Is it ok to go broke in this Setup?

[Sonnix]

I have no Hand History for this hand, sorry.

Villain is a imo the best Regular on my Limit. My Stack is 100BB, he has about 350BB. There was a potsized raise from villain preflop, i called.

My Hand: KKxx

Flop: AAK

He bets pot, i pot it again and he raises me All In. Is it ok to call here? Im about 90% that he has at least one Ace.

Outcome in white:

he has 2 Aces in his hand [img]/images/graemlins/blush.gif[/img]</font>
