[Blackjack] Two 9s vs Dealer's 2



Blackjack Strategy

That's like 9-double.
Two 9s vs Dealer's 2 in Blackjack

In the basic strategy of Blackjack, split is recommended.
But some players stand on the pair as hand 18.
They might think of the splitting as a risky gamble.

Then which choice is better to win?

I conducted a Blackjack experiment to calculate the winning percentages for both choices.
(without recording on video this time)
Blackjack Experiment Recording

Results of the experiment

The following graphs show the results based on the 100 data.
Blackjack Experiment Result of split (99 vs D2)
The winning rate is so-so.

Blackjack Experiment Result of stay (99 vs D2)
The result is rather good as I expected.


The results except for a tie 

are as follows:

Winning Percentages
Split 49%    Stay 60%

The chip's fluctuation 
Split +6 chips    Stay +18 chips
(Bet amount: 1 chip every time)

To sum up, stay is more preferable to split, contrary to the BS.


Lastly, look at this graph.
3-unit win in the case of 99 vs D2 in Blackjack
For example, after splitting, one is a doubled hand and the other is normal.

And then, if the player wins all, we call it 3-unit win.

In this experiment, he won triple at a rate of 70%.
That's a positive aspect.

This video consists of some examples of the 3-unit bet (both win and loss).
If you're interested, check it out.
The playback time is only a few minutes.


That's all.
Hope this article will be useful.
If you like, give me comments, thanks.
Good luck for your splitting.
Bye.
