1/2 NL Live - 89s - my play on the turn?

[BigBluffer]

Background: I've been at the table about half an hour. Won a smallish pot. Came in on a couple of others and folded when the flop totally missed me. I have about $90. Villain (loose/passive so far) has me covered.

UTG+1 I'm dealt 8 [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/heart.gif[/img]. I open for $10 (standard opening raise at this table). CO calls, SB folds, BB calls.

Flop (pot=$31): 2 [img]/images/graemlins/heart.gif[/img] 8 [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/heart.gif[/img] - BB checks, I bet $30, CO calls, BB folds.

Turn (pot=$91): 7 [img]/images/graemlins/club.gif[/img] - if I continue with a half-pot bet ($50), I'll be all in. CO could have any pair or any paint. I don't think he has hearts. I decide to go all in.
