Last Update: Mar. 18, 2013
I overhear a lot of bad gambling advice in the casinos. Perhaps the most frequent is this one, "The object of blackjack is to get as close to 21 as possible, without going over." No! The object of blackjack is to beat the dealer. To beat the dealer the player must first not bust (go over 21) and second either outscore the dealer or have the dealer bust. Here are the full rules of the game.
Wizard's Simple Strategy
I've been preaching for years that to play blackjack properly requires memorizing the basic strategy. However, after pitching the basic strategy for 20 years, I've learned that few people have the will to memorize it. In my book, Gambling 102 , I presented a "Simple Strategy," which is seven simple rules to playing blackjack. The cost due to incorrect plays with the Simple Strategy is 0.53%, under liberal Vegas Strip rules.
Ever since my book was published it has bothered me that the cost in errors to my Simple Strategy was too high. So in September 2009 I developed the following "Wizard's Strategy." The cost due to imperfect plays is 0.14% only, relative to liberal Vegas Strip rules. That is the cost of one hand for about every 12 hours of play. Compared to the 250 cells in the Basic Strategy, the Wizard's Strategy has only 21, as follows.
Let me be perfectly clear that this strategy is not right 100% of the time. I continue to get Emails saying that when this strategy was used with my practice game, the player was corrected for following it. For example, my simple strategy says to stand on 12 against a 2, when it is mathematically better to hit. If you want to learn a strategy that is correct all the time you should use the appropriate basic strategy for the set of rules you are playing.
Here are some comments of clarification.
For the appropriate basic strategy for just about any set of rules, please visit my basic strategy calculator. I still have my traditional charts too:

|Player may resplit aces||0.08%|
|Split to only 3 hands||-0.01%|
|Player may double on 9-11 only||-0.09%|
|Split to only 2 hands||-0.10%|
|European no hole card||-0.11%|
|Player may not double after splitting||-0.14%|
|Player may double on 10,11 only||-0.18%|
|Dealer hits on soft 17||-0.22%|
|Blackjack pays 7-5||-0.45%|
|Blackjack pays 6-5||-1.39%|
|Blackjacks pay 1 to 1||-2.27%|
I also have a longer list of rule variations.
Beware Short Pays on a Blackjack
More and more tables are showing up that pay less than the full 3 to 2 on a blackjack. Most of these tables pay 6 to 5, but some even money and 7 to 5 tables are known to exist. I would estimate that 10% of "21" tables in Las Vegas now pay less than 3 to 2. In my opinion, only games that pay 3 to 2 deserve to be called "blackjack," the rest fall under "21" games, including Super Fun 21 and Spanish 21. Regardless of the other rules, you should demand nothing less than 3 to 2 blackjack. You should always check the felt to be sure, and if the felt doesn't say, look for a sign. If nothing says the win on a blackjack, then ask.

Three popular bad strategies encountered at the blackjack table are: never bust, mimic the dealer, and always assume the dealer has a ten in the hole. All three are very bad strategies. Following are my specific comments on each of them, including the house edge under Atlantic City rules (dealer stands on soft 17, split up to 4 hands, double after split, double any two cards) of 0.43%.
Never bust: For my analysis of this strategy I assumed the player would never hit a hard 12 or more. All other decisions were according to correct basic strategy. This "never bust" strategy results in a house edge of 3.91%.
Mimic the dealer: For my analysis of this strategy I assumed the player would always hit 16 or less and stand on17 or more, including a soft 17. The player never doubled or split, since the dealer is not allowed to do so. This "mimic the dealer" strategy results in a house edge of 5.48%.
Assume a ten in the hole: For this strategy I first figured out the optimal basic strategy under this assumption. If the dealer had an ace up, then I reverted to proper basic strategy, because the dealer would have peeked for blackjack, making a 10 impossible. This "assume a ten" strategy results in a house edge of 10.03%.

Reason #1 why the Wizard likes Bovada:
Excellent customer support
The thing that separates Bovada from the rest is its customer support. Many other online gaming companies outsource their support. It can be difficult getting a response from them, and if you do it is often slow and handled by somebody with little understanding of gambling or even of English. But Bovada’s support is handled by Bovada, and their support staff is actually knowledgeable and helpful.
I’m so confident that you’ll have a good experience with Bovada that if you have a problem getting paid and you can’t resolve it with them on your own, I’ll talk to them myself. I personally have known the Bovada management for about three years and always found them to be professional, friendly, and knowledgeable. I have also personally visited one of their call centers so I could see first-hand how they handle customer issues. (More on my mediation service.)
If you have a problem with any other casino besides Bovada, I can’t help you. I get complaints from players of other online casinos every day who have difficulty getting paid. However that isn’t my job nor my problem. If you play at Bovada after clicking through my site I’ll stand behind you 100%. Any place else and you’re on your own.
