Blackjack is a system for determining the weight of cards for winning

This system serves to determine the weight of the cards for winning. What does it mean. The system divides the deck into upper, lower and neutral cards, respectively, a certain index is assigned to the map in each group.

Map The index of the map in the system of determining the weight of the map
King -1
Lady -1
Knave -1
10 -1
9 -1
Ace 0
2 0
8 0
3 +1
4 +1
5 +1
6th +1
7th +1

As soon as the first card appears, the player starts his account from scratch. For example, if a player saw that one of the top cards came out (9, 10, jack, lady, king), then he subtracts the unit from the total. If one of the lower cards (3, 4, 5, 6, 7) comes out, then the player increases the total by one. If a neutral card (2, 8, ace) appears, the total remains unchanged. Since the number of top cards in the deck is equal to the number of lower cards, the player's score starts with zero and ends with zero. Let's say the following cards appeared in this order: 3, 7, ace, 5, 6, 10, king. Starting from zero, the player sequentially receives: 3 (+1), 7 (+2), ace (neutral, therefore the result is considered equal to +2), 5 (+3), 6 (+4), 10 (+3 ), The king (+2). If the player's score is positive (call it the current account), then the advantage is on the player's side. If the account is negative, then the advantage is on the side of the banker. If the current score is zero, then the odds are equal. So, the higher the positive result at the end of each game, the more the player has a chance to win and the more he can bet on playing with the same deck. When the player's current account is negative or zero, the player must make a minimum bet, while using the strategy of the game .
In order to master this system, do the following.
Take a deck of cards and, opening one map, name its index from the table, which is higher, it is +1, -1 or 0. Continue to do this until you bring everything up to automatism, that is, the index of any card will not be recognized instantly.
Go through the entire deck, opening one card at a time after the other and guiding their score. The account starts from zero and must end with zero. Counting should be done quickly.
Practice in the account, opening two cards at the same time. Summarize the result of each pair. For example, if you opened the top five and ten, the result will be zero. Exercise until the result is determined instantly for any two cards.
Ask any friend to play with you. Look at your results using the game strategy and keeping the score and without it all.
