3/6NL: awkward set play against short & big stack

[HoldEmKillah]

I just sat down about an orbit or so ago. BB is tag..21/8/2. How do I extract here without having my hand scream set? Is there no way around it? I just have to jam-reraise here?

What's the best line? Both of their lines look like draws to me but I'm assuming only one of them is. The problem is that if the short stack is on the draw and I jam it then I'll be scaring away the BB's top pair hand. On the other hand, if I play it soft and the BB has the draw then I'll be giving him infinite odds. I could just flat call and see if he reraises to isolate whereby I could come way over the top but that seems way too risky. What to do?
