Those cards are what is known as basic strategy. It represents the best mathematical action based on every combination of your starting hand and the dealers up card.





For example, if you hold 13 and the dealer is showing 9, you should always hit. (Assuming 4+ decks and dealer hitting soft 17).





So those cheat cards you talk about are where playing Blackjack begins. Counting cards, or any other kind of strategy cannot really happen until you get this bit right. Because anything else you might try to do to get an edge would be negated if you fail to follow the basic math of the game.





But if you are a beginner, this would be a good starting point.
