Underfull faces a huge river bet

[edge]

Party 5/10 5-handed. Villain is "battling" (his words) with the player to my right. I'm staying out of their way and playing very straightforwardly. I open with 2[img]/images/graemlins/heart.gif[/img]2[img]/images/graemlins/club.gif[/img] on the button with 1300 behind. Villain calls in BB with me covered. He's kind of dumb LAG. Maybe he's on tilt; I don't know. I haven't really been paying attention to this table.

Enough story. Flop T[img]/images/graemlins/club.gif[/img]4[img]/images/graemlins/heart.gif[/img]2[img]/images/graemlins/spade.gif[/img] with 85 in the pot.

Villain checks, I bet 65, he calls.

Turn 6[img]/images/graemlins/club.gif[/img] with 215 in the pot.

Villain checks, I bet 160, he calls.

River 4[img]/images/graemlins/spade.gif[/img] with 535 in the pot.

Villain pushes. I have about 1000 left.
