Real early in a 10+1

[chim17]

I recently had to cash out most of my bankroll so I left 200 bucks left in and am starting over at 10+1's. This hand actually brought about some confusion.. and I wasn't sure what the best move preflop was. This is in a Party so blinds are 10/15.

Hero looks down and sees A [img]/images/graemlins/heart.gif[/img] K [img]/images/graemlins/club.gif[/img] and is in the BB.

Stacks sizes not relevant, really.. third hand and not much has happened.

So I get 4 limpers, UTG, MP, CO, and Button. SB calls and I , in the BB raise to 80. I get a call from UTG, MP/CO folds, and Button now raises to 200. I think for awhile thinking he would have had to raise AA/KK/QQ here after these limpers and I push.

Thoughts?
