I have a bluff catcher 600NL

Villain is the loosest good reg there is. He will be betting the flop and turn with most of his range, but I think he has a very good sense of when to give up. He views me as tight/solid I guess. 3betting pre and getting this is in is +EV fwiw. He has $352 left after the bet.

Okay..I don't play this high and I'm a bit of a donk/tagfish but I'll give it a shot:

62% pot, 84% pot (on the 'scare card'), 74% pot. This is what stood out to me at first.

His turn bet sizing is weird to me (big jump compared to the flop size) is this just standard though for him? I mean, it doesn't seem like he's really planning out his hand here with the weird jump in bet sizing. Your range is probably perceived as like 66-88, TT-JJ for the most part. 99 is only 1 combo so I doubt he's worrying about that. It doesn't seem like he'd ever have quads or a boat here given his weird bet sizing though...so I'm calling mostly because his sizing on the turn and the fact that I don't think he's going to play Qx like this given your solid image. In fact, I would pressume he would think about his bet sizing more with 1 pair like hands to try and maximize value (or maybe this is his way of doing so). I think we must be good here alot and see a busted flush draw or something of that nature often enough (I'm guessing he's opening a fair amount of SC's/suited bways from EP that will be barreling this board).

Because he is so loose is what scares me. His range is so wide, easily have a 5 in his hand some kind of Qw flush draw combo could have air maybe a 9. I fold..

Are you thinking about shoving? I definitely do not like shoving, it just doesn't make a lot of sense since you won't be calling this open with SCs and so many players yet to act (I presume...?) I think I would call this if he's that loose given the number of missed draws etc. It's probably really close between calling and folding and I'd just go based on dynamic and how nitty he views you as..
