Okay, so continuing on, this situation came up:
We are both 3 away, so I get that our match equity at this point is 50/50. I've brought up the XG cube analysis window, and it seems to indicate that in this situation the "too good to double" option for red kicks in at 91%, yet this seems to contradict the analysis panel, which shows red's winning chances as 69%, yet it still suggests the situation is too good to double.
I think I am completely misunderstanding something here, any help appreciated!
