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! To beat the dealer the player must first not bust (go over 21) and second either outscore the dealer or have the dealer bust. 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.
