Deep 1/2NL midset multiway pot

[PokerFink]

1/2NL at the Borgata earlier today. 10-Handed.

I am UTG+1 with T [img]/images/graemlins/heart.gif[/img] T [img]/images/graemlins/diamond.gif[/img]. I have $800 and cover everyone.

Preflop: I limp, EP1 (600) raises to 15. Five people call, all have medium stacks (200-400). I call.

Flop (7 players, $105): 9 [img]/images/graemlins/spade.gif[/img] T [img]/images/graemlins/club.gif[/img] J [img]/images/graemlins/spade.gif[/img]

I check, EP1 bets $30, 3 players call and 1 folds, BTN pushes for $170, I push.

BTN is a VERY bad player. Everyone at the table knows this.

Thoughts?
