Double Deck Blackjack
When the advantage shifts in favor of the dealer, the counter will make a smaller bet or no bet at all by not playing. Counters can gain a positive advantage over the casino by varying bets in this manner. I’m very interested in turning the small house edge in blackjack into an essentially even game with the house. I know this will not change my results all that much, but I think it is a psychological barrier that many players wish to pass.
Now let’s see what happens to a player who learns one of the simple entry-level card counting systems I’m about to explain. Much of the challenge of card counting is avoiding suspicion that you are anything but a normal non-counting player. The most obvious indication that somebody is counting is that they make a substantial increase in bet size after a lot of small cards leave the table. Although the greater the factor by which you can increase your bet the greater your odds of winning, more than doubling your last bet is a fast way to arouse “heat”from the dealer and pit boss. Usually when casinos employees realize you are counting, they will either shuffle the cards whenever you increase your bet, essentially removing any advantage, or ask you to leave. To compensate for the reduced edge percentage when Aces are removed from the deck, the Aces are assigned a value of -1 in the running count. Snyder believed that this was just as effective as the elimination of Aces from the running count and counting them separately, as it is with other card counting methods. http://yerbabuenanursery.com/docs/pages/introduction_to_blackjack.html
This has the same effect of eliminating penetration, just as with a continuous shuffling machine, making card counting impossible. In most counting systems, the player will use this true count to decide how much to bet on a given hand, and whether or not to take insurance if the dealer is showing an ace. Card counters can take advantage of knowing how good the remaining deck is in several ways. As we said earlier, card counters will sometimes take insurance based on the remaining cards in the shoe, and on rare occasions, they might even deviate from basic strategy based on their counting. However, the biggest way that card counters pick up an advantage is by simply betting more money when the player has the advantage, and betting less when the odds swing too far in favor of the dealer. Card counting is a technique that lets blackjack players know when the advantage shifts in their favor. When this occurs, card counters will increase their bets.
I play basic strategy religiously and am comfortable with counting cards using the Hi-Lo sytem, but mainly do it just for a challenge at the moment as I don’t use much of a bet spread. On your blackjack page, in the House Edge section, you indicate that the player has the edge in single-deck blackjack. Numerous Vegas Casinos offer single-deck blackjack, but I doubt they are dealing a losing game. Is your page incorrect or are the casinos just gambling on their clients not being able to play basic blackjack.
This somewhat makes the Zen Count system a bit less complex than other systems as it gives players one less thing to be constantly taking into account while playing blackjack. If the deck is dominated by small cards, the card counter is at a disadvantage, and he needs to bet small. In short, card counting has been designed to help players see if they have the edge in a certain round when playing blackjack. It’s also worth noting that there are a large number of blackjack games in which you won’t be able to effectively count cards at all. For instance, many casinos now use continuous shuffling machines, which essentially remove all deck penetration. Some online casinos use a shoe made up of infinite decks, meaning that your odds of getting any given card are always exactly the same, no matter which cards you’ve seen. Other online casinos deal out of a regular shoe, but shuffle the cards after each hand.
