Bad villains bad villains whatcha gonna do?

Whatcha gonna do when they come for you?

5-10 NL at Pokerroom, 7 handed, I have $1557 in the SB and villain has ~1800 in the BB. Read on villian is he's loose (something like 45-17 PT stats) and may overvalue hands slightly. Postflop play he's a bit of a LAG but not ridiculous. I don't know if he's perceptive enough to see my river bet as a blocking bet.

Hero is SB with J [img]/images/graemlins/spade.gif[/img]9 [img]/images/graemlins/diamond.gif[/img]

UTG folds, UTG+1 folds, MP1 folds, CO folds, Button folds, Hero completes, Villain checks.

Flop T [img]/images/graemlins/heart.gif[/img]K [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/diamond.gif[/img] (Pot: $19)
Hero bets $15, Villain calls $15.

Turn Q [img]/images/graemlins/spade.gif[/img] (Pot: $48)
Hero bets $45, Villain raises to $100, Hero reraises to $295, Villain calls $195.

River 4 [img]/images/graemlins/club.gif[/img] (Pot: $637)
Hero bets $300, Villain raises to $937 (All-in for Hero), Hero...?

Preflop: ehhh I fold sometimes, but I'm an action junkie, why not. Doesn't matter much either way I'm pretty sure.
Flop: battle of the blinds, let's try and tear it down.
Turn: or that works. Gotta reraise.
River: derrr
