Supernova tourney. Call all in push from button w/ A8h?

[ryanghall]

Villain is 13/12 or something over 100+ hands.
Let's assume he's decent. I have been 8 tabling so I don't really know for sure but I don't recall him doing anything stupid. His att to steal % is 25% over a small sample. Notice BB only has 6x BB. Make the big call?

Edited to add: We're about 50 people from the money bubble.
