I went to 2 casinos over the weekend that beat me pretty good when I was a basic strategy ploppy a few years ago. I was able to withdraw some of my lost money from both places. It was a pretty rewarding experience. It seems all the hard work is beginning to payoff. Since switching to AOII I've played 150 hours and am up 185 units. Prior to this I was using Hi/Lo, -52 units 262.5 hours played. I play mostly double and single deck. I realize this is a very small sample size, but I believe I am on the right track.
