5/10NL at 300BB. Really weird [censored] turn...

[Kirkrrr]

Me and Villain have been playing for several hours now. He's very loose pre-flop and on the flop, but overall very passive and a habitual underbettor with everything . A 3xBB raise usually means a drawing hand of some sort. I'm playing a fairly TAG game (the pre-flop re-raise was completely out of the ordinary), but overall running somewhat cold.
