Blackjack Strategy

Shout, "Picture!" when your card is being dealt.

In the basic strategy of Blackjack, double down is recommended.

But some players make a defensive decision.

They choose hit, not double down in this situation.

I conducted a Blackjack experiment to calculate the winning percentages for both choices.

▼Detailed Result 1▼

The following two graphs show the percentages of each outcome based on the 50 data.

To get more precise result, I collected more data under the European no hole card style.

▼Experiment 2▼
In this video, Japanese language is mainly used, but you will vaguely understand how the experiment proceeds.

These two graph shows the percentages of each outcome based on the 50 data.

More Precise Result

Lastly, the following two graphs show the results based on the 100 data.

We would win at a rate of about 1/2.
Compared to other doubling down, the rate would be lower.
What about doubling down if you could guess the next card is 10.

There is not really a big difference between both results.

The losing percentage includes some busted hands.

If you really dislike the bust, I recommend you choose double down.

The results except for a tie

are as follows:

Winning Percentages
Double Down 51%    Hit 52%

The chip's fluctuation
Double Down +9 chips    Hit +3 chips


To sum up, it is difficult to say clearly which choice is better to win.
Why don't you choose double down if you feel it's a lucky day for you?


That's all.
I hope this article will be useful.
