equally interesting, even if the protagonists play quite badly. I am not sure what the bot tourney is supposed to show.
No lews, bots roll the same number of doubles as humans, because like humans they get what the server gives them.
