1/3 Live AKs easy push?

[overun]

1/3NL live. 7-handed game. UTG limps, an MP raises to 15, shorty with about 120 behind him pushes allin. I have A [img]/images/graemlins/heart.gif[/img] K [img]/images/graemlins/heart.gif[/img]. What to do?

UTG is normally a pretty tight player. He likes to make hero calls once in a while with marginal hands if he thinks he's good. Likes to limp with good hands (big PP, big As) as well as marginal hands (small PP, SCs). I would consider him to be a tight, passive player. His stack is about 300.

MP in this spot is a decent TAG/LAG. Plays tight upfront (though he sometimes raises with SCs and random junk to mix it up) and loose in position. So can reasonably raise with any 2. His stack is about 700.

The allin shorty plays kamikaze poker. He likes to buy in short, then shove it in on 99+, AJ+.

So, this is an ez shove with AK right? Maybe I should minraise? Smooth call?
