Some of the casino players try to decrease casino house edge by using card counting systems.
The most popular counting system is Hi/Low developed by Harvy Dubner. Low cards 2, 3, 4, 5, 6 are assigned a value of +1, middle cards 7, 8, 9 – a value of 0, high cards 10, J, Q, K, A – a value of -1. This system is considered balanced as the sum of all cards in one deck equals zero. As the cards are played out the player counts the point score and whether it's high or low the player should raise bets or pass respectively. A
lthough the system doesn't require unusual mental abilities (simple mathematical operations of addition and subtraction are used) the players can face some difficulties. First of all, even one card missed can lead to the miscalculation and the loss in the game.
Secondly, casino administration (both real and internet) has found the technology to detect and countermeasure card counters. In real casino it is players blacklist, pit bosses, computer technologies for counters detecting. In online casino it's increasing the number of the playing decks. Of course, you may find a single deck blackjack, but most common blackjack games are played with 6 or 8 decks. To count cards in this case is harder, as you have to divide the score point by the number of the decks. The bet limits in online blackjack are lower than in offline blackjack, so you can't win a lot from just one game. Another "con" is that card counting system gives a probable advantage, not the guaranteed winning (especially on the short distances).
