Bully on the Button

[TheOak]

This hand is discussed on a dutch forum and the opinions of users were wide spread. So I am curious about the reactions of the users of 2+2.

Situation:
* MTT at Party $4k gtd
* Started with 1.200 players and 375 left
* Villain just came to the table and only played 5 hands
* Villain is overall chipleader with $ 42.000
* Villain has a sawflop% of 100%
* Villain pushed 2 hand pre-flop and 2 hands after the flop. None of these were called by his opponent (so he is the table bully)
* Villain is on the BB
* I have a stack of 7.000
* Blinds are at 200/400


I am on the button and I get A[img]/images/graemlins/diamond.gif[/img] - J[img]/images/graemlins/club.gif[/img]. Everyone folds towards me and because I am on the button I make a normal raise of 1.400. The SB folds.

Villain on the BB pushes all-in again.

What should I do in this situation?
