I've only been back playing poker for a couple months after an extended break away, so I tend to default to some calling station tendencies. I'm trying to find better spots to raise without raising into the nuts (which is something I'm currently good at doing).

6 max 25NL on Bodog
Full stacks.

Dealt: QcJd

Preflop: 2 folds, CO raises to 0.85, 2 folds. Hero calls

--Mental note I had on CO was that he was decent. Hadn't done anything out of line.

Flop: Js 2h td

Hero checks, CO bets 1.25, Hero calls

--Think this is pretty standard? I've got the Q and it's a rainbow flop.

Turn: Qh

Hero checks, CO bets 3.25, Hero calls

-- I struggled here. It's basically a pot size bet. I don't think he plays AK this way, but he's definitely repping the higher end of his range.
--Is it worth going for a raise here? I haven't done the math to figure out whether it makes sense or not, but in the moment, I thought about shoving on him.

River: 5d

Hero checks, CO bets 8.50, Hero throws up a little and hits the extra time button.

--I showed strength on the turn and he pots it again.

Thoughts?
