Blackjack card counting

Main principle of blackjack card counting

A deck or a shoe with a high percentage of tens (including J, Q and K) and aces favors the player. More tens and aces mean more chances for blackjack and more opportunities to double down. Moreover, it has been *proven* by computer simulations that a high percentage of tens and aces favors the player over the dealer. So if you would know the percentage of tens and aces left in the shoe, you could adjust your wagers accordingly. If the percentage of tens and aces is high you would increase your bet size. If a shoe is rich in low cards you would decrease your bet size. A card counter keeps track of the percentage of tens and aces left in the shoe, and modifies his or her bets accordingly.

Blackjack card counting systems

You might wonder how you can keep track of the percentage of tens and aces left in the shoe. A simple method developed by Harvey Dubner and Julian Braun, known as the High-Low system, is to assign a value of -1 to tens and aces, a value of 0 to 7, 8 and 9, and a value of +1 to all other cards. You would then keep a running count of all the cards that were dealt. If the running count becomes +2 in a single-deck game,a card counter would increase the bet size, and would do so more if there were less cards left in the shoe.

There are many card counting strategies available today, but the basic principle is similar to that of the High-Low system described here. When combining 'Basic Strategy' with card counting it is possible to eliminate the typical house edge of 1% or less, and turn the odds slightly in favor of the player.

Card counting no good for online blackjack

Unfortunately, card counting can only be used in land-based casinos, because in a typical online blackjack game, the cards are reshuffled every round. This means it is simply impossible to keep track of the percentage of tens and aces left in the shoe.

The best Blackjack bets (with the lowest house edge) are offered by Boss Media casinos , because they offer single-deck blackjack. Actually the odds are slightly in favor of the player in Boss Media's single-deck blackjack.
