Blind Defense w 99

Context: Villain has only been around for a couple of orbits. So far, he's been playing a lot of hands and been pretty aggressive. My impression is that he would open-raise from the sb with anything remotely close. I don't know how much he's paying attention, but I'm having a very good session and may look like a bit of a bully. Probably running about 32/24 at the table because I'm getting a bunch of good cards. The thought crossed my mind that he may be trying to take me on.

Prima 1/2 5 handed

Folded to sb who raises, Hero 3bets, villain caps, Hero calls

Flop (8sb, 2players): 6 [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/spade.gif[/img] T [img]/images/graemlins/spade.gif[/img]
villain bets, Hero raises, villain calls

Turn (6bb, 2players): A [img]/images/graemlins/club.gif[/img]
villain bets, Hero ...?

Time to stop? Continue with calldown or raise? If I keep going, what are my plans for the river?
