2. Counting cards in blackjack (as seen in movies such as Rainman, The Hangover and 21) consists in keeping track of a count: the higher the count, the more likely it is for the next card drawn to be a high card. One version of this uses the following setup: . the cards 2, 3, 4, 5, 6 are given the value +1, e the cards 7, 8, 9 are given the value 0, e the cards 10, J, Q,...
