This was a tricky hand from a 5+1 Party Tournament.

First, a little history:

Should I have isolated pre-flop? I really didn't feel like I had a lot to gain from it. Sattuof, the first to limp, is the only one who I thought might have a hand to call with, and if he was limping a Q's or better, I wasn't expecting a fold. With all the limping, I didn't think anyone had overcards they could call with, such as AK. So really T's and J's were the only hands I was worried about driving out, and just stastically it is less likely that one of those two pairs is out there than that one of the three big ones is.

When Hope called behind me, I put him on a better pair, so even though there were a lot of draws out when I flopped the set, I figured they were more scary to him than they would be to me, and that he would push K's or A's when I checked to him.

So how's my line? Should I have isolated? Would anyone have folded pre-flop?
