Ugly board with a set.... call or raise?

[Kirkrrr]

$20 BI, 180SnG on Stars. Villain, from what I have seen, is mediocre at best and fairly easy to read.

PokerStars No-Limit Hold'em Tourney, Big Blind is t20 (9 handed) FTR converter on zerodivide.cx

MP3 (t1580)
CO (t1880)
Button (t1380)
(Villain)/ (t2800)
BB (t1470)
Hero (t980)
UTG+1 (t1690)
MP1 (t4160)
MP2 (t1320)

Preflop: Hero is UTG with 8[img]/images/graemlins/diamond.gif[/img], 8[img]/images/graemlins/spade.gif[/img].
Hero calls t20, 6 folds, SB(Villain) raises to t40, 1 fold, Hero calls t20.

Flop: (t100) 8[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/club.gif[/img], 6[img]/images/graemlins/spade.gif[/img] (2 players)
Villain bets t40, Hero raises to t120, Villain calls t80.

Turn: (t340) K[img]/images/graemlins/club.gif[/img] (2 players)</font>
Villain checks, Hero checks.

River: (t340) T[img]/images/graemlins/spade.gif[/img] (2 players)
Villain bets t320, Hero...


FWIW, I was fairly certain on the turn that he DIDN'T have the flush, and didn't bet since he was folding all the weaker hands at that point while if I could convince him I didn't have the flush either I could still get one more bet on the river.

Comments, as always, appreciated.
