Yes, it's that easy...
Like a professional athletic trains over and over to reach perfection. You will have to do the same if you want to be a professional gambler.
While I have tracked and documented the outcome of the next hand, ties, pair, and repeaters, it's my recommendation that you start with a Pro CheatSheets which is the best value. You can start with one of 4 concepts and increase your knowledge base as you understand how to use a cheatsheet and become a professional gambler
Tracking the next hand in a shoe is probably the easiest. Your pre-printed cheatsheet will tell you the frequency for Bet Selection of each hand 1 to 48 hands starting with the first hand. Why 48 you ask, well I look for consistency and continuity so there has to be a controlled number to work with and 48 hands are what I selected based on the fact the casino card has 48 hands.
This is a way to hedge your bets. It is important to have a strategy, if you don't, then check out strategies on this website. Like I said before, 6 out of 10 times a cheatsheet is right on when it comes to Bet Selection. Therefore, 4 out of 10 times it's not, or it breaks even. But hey, a 14% edge over the house is better than 50/50.
