line check, flopped str8, 1/2NL

[TheChad]

There really is no cap on the buyin in this game. Some nights it plays like a 1/2nl, some nights 5/10nl. Yeah, it's a real live, juicy game.
BB is a loose passive donkey. MP plays really any two cards and is much more agr post flop.
BB has about $80 and MP around $260. I'm sitting in LP with about $200.

1/2NL, 9 handed
PF: Hero is dealt [9 [img]/images/graemlins/spade.gif[/img] 7 [img]/images/graemlins/heart.gif[/img]] UGT folds, UTG+1 calls, all MP calls, I call, 1 fold, CO calls, button folds, SB calls, BB raises to $12, 1 fold, MP calls, 2 folds, I call, 3 folds.

Flop 3 handed, $48 pot: [J [img]/images/graemlins/heart.gif[/img] T [img]/images/graemlins/club.gif[/img] 8 [img]/images/graemlins/heart.gif[/img]] BB bets $10, MP calls, I bump to $50, BB folds, and MP calls slowly.

Turn $168 pot: [4[img]/images/graemlins/diamond.gif[/img]] MP leads for $50. I'm thinking either the heart draw and he's trying to confuse me or he thinks two pair/TPTK is good. He's been showing down some weird hands (flopping two with things like J4o, K7, T6o). The only thing strong I can see from him is a set and I just feel golden. So I shove for about $85ish more and he snap calls.

Thoughts? I felt like I didn't want all of the action I was getting.
