JOSH folds
JEREMY pushes all-in
ME (A6o) ?

I am the newbie at the table. Both JEFF and JEREMY are very good, semi-pro players. I am very afraid to tangle with either. JOSH is a good player, but capable of making mistakes. He got very lucky twice earlier at the final table to accumulate his big chip lead.

what should I do and why?
