FT of Stars 160 WSOP DS Hand - AJs versus apparent Button Steal

[r1base14]

The title says it all. I have AhJh in the SB, with 20 BB's left, 7 people remain at the FT of the DS, with only the winner earning the ticket to the big dance. The table in general had been starting to get pretty agressive in stealing blinds. Blind level is 50-100, 3 minutes before the 75-150 level. The only history I have with the button raiser are a couple of BSB battles where he complete his SB and I opped him and CB the flop both time. I won one, and he CRAI the other.

Folds areound to button, who has shown some level of aggression, defintiely not a passive player. He opens for 400, I have AhJh and have 2050 remaining. What's my play?

My thought process is as follows: He could be raising any Ace, any two broadway, any mid-high SC's, and any PP. My stack size is not optimal for a stop and go, as I will have substantially more than a PSB if I just call. So it appears to be all in or fold time. I pushed. Thoughts?
