For blackjack players who play according to basic strategy, I know, this myth does not make any sense.
And players believe this regardless of whether they are playing online blackjack or blackjack in a brick and mortar casino. Some are absolutely steadfast in this myth.
In truth they are only hurting their own blackjack odds.
Here is what happens in the mind of blackjack player who believes this myth—this is their reasoning. They are afraid of hitting and receiving a 10. They believe that the dealer’s hole card is a 10—another no-no in blackjack—and that if the dealer was dealt a 2 and a 10; and if they stand then the dealer will receive that 10 and bust.
They have this idea that if they hit they will only receive a 10. In their mind there is no other card that they could receive. So they will stand and hope the dealer gets the 10.
But here are the odds: standing on a hard 12 against a dealer’s 2 will cause you to lose 65% of the time while only winning 35% of the time.
On the other hand, if you hit like basic strategy tells you to, you will only lose 63% but you will win 37% of the time.
Yes, in the long run the odds are against the blackjack player in the long run. But look at the winning percentages: you will win 37% of the time if you hit. That is 2% more than if you were to stand. Granted 2% is not a lot, but I will take that 37% chance of winning rather than give it up.
Besides believing that you can only hit a hard 12 and receive a 10 in blackjack just seems, well, rather limiting. It also sounds a little like chopping off your nose to spite your face blackjack style.
