Blackjack Strategy

Expect doubling down will come after splitting it.

In the basic strategy of Blackjack, split is recommended.
However, it's applicable to this rule: double after split is allowed.
What about hitting the pair as 4?

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

▼Experiment 1▼

▼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.

▼Detailed Result 2▼

These two graphs show 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 lose at a rate of about 1/2.

There is not really a big difference between both results.

The results except for a tie

are as follows:

Winning Percentages

Split 47%    Hit 47%

The chip's fluctuation

Split +2 chips    Hit -6 chips

One more thing, look at this graph.

It shows the percentages of 3-unit-win.

At a rate of 62%, the player won triple.

For example, after splitting, one is a doubled hand and the other is normal.

And then, he won both.

This is a positive aspect brought by splitting.

This time, there was no 4-unit-win nor 4-unit-loss.

To sum up, against Dealer's 2, split a pair of 2 is rather preferable to hit it.

That's all.

Hope this article will be useful.

If you like, give me comments, thanks.

Good luck for your splitting.

Bye.
