AK in the bb, wierd pf action

[NLHE lahooozaher]

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?

Preflop: Hero is BB with A, K.
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.....
