Make this call with AKs?

[NorthernGuy]

This is the $3 rebuy, but rebuy period is over. Push or fold? I'm leaning towards folding, but is that too weak? I didn't have a good first hour, so I don't have much of a stack... is this the opportunity to go after chips?

<font color="#666666">2 folds</font>, MP1 calls t200, <font color="#666666">1 fold</font>, <font color="#CC3333">MP3 raises to t3000</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">Button raises to t3785</font>, Hero ???

What do you make of MP3's 15x BB raise? I expect to see something like 7's or 8's, and with less than 2000 behind, he's not folding to your push. What do you put Button on? He must have a hand, since he knows MP3 is going to call. Do you feel like gambling?

I'm thinking button has a medium pair, but I figure I'm up against two lower pairs.

This is just past the rebuy period in a $3 rebuy. I call.
