Big stack has pushed allin about 10 straight hands since we got 3 handed. He has shown about half of those hands to us, hands like 66, A4, KJ, 33,Q9, etc.... He has used his stack well at the final table and he is really starting to push us around now. (I have pushed from the button and stole the last 2 times verse the big stack). BB has been ultra tight at this final table. He has managed a few key double ups during the final table with big hands. But I have seen him fold a hand earlier when he was definitly priced in to call and it would not of hurt him if he lost. So, im assuming he just wants to move up to 2nd place.

I'm playing to win as always, but I will add that second place money is 33% better than 3rd place and is meaningful to me in all honesty.

Ok, now to the hand. Button (big stack) open pushes all-in. I am dealt pocket 8's. considering the info i provided do you call or fold?
