Chapter Ninety-Three

Blackjack!

It is one of the most mainstream poker games in casinos at present.

The rules are simple.

At the gaming table, there are bankers and players.

At the beginning of each hand, the dealer deals the cards.

The banker and player each have two cards.

Among them, the two cards of the player are face-up, that is, the numbers on the two cards are visible.

And the dealer's two cards, one face up and one face down.

The player can only see the number on one of the banker's cards.

After the cards are dealt, the dealer asks the player if they want to get the cards.

If the player hits, the dealer deals him an open card, and then repeats the previous step of asking if he wants to deal.

If the player chooses to stop hitting, the game stops and progress points are determined.

............

Blackjack is a game that requires a total of 4~6 decks of playing cards.

In the calculation of points, A can be used as one point or eleven points, 2 to 10 as the value of the card, and J, Q and K as ten points!

When the player is in the process of playing cards, the number of cards in his hand, more than 21 points, it is called "bust"!

Once this happens, the game ends immediately and the player pays out all bets to the banker.

And it is not difficult for the player to win money from the banker.

As long as you make sure that the value of the cards in your hand exceeds the value of the dealer's cards, and the sum of the cards does not exceed blackjack!

The same is true for the banker, who wins with a higher number of points than the player and without the cards being busted.

Of course, it is important to note that the player loses if he busts first, even if the dealer busts later.

If the player and dealer have the same number of points, neither the player nor the dealer will win or lose, and the game will be a tie.

One more point, which needs to be noted.

During the entire blackjack game, the dealer has no decision.

That is, after the player stops hitting, the dealer opens another face card, if the sum of the face card and the face card points, less than or equal to 16 points, then the card must be a card.

If the value increases to 17 points, you must stop hitting!

It is not the same as the player, who can choose to hit or stand.

Since it was only Gu Lu and the bald man who played, the bald man only took four decks of poker rackets.

Tearing open the packaging of the four brand-new decks of playing cards, and then throwing away the big and small kings in each deck of playing cards, the bald man pushed a total of 208 cards to Gu Lu.

"Little brother, check it? I'm a serious place, and I won't play with those yin things. ”

Serious place?

Gu Lu couldn't help but be happy for a moment, and then checked the four decks of playing cards.

It's really no problem, the 208 cards are all brand new, and there is no possibility of marking, otherwise the bald man would not be confident enough to check himself.

"No problem. Gu Lu pushed the playing cards back to the bald man.

"Since it's okay, then little brother, let's get started!" the bald man smiled, slapped a stack of cash on the table like Gu Lu, and then put the playing cards into the card machine.

Money!

It's all money!

At this moment, the bald man's attention was completely focused on the stack of banknotes beside Gu Lu's hand, his eyes greedy.

can come up with 10,000 yuan so easily, he must be a fat man!

If you don't slaughter it well, bald men feel ashamed of their professional ethics.

Blackjack is a game, although at first glance, the probability of the player and the banker winning or losing is five or five.

However, in practice, the probability of the banker winning is much higher than that of the player.

Because the dealer asks for cards in the back hand, the player bursts before, and the banker wins directly.

If the player doesn't explode, the banker will still win as long as he outperforms the player in points.

According to the bald man's experience for many years, in the game of blackjack, when two people play, the winning rate of the banker and the player, seven or three is the correct value.

Ten handfuls, he can win three.

In less than half an hour, the 10,000 yuan in front of Gu Lu would flow into his pocket.

............

Gu Lu took out two hundred yuan from the pile of money and put it in the betting area.

"Let's start dealing cards!" Gu Lu glanced at the bald man lightly, and the corners of his mouth rose slightly.

Blackjack!

Gu Lu felt a little nostalgic.

Since being blacklisted by the casinos in the United States two years ago, Gu Lu has not played for a long time.

In the world of mathematics, there has always been a warning.

If you're not a pro, don't compete with mathematicians about two things, one is chess and the other is cards!

Because mathematicians will use their solid professional knowledge to let you re-understand what is called real ...... from beginning to end Board games!

Why are there so few casinos open near those top international universities?

It's not because the filthy and turbid environment of the casino pollutes the noble and pure hearts of those students in the ivory tower.

It's the group of casino owners, who are afraid of being taught by students and teachers in colleges and universities!

In particular, the students and teachers of the mathematics department are a nightmare for major casinos.

In casinos, card gambling plays a large proportion.

Mathematicians, on the other hand, will easily find the loopholes in the gameplay and then calculate a strategy that is almost guaranteed to win.

There was once a bad boss who opened a casino in the small town where Princeton University is located.

As a result, one day, an old professor of mathematics at Princeton University was taking several of his students for a walk in the small town of Princeton when he discovered the newly opened casino.

"Wow, there's a new casino here! Sexy dealers, deal cards online!"

"This boss is a little young! Come on, students, let's teach the young boss a lesson!"

The old professor waved his hand and led the students into class.

The casino owner, who was taught a lesson by everyone in Princeton's math department, closed his doors and left this sad place the next day.

At the same time, the Princeton teachers and students who participated in the class that night were also blacklisted by major casinos around the world.

............

Blackjack, this type of gambling, mathematicians have also found many loopholes that can increase the odds of winning.

In this game, the number of cards and the number of points are fixed.

And, as the game progresses, the number of cards gradually decreases.

The mathematician can calculate the remaining cards in the deck by "counting the cards".

Then, through probability calculations, the best winning strategy is found.

Take a chestnut~~

Suppose there are 25 cards left in the pile after the dealer and player have each dealt their two cards.

You have two cards in your hand, 5 and Queen, for a total of 15.

The dealer's face card is 3, and the face card is unknown.

Since no matter what the value of the dealer's other face card is, the maximum value of the two cards is 13, less than 16, and the hit card must be made.

At this time, you know the 25 cards of the pile, as well as a face down card in the dealer's hand, a total of 26 cards, of which the number of K, Q, J, 10 is 18, two 9s, one 6, one 4, two 3s, two 2s.

What is the optimal strategy for this situation?

That is, instead of hitting cards, let the dealer take the cards.

Because there is no need for too complicated calculations, it can be concluded that the dealer has a high probability of busting!

Of course, the above is a more extreme case.

In practice, the situation is often much more complex than this, and the optimal processing method cannot be seen at a glance so simply, but requires a rather complex calculation process.

However, this does not stump Gu Lu.
