EDIT:
Ok this is interesting. If we do FGS1 we get
UTG 22.8%, 22+ A2s+ A7o+ K8s+ KTo+ Q9s+ QJo J9s+ T9s
UTG+2 7.1%, 88+ ATs+ AJo+
CO 3.5%, TT+ AKs AKo
then FGS2 says
UTG 25.0%, 22+ A2s+ A7o+ A5o K6s+ KTo+ Q9s+ QTo+ J9s+ T9s
UTG+2 7.9%, 77+ ATs+ AJo+
CO 3.9%, 99+ AKs AKo
It would really start to make a difference if CO got wide enough that he started to have aces lower than AK
I need to buy a supercomputer now so I can do FGS 100
