I would push all-in.

There is already $2625 in the pot before the flop. BB is betting 1/3 pot, you are calling, and then Button is raising $1150 into a $4325 pot. It is very possible that no sets are out there.

The action in this hand is very strange, both before and on the flop. It's hard to put people on hands here and the pot is huge. I would push all-in.

Here's why I think the action is so strange:

Preflop:
Why is the BB reraising so small here?? There's been a raise and two calls, and then reopens the action by putting in a smallish raise. It seems weird. I think a poorly played AA is more likely than 88.

Then the flop action is very strange. PFR bets 1/3 pot, and you simply cold call. Why? I would put in a raise here, even if it was a smallish one.

Then Button puts in a tiny raise into a huge pot. Why? Can he be sure you didn't call with 56s? This is what makes me think he may not be as strong as raising a bettor and caller might indicate. The initial bet was small, and his raise is tiny.
