This guy was playing a lot of hands. 5 minutes before this hand, him and I were playing heads up, and I think he was still in heads up mode a little bit. After he min-raised me on the flop, I was worried, but I didn't want to put it down there because of the chance he may have had A8, 99, 10-10, JJ, KK.
