5/10: Have a flush, raise river bet?

[PokerFink]

Venetian 5/10nl, 9-Handed.

Villian is a young TAGish pro. I've never played with him before, and it's tough to get a real read because there are three really bad players in the game and everyone else is just waiting for a good hand.

Effective stacks are 1500ish.

Hero has T [img]/images/graemlins/club.gif[/img] 3 [img]/images/graemlins/club.gif[/img] in the BB. Villian is in the SB.

Preflop
Two limpers, Villian completes, Hero checks.

Flop (40): K [img]/images/graemlins/club.gif[/img] 4 [img]/images/graemlins/diamond.gif[/img] J [img]/images/graemlins/club.gif[/img]
Checks around.

Turn (40): 5 [img]/images/graemlins/club.gif[/img]
Villian bets 30, Hero raises to 100, limpers fold, Villian calls.

River (240): 8 [img]/images/graemlins/heart.gif[/img]
Villian bets 160, Hero...

Call or raise?
