Is 9 high flushdraw with a gutshot too weak to call a second barrel here?
----------------If it that's the case, is this good hand to turn into a bluff here and x/r turn?

IMO x/r>x/c in this spot. Im not sure but imo we don't have enough equity for x/c.
Can we donk this turn for a bluf?

this is very good hand to check raise if you need to do it for balance, but I dont think its a good idea vs fish, fish doesn't barrel that much and they will also call wider so check raise will be much worse than c/c vs fish imo, so c/c.

So are you saying we dont need bluffin range here at all vs fish? I agree with this because he doesn't exploit us by adjsuting and folding more I guess.

I x/folded this hand because I was not sure if 9high flush draw was good enough to call the second street. If we didn't have also a gutshot, then it is a fold right?

You dont need to bluff any hand unless its best from all other options also its close i think, probably close call, so folding is not that bad

If we dont bluff any hands then we dont get so much value when we actually have a hand

I think it's a better call vs the population since they will have bad ranges and play bad on rivers. So in theory i would guess check/raise > check/call ~= check/fold but vs the population I think check/call > check/raise ~= check/fold

Why do you think this is true readless vs. a fish?

It is not but this is played readless and villain is likely not a fish. Then I try to play near GTO game (but in many spots I have no idea how gto plays there)
