How low would you go...

[Saborion]

... in your calling standards when you are in a situation similiar to this one.

Big live MTT. 3 players left. Blinds at 80k/160k, antes at 15k. Prize structure is like 1M, 500k, 250k.

Button has ~T150k.
SB has ~T5M.
You have about T1M in the BB.

Button folds. SB pushes. He's capable of doing this with any hand that has some value if called, so remove 73o from his range, but include Kx and 78s etc. What's the lowest hand you'd call with, if any?
