CO raises to $0.20, fold,
Hero raises to $0.80, fold,

CO if unknown, not fullstacked so fish/recreational.
A8s is too weak to fold so I isolate as default here.
I give him aproximate preflop calling range vs my 3bet:
22+, A2s+, K9s+, Q9s+, JTs, A8o+, KTo+, QTo+, JTo
I think this also should be about the same at non zoom.
what do you think - is this ok, or too loose? On average I mean.
It is important to assume correclty because based on it we do actions on flop.
Btw actually checked with equilab and my A8s only has 47% eq vs this range, so not so good spot, but assumeing he will have to fold a lot post flop, I think its good.
WE might think about that he has position so he can be wide but for the fish position does not matter that much, so even if we are BTN his range should be similar.
