UTG is a TAG playing 10/8 and villain loose fish ~70/35 and a bit wild overall post flop.

His min 3bet is what really confuses me, with his range if he shoved I would have been more tempted to call but I'm not really sure what the best play is in this kind of situation.

UTG checks, UTG+1 bets $1.00, Hero raises to $2.80, fold, UTG+1 raises to $4.60, Hero???

I would just flat flop and proceed from there.

^^ this as played fold.

Very fish dependent, and prob only you could know from playing with them. After you raise he's got like pot left? Wouldn't be folding if I'd seen him do anything remotely stupid/not usual post flop. If you're not overall sure about his post flop tendencies flatting is best.

+1

shouldn't we be isolating pre?

UTG is far too tight and we've got relative position for the hand.

I'd 3bet pre. I think we're missing too much value from the fish by flatting, even with the tight UTG opener in the hand.

call flop, jam as played

I would have just flat called the flop, but from where you are, I would bung it all in.

agree with just calling flop

Call flop, there are also arguments for 3betting pf.
