More value from bottom set? 2-5NL

[spyu]

Was playing 2-5NL last night at the RIO. 500max buy-in
7 handed. I had about 650 villain covers. Villain seems to be a regular, but in my opinion plays pretty bad i.e. plays tournament style like pushing all-in pre-flop w/ 88 etc. He liked to push all-in pre-flop a lot and would check raise all-in w/ Ace high hands no draw.

Hero has 8 8 [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/diamond.gif[/img] UTG

Hero limps, 1 call, CO raises to 25, Villain calls, blinds fold, Hero calls, limper calls.

Flop: (103) A [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/club.gif[/img] 8[img]/images/graemlins/club.gif[/img]

Hero bets 15, fold, fold, villain thinks for a second and makes it 115. At this point I wasn't sure if he had AK or AQ. AA and QQ he reraises from his position pre-flop almost always. From what I've seen AJ/A10 or less he calls and any draw he calls or maybe min raises.

I didn't reraise in case he has AK. I asked him if he had AQ and flat called.

Turn: (333) J [img]/images/graemlins/heart.gif[/img]
Hero checks, Villain checks. When he checked again I really felt he was on AK.

River: (333) 4 [img]/images/graemlins/diamond.gif[/img]
Hero bets $150, villain calls.

Definitely bet the turn or reraise on the flop? I felt if I reraised on the flop it would end the hand.
