My Black jack code

The fundamental principle behind counting cards in blackjack is that a deck of cards with a higher proportion of high cards (tens and aces) to low cards is good for the player, while the reverse is true for the dealer.A deck rich in tens and aces improves the player's odds because blackjacks (which offer a higher payout than other winning hands) become more common, the dealer is more likely to bust a stiff hand, and double-downs are more successful.

Card counters raise their bets when the ratio of high cards to low cards in the deck is skewed in their favor. They also make strategy adjustments based on the ratio of high cards to low cards. These two adjustments to their betting and playing strategy can give players a mathematical advantage over the house.

The popular myth, card counters do not need savantqualities in order to count cards, because they are not tracking and memorizing specific cards. Instead, card counters assign a heuristic point score to each card they see and then track only the total score. (This score is called the "count".)

Basic card counting assigns a positive, negative, or null value to each card (2 through ace). As each card is dealt, the running count is adjusted by each card's assigned value.

There are multiple card counting systems in use, but a plus-minus count such as the Hi-Lo system proposed by Harvey dubHarvey Dubner in 1963.

In the Hi-Lo system the cards 2 through 6 are assigned a value of +1. Tens (and face cards) through aces are assigned a value of -1. Cards 7, 8 and 9 have a value of zero (so they can be ignored).

The Hi-Lo system is an example of a balanced card counting system, in that there are an equal number of +1 and -1 cards in the deck, so a count of all 52 cards would result in an end count of 0.
