Bottom two against a tough player

[Rococo]

2-5 NLH 5 handed.

This is a relatively common situation, but tricky nonetheless.

Villain has approximately $630. I have him covered. Villain is an occasional poster on this site, and a consistent winner. He is a little on the tight side, but uses position very effectively. I have a lot of respect for his play. He probably views me as aggressive but not crazy.

Preflop

Folded to Villain, who limps on the button. I check in the BB with 3 [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/club.gif[/img]

Flop

J[img]/images/graemlins/heart.gif[/img] 3[img]/images/graemlins/club.gif[/img] 7[img]/images/graemlins/diamond.gif[/img]. Villain bets $15. I call. My guess is that Villain bets this flop every time that he gets a piece, and about half the time that he misses.

Turn

Q [img]/images/graemlins/spade.gif[/img] I bet the pot.

Does anyone prefer a check-raise on the flop? Does anyone go for a check-raise on the turn? Would your answers differ if the flop wasn't rainbow?
