Assuming he does the normal lagtag thing and c/r's the flop with a flushdraw or oesd, the only hands you want him to fold is another A. And that's not gonna happen.

So the question remains: if he has a PP, will he bluff the river more often than catch a 2-outer? The answer is yes imo, so I'd check. If he never tries to bluff you like some nitty tags then I would bet.
