Bottom set on drawy board that hits, then rivers underfull

[roggles]

For me, this is a very tricky hand. I'm not going to say too much about my actions, because I just don't really know what to do. As usual I have no reads [img]/images/graemlins/frown.gif[/img] I really need to use PTO, but I don't have windows.

And a theoretical question: If he makes a good bet on the turn, should I just fold?
