A blackjack game in progress

Card counting is a strategy that enables the skilled Blackjack player to make a long-term profit. Blackjack became the most popular casino game in the 1960s and 1970s after the publication of Beat the Dealer by Edward Thorp, which introduced manageable card counting systems.

The larger the proportion of aces, face cards, and tens remaining in the deck, the more favorable the odds are for the player. Players take advantage of this by increasing their bet sizes and altering playing strategy. Some casinos consider this cheating and will ban card counters from playing.

That the player can win with card counting results from a simple rule: Although the player can stand or hit on any total, the dealer must take a hit until reaching 17. The greater the richness of the deck in ten-value cards than a neutral deck, then, the greater the chance of the dealer busting, leading the player to place larger bets and make less conservative strategy choices in such cases. The converse is true is ten-value card poor decks.

Although blackjack dilettantes create an encyclopedia of analysis and manufacture unwieldly jargon to provide a scientific aura around card counting, that rule is the dominant mathematical factor and the basis for all card counting systems.

Basics

The most common variations of card counting are based on theoretical and statistical evidence that high cards (especially aces and 10s) benefit the player more than the dealer, while the low cards, (especially 4s, 5s, and 6s) help the dealer while hurting the player. A high concentration of aces and 10s in the deck increases the player's chances of hitting a natural Blackjack, which pays out 3:2 (unless the dealer also has blackjack). Also, when the shoe has a high concentration of 10s, players have a better chance of winning when doubling.[1] Low cards benefit the dealer, since according to blackjack rules the dealer must hit stiff hands (12-16 total) while the player has the option to hit or stand. Thus a dealer holding (12-16) will bust every time if the next card drawn is a 10, making this card essential to track when card counting.[2]

Contrary to the popular myth, card counters do not need unusual mental abilities in order to count cards, because they are not tracking and memorizing specific cards. Instead, card counters assign a point score to each card they see that estimates the value of that card, and then they track the sum of these values – a process called keeping a "running count."[3] The myth that counters keep track of every card was portrayed in the movie Rain Man, in which the savant character Raymond Babbitt counts through six decks with ease and a casino employee erroneously comments that it is impossible to count six decks.

Systems

Since the 1960’s numerous computer-based systems have been developed. The following table summarizes the values assigned to the cards in the most popular and most powerful systems. References are provided to the published books of computer analyst experts, most holding advanced degrees including the Ph.D or M.A. in mathematics or probability and statistics, who developed the systems. Only authors of reputable, published books, in which the systems have been published, as opposed to any of the hundreds of self-published commercial websites, are referenced. The card value assignments of a comprehensive list of one hundred possible systems, up to level four systems, are provided by Blackjack Hall of Fame member Arnold Snyder.[4]

In the Media

Never Split Tens!, a novel based on the life of pioneering card counting theorist Edward O. Thorp, by Les Golden published in 2017 by Springer, includes numerous examples of card counting in simulated casino play including changing bet sizes, the Kelly criterion, group card counting, and entering the play when the deck is favorable to the player.
