Hand 1: Villain had a high ATS, although it went down as the session went on. His stats looked laggy at the time, but his PFR went down later so he might be a TAG reg on a card rush. I've 3b him twice before (one time lightly and one time with KK) and I was worried he would stop giving me credit. I decided to call and make a move post-flop.
