Blackjack Strategy

Should we split the pair?

In the basic strategy of Blackjack, split is recommended.

But some players seem unwilling to do it, and stand on the hand just as 14.

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

▼Experiment 1▼

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

Next, I took the same experiment 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.

It's easy to memorize the losing probability. (Just 1/2)
As a special note, the player won triple or more 11 out of 100 times.
For example, three wins at one doubled hand & one single hand, etc.

Standing on two 7s means standing on 14.
The graph also shows the probabilities of standing on 14 against D's 2.
We would lose at a rate of 2/3.

The results except for a tie

are as follows:

Winning Percentages
Split 45%    Stay 34%

The chip's fluctuation
Split -3 chips    Stay -32 chips


To sum up, splitting 7s against Dealer's 2 is preferable to standing on two 7s.


That's all.
I need to update another article now.
I hope this article will be useful.
Bye.
