AK on the bubble

[Roland]

Hi guys,

First post here. I’m just recently started playing SNGs, so I probably suck. Actually, forget about the probably.
Anyway, I got myself in trouble in a 55 just now. Here’s the hand:


Party Poker No-Limit Hold'em Tourney, Big Blind is t500 (4 handed) converter

SB (t590)
BB (t4060)
UTG (t1965)
Hero (t3385)

Preflop: Hero is Button with K[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises to t1500</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">BB raises to t4060 (All-In)</font>, Hero ???


FWIW, the BB had been pushing a lot but I didn’t have any real read on him.
I’m totally lost here. Should I fold this PF? Limp? Push?
I’m pretty sure I have to fold this after he pushes, right?
