Under the Hi-Lo method of card counting, each numbered card has a value. Cards two through six are worth one point. Cards seven through nine are worth zero points. The ten card, face cards, and the aces are worth negative one point each.  The idea is that you’ll keep a total value of all the cards on display, and as more face cards are left in the deck you’ll make more blackjacks while the dealer busts more. The Hi-Lo method is a common counting system, but other systems exist that give different point values to certain cards such as aces and fives. Use a single deck of cards. Turn over the cards one by one, adding up the values as you go. If you draw a two, a five, and an ace, you’ll have a value of one. When you reach the end of the deck, your running total should equal zero. Repeat practice until you’re able to keep your total quickly and quietly. Casinos are wise to card counters, so they play blackjack with multiple decks at the same time. The true count takes the running count and divides it by the number of decks in play. This count gives you more of an idea of how much of an advantage you have in betting.  A running count of three is fine in a one-deck game, but this number means less when there are multiple decks since there are more cards to factor that reduce your chances of winning. For example, a seven running count divided by two decks leaves you with a true count of about three. But if there are six decks in play, the true count is only about one. Start off by using a few decks. Flip over the cards one by one and grow accustomed to dividing with fractions. At first you can simply round the division into a general true count, but as you go you’ll become more able to perform more accurate divisions in your head with less effort. An online card counting simulator can help you practice. Some simulators can correct your counting mistakes and track your winnings. Once you feel comfortable keeping a true count, try mimicking the feel of a casino. First, start small. Add a little music or radio...
