Rivered straight on 3F board

[Captain Awesome]

Villain is horrible and loves to bluff. After his first river bet his range is almost ATC but I haven't seen him 3bet bluff a river before.

51/3/1.5 over 150 hands.

Button ($12.20 in chips)
Hero ($706.75 in chips)
BB ($200.00 in chips)
UTG ($210.35 in chips)
CO ($280.55 in chips)

Hero is SB with Q[img]/images/graemlins/club.gif[/img] T[img]/images/graemlins/diamond.gif[/img]

RIVER A[img]/images/graemlins/spade.gif[/img]
Hero checks, CO bets $10, Hero bets $40, CO bets $100, Hero ?

I called because he sucks but didn't feel that good about it. I thought he would show up with a slowplayed set or 2p often enough.
