A couple of questions:
1) What about preflop? Anyone flat call here? I wanted to reraise to isolate against the shorties, esp. with all that money already in there... should I raise bigger?

2) I'm really lost postflop with a basically dry sidepot and a huge mainpot. Didn't see any need to bet flop with the nut draw. Just don't know how much to bet/raise my big hands here...

thanks
