On the other hand, he did call a $20 RR PF, and you mention he's TAG. If he's calling that size RR without an Ax or a big PP, that doesn't mesh with TAG.

I'm going to have to use your info to check/fold this flop if he bets; I can give this guy credit for an ace if he throw's out a pot-sized bet at my check. Anything less than that and I'm popping a big RR at him.
And if he calls?
