Can I maximize my value, or am I just asking for trouble?

[A_PLUS]

UB 10K garunteed (50+5)
End of 1st hour. My image is pretty aggressive, donkish over good.

I have 1600 to start the hand.

Button limps for 60 (2500ish behind, fairly aggressive)
SB completes (1900 behind, nothing jumped out with his play)
I check with A8

Flop (180) 8 8 9 (rainbow)
SB checks. Hero checks. Button bets 180. SB raises to 360.

720 in the pot, about 50% of my stack. If they are awake, a smooth call by me screams 8. I think button can have any 2, but SB most likely has an 8, maybe an OP or A9, maybe JT.

I think an 8 pays me off regardless, A9 maybe, given his stack size. JT only pays me off when he beats me.

Whats your line?
