AKo on bubble, should I just call?

[Vee Quiva]

I am trying to look at hands from a different point of view here. All the players are reasonably solid. I haven't seen any huge mistakes from them so far.

My first instinct is to move all in and see 5 cards with Ace-King.

After further thought, could it have been better to just call and see a flop? If it hits me, I bet the rest of my chips. If he checks, I can take the chance and bluff at it or save my chips for another hand, when I'm first in the pot.

Or am I out of my mind?
