JJ and 10/10 hands on the bubble facing all-ins, PP $11

This first one really isn't the bubble, but it's close. UTG didn't show to be a maniac or extremely aggressive. At least up until now.

Hero?

Against a shorty I'd have insta-called, but against someone with nearly the same amount of chips as I had I didn't know what to do. Plus the fact that it was UTG. I'm guessing I'm ahead here. But probably in a coinflip.

Here's 10/10 later on.
