Turn decision, Party 10/20

[icepoker]

Here's a hand from the 10/20 6 max game at Party. UTG is pretty much the average 10/20 player, too loose, not too aggressive though. CO is extremely loose, around 65% vpip, but unusually low pfr for this type of player. On the turn he could have any A, perhaps J/images/graemlins/heart.gif or T/images/graemlins/heart.gif and of course a made flush, a straight, any two pair combo etc.

What's my action, and would you have played it the same up to that point?

All comments appreciated.
