PP 5/10: KK capped preflop. what to do against a sudden turn raise.

i've only been at the table for 2 orbits, but it's one of the ones where everyone folds to an early raise preflop(18% table vpip). i haven't seen too much out of the button. he has low stats but over 2 orbits that doens't mean very much.
