Both villains are unknown. I guess MP is just a fish. I've got a few questions here. After I isolated them, CO makes a 3bet (4bet?). Not sure what to do??? Is he capable of doing that with AA, KK? Why wouldn't he isolate MP him/herself? My next question is, what should I be doing on both of this streets? Fold, or call this m-fker down?
