($33) AKs in BB against button raiser; all-in time?

[30hourdays]

Flat calling seems foul, but an all-in might be premature too. Any insights on how I should be thinking about this situation?

allin is definitely not premature.

push, no other option is even close.

About 1/3 of your remaining stack in the pot, you have no choice.
