NL50 Flopped nuts now vulnerable - Shove river anyway?

[Dr_Doctr]

Hand converter I use isn't working. Villian seems like a bit of a calling station postflop but the read isn't very strong. He has never limped UTG before and the rest of the table are passive so I limp along. Hero is Lag - How is my line here?

Effective Stacks 60 / 5 players

Hero is CO with T [img]/images/graemlins/heart.gif[/img], 9 [img]/images/graemlins/club.gif[/img]

UTG calls, Hero calls, Button calls, SB folds, BB checks

Flop (2)

8 [img]/images/graemlins/spade.gif[/img], Q [img]/images/graemlins/club.gif[/img], J [img]/images/graemlins/club.gif[/img]

UTG bets 3, Hero raises to 11 (probably should have raised more - agree?), 2 folds, UTG calls

Turn (23)

River (62)
