House edge evaluation
Blackjack game can be defeated, but not that easy gains can be obtained from the casinos, because casinos will set up some rules to help them to obtain a comparative advantage in every game. Casinos can not beat the players in a short term because of good luck, while the casinos are able to rely on the advantage to ensure the long-term profit making. We call the advantages as house edge, which is the main income source for casino. For example, the advantage of the 21 game for dealer is about 5%, meaning when a player bet every 1000 dollars there will be 995 dollars then returned to the player, while the remaining 5 dollars will be taken by the casino. If you play with bad gambling rules, you may be unable to compensate for the harvest time to pay for risk. In addition, the different gambling rules will affect basic strategy and the way of betting. So before you sit by the playing table, you should evaluate the game from various angles, as the game rules have a great impact on the calculation of house edge. Here are some simple data which helps us to calculate the house edge under different rules.
First, we assume that the basic rules of the casino is: 8 cards, dealer hit soft 17 (H17), player can double at any two cards (DA2 or DoA), double after splitting(DAS), no resplitting A(No RSA), resplitting to 3 hands, insurance allowed. The casino has the house edge of -0.65% under this situation.
Single deck +0.48%
Two decks +0.22%
Four decks +0.06%
Six decks +0.02%
Dealer Hits on Soft 17 +0.2%
Player may double on 9-11 only -0.09%
Player may double on 10, 11 only -0.18%
Player cannot double after splitting -0.14%
Player may resplit aces +0.07%
No respliting -0.04%
Early surrender allowed +0.70%
Late surrender allowed +0.08%
No insurance -0.40%
The above parameters are based on the rules we originally assumed, and players can re-calculate the house edge under the different situation. For one, if you're playing blackjack with four decks of card under the same conditions, we can do the calculation as follows:
Basic advantage of the players: -0.65%
Four decks of value: +0.06%
The advantages that players gained: -0.59%.
According to the above method, players can accurately evaluate the corresponding advantages of the casino they plan to go, so as to develop a series of strategies to beat the casinos.
