Bodog 7.5k final table AA in BB.... play along.. do you call

Down to 5 people I am short, but not bad because I am stealing to stay where I am and not falling behind.

Avg stack 155k
Hero in the BB with 121k
SB chip leader at 300k

Hero dealt 2 black Aces in the BB

Blinds are 4k/8k with 800 ante

SB mini raises to 16k and I value raise to 16k showing I am not affraid of his stack with this hand.

Flop is 2d Qs 8d

SB checks I throw in 14k (value betting, probably a little small)

SB calls

turn is 10d

SB checks I bet 45k

SB reraises me all in

I am sitting at 37k left with a decision to make.

There is a str8 and flush draw out there or he could be big stack bullying.

What do you do?
