I know some were worried about the strength of the bot in playing this out so I jacked up the settings and expanded the move filter. It's only 324 trials and not near stat. sig. but what it shows us for certain is that 15/11 is a clear error. I think a lot of people would have played this in order to better cover and make our bar point.
The second rollout is normal every day settings and cuts down on the variance a bit fwiw.
