Sorry, no hand history, but it is pretty close from memory. Turn and river can be a bit off, I remember that they were 2 blanks.

OP seems to be TAG may be even rockish 18/6/4 (about 300 hands), he is on 2 of my tables. He was up on both of them when I sat down (there were some loose fish). He played back at me once when he floated my CB in position and bet the turn when I checked: I folded. He also made some lay downs before, when I pressed him hard. I don't know if he is aware of that, but I don't call his raises with hands lke AQ, AJ, I have something like PP or SC when he is the raiser and I am in the pot with him. I mean I had good hands or draws when I raised him before. He probably consideres me a bit loose 30/11/2.

Effective stacks are about 350, if it were only 200 I would push the turn.
Other lines, ideas?

Preflop: I have UTG and raise to 7, Villian calls in BB.
Flop (15):
BB bets 15, I call.
Turn (45):
BB bets 40, I call.
River (125):
BB bets 100, I call.

On flop I thought that OP had a draw, set, QQ, JJ , I didn't want to raise as he could push (3 bets) with draws, sets and fold QQ, JJ. (I think that he would rer preflop with AA, probably with QQ and JJ too).

On the turn I suspected a draw or a set (I agree with Cooper that he would likely check QQ or JJ), but I was unsure what he would do with a draw if I raise here. We were deep enough, so that if he pushes I would be in a tough spot.

On the river I was unsure as I was beating only a bluff at this point, but I've never seen an opponent who would lead full pot with set on the flop and the turn, so I decided that he was likely bluffing.

He showed for a missed flush draw.
