A8 turn raise vs 2+2

[Grease]

Part of me loves it, part of me is meh. The thing is, I think we're ahead here a ton, but at the same time, we shut him out and he'll fold when we're ahead. Also, if somehow we're behind, he'll 3-bet or show down always.

I know that you realize that this raise is 100% for value, but against a good playing 2p2er, I'm not sure he'll pay off with a hand that's at least as good as ours. Basically, if he has A2, A3 or A4, we win, but any other time, we're probably behind or tied. I know we have a straight draw as well, but do you think he'll 3-bang an 8 and a FD or just a good FD? If he's that tricky, I would just call down since he'll probably bet the river no matter what, and you'll extract max value without having to fold on the river (I assume if he 3 bangs and the river blanks, you fold?)

However, if he's likely to calldown light because it's a blind steal and you're 2p2, then I really love it.
