Party $30k FT hand

[Ian J]

Party $30k Guaranteed. Final table. Blinds 1000/2000.

I am UTG w/ 45k and raise to 5500 w/ AKo. Absolute donkey w/ 150k reraises the minimum. This guy is like horrific bad, limping 73s UTG, betting literally every flop for the minimum, etc. etc. Just as I'm ready to push my little slider to all in and move it in there, the SB jams for about the same amount as me.

I'm not sure if the SB knows the extent of the big stack's donkishness, but he has to realize that big stack is not v. good.

Soooooooooooo, should I be calling off all my chips here?
