[Pontoon,Spanish 21] 14 vs Dealer's 2


Pontoon (Spanish 21) Strategy


Isn't it difficult to hit hard 14?
hard 14 against Dealer's 2 in Pontoon

In the basic strategy of Pontoon, hit is recommended.
But most players would choose stand on it as in Blackjack.
I don't understand why the BS says hit.

I conducted a Pontoon experiment to calculate the winning percentages for both choices.
In the video, the number of trials is 20.
After recording it, I collected more 80 data.

Results of the experiment

The following two graphs show the results based on the 100 data.
Pontoon Experiment Result (14 vs D2)
Although this game is Pontoon and we don't use 10's cards, the winning rate is despairing.
The graph may imply that the winning rate in Blackjack is worse than the one in Pontoon.
So we should definitely stand on hard 14 against D's 2 in Blackjack.

Pontoon Experiment Result (14 vs D2)
This graph shows not only the winning rate, but also the probability of the dealer's busted.
In brief, the dealer's hand busts at a rate of 30% if he starts with 2.
In addition, we could expect the dealer's hand to bust more than in Pontoon.


The results except for a tie

 are as follows:


Winning Percentages
Hit 30%    Stay 30%


To sum up, it is difficult to make a decision on which to choose, hit or stay.

I have a good suggestion.
What about hitting 4 or more-card-14, 6&8-14, etc?
If we can take a card of 7 in those situations, we will get some bonus chips.

Bonus Chance 1    4-card-14

Bonus Chance 2    6&8-14

Bonus Chance 3    6&8 with spades-14

As far as I know, under Aussie style,

the odds are 3 to 2 at 5-card-21, 678-21, 777-21.

the odds are 2 to 1 at 6-card-21, 678 (same suits)-21, 777 (same suits)-21.

the odds are 3 to 1 at 7-card-21, 678 (spades)-21, 777 (spades)-21



However, the house is needed to be religious for players.
If you can see a 6-5 blackjack table, I guess you couldn't find any good Pontoon table.


That's all.
I updated twice today.
Enjoy your Pontoon.
Take care.
