AK in the bb, wierd pf action

villain is 30/16. I have been raising alot and I raised a few limpers the last time I was in the BB. I also haven't showed a hand in a long time, so who knows what they think, I wasn't playing maniacal though. From his action it seems my hand is likely a coinflip, his most likely hands, IMO, are 22-88. So should I push, call, or fold?

1 fold, AceT(z)en calls $0.25, Button calls $0.25, SB completes, Hero raises to $1.25, Button raises to $4, SB folds, Hero?

I've seen this retarded kind of play plenty with AA and KK but given villain is 30/16 I assume he would raise here if he had them. Tough spot. Being nittish I'd fold oop with AK here but I'm quite interested to see what others have to say.....

shove it in

easiest push ever.

we have the nuts, shove it in!
