This online trainer teaches you how to count cards for use in all kinds of games, especially poker and blackjack.
From Wikipedia, the free encyclopedia
Card counting is a card game strategy used to determine when a player has a probability advantage. The term is used almost exclusively to refer to the tracking of the ratio of high cards to low cards in blackjack, although it is sometimes used to refer to obtaining a count of the distribution or remaining high cards in trick-taking games such as contract bridge or spades. This article deals only with card counting as it applies to blackjack.
Card counting in blackjack
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.
Contrary to the popular myth, card counters do not need savant qualities 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".)
