What's your image? You're in the blinds I assume? If I were to play 88 here (I don't think you're necessarily of Joe's UTG range), I'd 3-bet preflop from anywhere but the big blind.

And value bet the river as played. I'd be pretty surprised if Joe raises you here (he doesn't have a 7, and he's usually fairly aggressive on the earlier streets), but if he does, I think whether to call or fold depends a lot on what he thinks of you.
