BB is pretty unkown. So far he seems tight.
UTG is unkown too. But has play 3 out of 4 hands so far and openlimped UTG. Prolly a fish.

Pre is somewhat close to borderline, right?
OTF I was alrdy not 100% sure about the best line. I thought about checking b/c seeing a free turn isn't terrible, but I guess I have too good of a hand for that. Therefore I bet out. I guess I would've folded if BB repopped me. If UTG raised I'd be pretty lost.
OTT. I think BBs range is bare NFD, wraps, sometimes top2.
UTGs range is prolly wider. More fd's, oesd, wraps, TP+gutter etc.
Vs those ranges the turn is actually good for my actual hand and good for my perceived range, right? I have 33% vs bare Q9 now.
If I bet OTT I think BBs is fold quite a bit (mainly straightdraws).
Tough to say how big of a fish UTG so I don't know if he'd fold bad bare fd's or bare oesd. If he called and BB folded I'd prolly shove a spade and T and bluffcatch on a lot of blank rivers.

Pre is fine to "iso" the fish I guess

Think betting flop is fine. With both guys to act behind you, you should know whether it's a b/f or b/c depending on the action.

I b/c turn and barrel a bunch of rivers if I get just called

I'd b/c something like 30 although I'm probably not barreling a lot of rivers because Qx+ can often times talk themselves into a call when everything misses on the river and we do have a bit of showdown equity vs other draws. Pre doesn't seem that marginal

I like pre. Turn bet sizing should be so we can shove a psb on blank rivers, but we are too shallow for that, so something like 25 would leave about 60 effective and an $87 pot. That assumes BB is the caller. If both call, just probably give up blank rivers.

If raised, call turn.
