Blackjack Card Counting for Dummies
What is blackjack card counting?
Getting as much math out of the way as possible, card counting is a blackjack strategy by which one keeps track of the ratio of good cards to bad cards in a deck. By good is meant cards that are better for the player, and bad means the opposite. The more good players left in the deck (i.e. not drawn), the better for the card counter. When the card counter realizes that there are more good card remaining in the deck than bad ones, they can raise their bets proportionally to win more.
Generally, low value cards 2, 3, 4, 5 and 6 are treated as bad cards. 7, 8 and 9 are neutral. Face cards, 10 and aces are good cards. This is because with high cards on the deck, there are bigger chances of a blackjack for the player as well as the dealer (who has no choice) going bust.
Where did blackjack card counting begin?
The mathematician and physicist Edward Thorp is considered to be the father of modern card counting and other gambling tactics based on arithmetic. Although other gamblers had counted cards before, it was his book "Beat the Dealer" (1962) that gave the casinos a run for their money. In fact, casinos felt so threatened by Thorp's system that they were forced to abandon single, hand-held decks and started using multiple or shoe-decks for blackjack. This makes the work a little harder for card counters, but not impossible.
Is card counting illegal?
