after you read all of those books that basically teach the same thing in different ways, read..."Fast and Slow Thinking" by Kahneman. This book helped me revolutionalize the game. I cant count how much feedback I am getting in emails for visions. Introducing psychology into the game and refining things like my controllable variables (ie. table capacities) is where its at. Although I will have to say I did start with "Beat the Dealer" like everyone else.
