200nl trips. Villian wakes up on a brick river

[vancouverspecial]

Never played with villian before, but he's pretty fishy at 51/23/0.77 over 75 hands.

BTN: $127.75
Hero (SB): $208.60

UTG: $445
CO: $289.80

Pre-Flop: Q[img]/images/graemlins/diamond.gif[/img] T[img]/images/graemlins/heart.gif[/img] dealt to Hero (SB)
2 folds, CO calls $2, BTN calls $1, Hero checks

Flop: ($6) 8[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/club.gif[/img] (3 Players)
BTN checks, <font color="red">Hero bets $6</font>, CO calls $6, BTN calls $6

Turn: ($24) Q[img]/images/graemlins/heart.gif[/img] (3 Players)
BTN checks, <font color="red">Hero bets $18</font>, CO calls $18, BTN folds

River: ($60) 2[img]/images/graemlins/spade.gif[/img] (2 Players)
<font color="red">Hero bets $30</font>, <font color="red">CO raises to $90</font>

My first reaction was wtf? second was to fold, third was to call because what the hell hand is he repping?

Any suggestions?

EDIT: BTN is SB in hand (converter messup)
