is this a calling station you're up against? I don't think with that board you ever slow down. This is how I would play it. They'll call you down with crap all the time.

I don't bet the river. I figure he's about equally to have an A or T until the 2nd T shows up, then it doesnt matter if he has either. You ain't winning that hand more than half the time.

Word, with a villain this passive I'd be inclined to slow down on the river. Probably not going to win this over 50% of the time.
