Blackjack: Basic Counting
Alright. Many card counters have developed different systems for counting cards. This, however, is the simplest to do, and the method depicted in 21. Each card has a value. 2-6 are +1, 7-9 are 0, and 10, face cards, and aces are -1. The concept to remember here is that you’re actually counting the number of “extra” large cards in the deck.
As cards are dealt, the counter keeps a “running count” using the values above. It is actually easier to wait until the hand is fully dealt out, and play begins to count the cards. Each player now has a pair of cards which range in value from +2 to -2. The player then counts individual cards as players “hit,” as well as counting the dealer’s hand when it is exposed.
The “true count” is where experience in blackjack comes in handy. The true count is the running count divided by the estimated number of decks still left in the shoe.
The common misconception is that strategy significantly changes when counting cards. This is not actually true. First, players who play with the level of strategy of most card counters would be very easy to notice changing their strategy according to the count. For instance, if there is a very low count, meaning a lot of small cards remain in the shoe, it may make sense to hit against a bust card.
Where counting comes in is money management. When the true count is 2 or more, there are a lot of face cards left in the shoe. Remember that basic strategy is based largely on the assumption that any card you cannot see is a 10. With a high count, this is even more true. So a card counter increases their bet dramatically when the true count is 2 or more, and plays the hand with perfect strategy.
On the other hand, when the count is extremely low (-2 or lower), there are few face cards and a lot of small cards in the shoe. Assumptions like the dealer busting if they show a 6 go out the window, and the game becomes less predictable. At this point, a counter is likely to decrease their bet, or sit out entirely.
