Ken,
You know how to spot the APs?
Other than the nerdy glasses. They often don't bet unless they know that they have the edge. They often have to consciously remind themselves to places bets in order to keep from standing out when setting up a play.
I told you, a couple years back, I did spot you at Poto. Agreed, I might be wrong but I would bet it was you. By yourself, glasses, a bit tall, arms folded, watching and watching. (no, I am not Asian).
