Chapter 189 Blackjack Decisive Victory

The games played by Miaomiao, Azhi and Mr. Benny are very simple, which is the most popular "21 o'clock" nowadays.

The dealer deals two cards to each player, one face and one face.

Players decide whether to take a third card based on the points added by the two cards.

The sum of the points of all cards is compared to the size, 21 points is the largest, and if it exceeds 21 points, it will be blown and cleared.

The tavern is actually a casino. People sitting around the table will inevitably have to gamble two hands when they are drunk. "Blackjack", which only needs a deck of cards and has simple and rough rules, is the most popular game in the bar room.

Compared with the games at the adjacent table where people bet wildly, sometimes people lose their underwear and even fight big, the game where Xiao Miao and others use French fries as chips, and the loser only needs to buy the winner a glass of beer can be called a small gamble. hurt peace.

Teacher Benny invites Joan to play together. Joan frankly admitted that he didn't understand the rules of playing cards, so he just watched them play from the sidelines.

As a simple kid who was taught by his grandfather to stay away from the gaming table since he was a child, Joan had no interest in playing cards, but after observing a few hands and understanding the rules of the game, his brain with an intelligence attribute of 22 could not help but run at high speed.

In the eyes of Xiaomiao and others, playing cards is a kind of gambling game. Winning or losing is mainly based on luck, while poker skills are mainly reflected in the observation of words and expressions. Based on the changes in the opponent's expression, it is guessed whether he really has a good card or is just bluffing.

However, the poker table in Joan's eyes is a completely different world - a pure and fascinating world of mathematics.

In Qiao An's view, the "blackjack" game rules are actually calculations of probability under given conditions.

Whether the cards are good or bad is indeed determined by random luck. However, whether to choose to continue to ask for cards after getting a deck of cards cannot depend entirely on luck.

Smart people should make the most rational decision that has the greatest chance of winning on the basis of probability calculations.

Joan sat at the table and watched the three play cards, silently calculating the winning probability corresponding to different card types.

After half an hour of analysis and comparison, he found an optimal playing strategy for "blackjack".

However, the secretly happy mood only lasted for a short minute.

After further analysis, Qiao An was disappointed to find that this strategy can only guarantee a 49% winning rate at most, which is not worthwhile in the long run.

Joan didn't give up just yet.

He was less eager to win the game than to solve a mathematical problem.

The current analysis is still only on the calculation of the cards in the hand. Joan soon realized that there is another type of data that has not been fully utilized, which is the pile of cards left after the dealer has dealt the cards.

Referring to the exposed cards in the player's hand, it can be inferred how many cards of various points there are in the remaining cards.

Joan uses a simple card counting method to divide cards of different points into big cards and small cards, and adjusts the game strategy according to the changes in the number of cards on the table. Roughly calculated, it can increase the winning rate by 2%.

Combining the two strategies, Qiao An's mathematical expectation of winning the game reached 51%, which is undoubtedly a qualitative leap!

But he was still not satisfied, and thought deeply about what data was available on the poker table to further improve the game strategy.

The cards themselves could no longer provide more valuable information, and the subtle expression changes and psychological games Joan valued by casino veterans were also useless.

After all, he is not a person like Mr. Benny. He lacks the understanding of the three religions, nine streams and all walks of life, and he is not good at inferring a person's true inner thoughts through expression changes. In the end, he still has to dig deeper from the purely rational mathematics field.

After a period of thinking, Joan finally found his "New World", which is the third type of data on the poker table that is different from cards and players - bets!

Next, what Joan has to do is to calculate the most favorable bet based on the winning percentage of the existing cards.

Fools also know that the better the cards in the hand, the bigger the bet, and vice versa. But when it comes to the precise formula of winning percentage and bet, few people can explain clearly.

It was inconvenient for Qiao An to take out a pen and paper to check the calculations. With an intelligence attribute as high as 22, he did mental calculations throughout the whole process, and it took half an hour to sort out the correlation formula between winning rate and bet.

Betting according to the formula can achieve the optimal strategy of "winning big and losing small" in the long run.

Of course, any poker game cannot continue indefinitely. Even if Qiao An sums up the best strategy, it is normal to lose underpants within an hour. After all, the smaller the sample, the greater the impact of luck.

"Sister Miao, do you want to continue to sit in the village?" Qiao An asked suddenly.

"I'm lucky, of course I want to continue to be a banker." Catwoman looked over in surprise.

"Can you count me in?"

"Interested in playing two?"

Joan nodded shyly.

"OK!"

Xiao Miao readily dealt him the cards.

Joan picked up the cards, and his clumsy appearance drew Xiao Miao's laughter.

But it didn't take long for her to stop laughing.

Joan seemed to be very lucky. The French fries on the plate in front of him quickly piled up into a hill.

Xiao Miao's chips went from bad to worse, and finally lost all after an hour, and threw down the cards angrily.

"Stop playing! I'm so mad!"

"Joan won the most, I really can't tell he is a novice." Teacher Benny said with a smile.

"It's not surprising. Novices on the gambling table will always have good luck. Otherwise, there wouldn't be so many people addicted to gambling. Novices always think that their good luck can last forever, but they don't know that it's all set by the God of Gambling. It’s a trick.” A Zhi was full of emotions, but he still didn’t forget to add the most crucial sentence: “Today, Xiao Miao treats guests, everyone let go of their bellies and drink!”

"I don't think it's all luck for Joan to win." Teacher Benny grinned, "If I'm not mistaken, he seems to have mastered a special card skill. Using this card skill, you can win as much as you lose."

"How is this possible?" Ah Zhi's eyes widened in disbelief, "If there is such a winning card skill, Joan doesn't need to do anything else, wouldn't it be easy to make a fortune by playing a few games a day? !"

"It is possible in theory, but in reality the bet is not always so fair. Even if Joan wins the bet with his superhuman card counting ability, the opponent may not allow him to take away the chips."

Teacher Benny smiled wryly and shook his head.

"Joan is very smart, but he is far from the only gambler who is proficient in card counting. Experienced gamblers will find that he is counting cards after a little observation, so don't take him to play. If it is in a casino, the situation will be even worse. Card counting Once they are discovered, they will be expelled at least, or murdered at worst. A young and promising mage like Joan will prosper sooner or later, so why bother to take huge risks to become a professional gambler."

When A Zhi and Teacher Benny were chatting, Qiao An's mood also fluctuated sharply with the content of the conversation between the two.

At first, he heard Ah Zhi talking about using card counting skills to easily make a lot of money, and he couldn't help but feel his heart skip a beat. However, after hearing Mr. Benny's pessimistic remarks, his heart was half cold.
