Cheng Jinzhou has never practiced blackjack card counting, but he knows a lot about its principles.

In fact, blackjack card counting is a simplified probability calculation process. Its principle is to calculate the player's probability of winning based on the cards on the card. Under this guidance, an average win can be obtained - that is, if the game is long enough, success will be achieved if there is a certain winning rate.

For example, when the card in the player's hand is 11 points, since the largest card among all the cards is only 10 points, the probability that his next card will not explode is 100%, then he will undoubtedly choose to add a card, and when the player When the card in hand is 12 points, the probability of the next card not exploding is reduced to 69.4%, and when the next card is 13 o'clock, the probability of the next card not exploding is 61.5%.

The dealer's disadvantage is that below 17 points, he must ask for cards, and when 17 points and above, he must suspend the cards. In fact, the dealer himself has no judgment.

The most basic form of card counting is to take all these probabilities into account and then sort them out to give a direct answer. For example, at 10 o'clock, you need cards, and at 12 o'clock, you should also need cards, and so on.

Of course, the actual problem is much more complicated, but the basic idea is so simple.

If it were Cheng Jinzhou in the past, even if he knew this principle, without three or two years of research, it would actually be difficult to use it in the casino. After all, facing the different probabilities of both parties, and then analyzing it, it would take at least dozens of minutes. , the dealer can't always wait for you to calculate.

For the astrologers of this era, it is one thing for them to be able to understand probability. It is completely impossible to fully apply probability to blackjack card counting. Even in China in the new century, it is impossible to do so. There are not many mathematicians working on such topics.

Not to mention gentlemen who haven't even figured out probability itself.

But to put it another way, for example, the binary machine "George" that can calculate by itself does not use any modified card counting, but usually directly uses probability to calculate. Because of this, the cigarette box big machine The little guy's shell would often overheat and burn out, eventually wiping out the entire Ken O'stone team - they were one of the few card counters to be caught in prison.

Cheng Jinzhou felt that he might not be able to achieve the high speed of a computer, but with the existence of elementary mental arithmetic tutorials, it was not too difficult to do some calculations.

After all, in the 21st century, in order to reduce card counting as much as possible, casinos use 8 decks of cards to be shuffled and cut off one and a half decks, but today's church priests only use two decks of cards.

And they are just like the original blackjack players, using both decks of cards to the end. This method was no longer used in Las Vegas casinos by the 1970s.

Cheng Jinzhou silently thought about some probability formulas, and continued to count ten taels and twenty taels of silver, trying to calculate again and again.

Mu Yin looked at Cheng Jinzhou with more and more discrimination. He had about 1,500 taels of silver in his hand, which was equivalent to 400,000 yuan. It was already a lot to carry with him. Especially compared with Cheng Jinzhou's 50 taels of silver each time, his bets are much larger, at least 100 taels of silver each time. If he encounters the same cards, he will often split the cards, which means that Two decks of cards double the bet.

Cheng Jinzhou didn't understand why the other party disliked him, but that was the way it was, so he simply pretended that he didn't know the two of them and made preparations.

He is now at least 60-70% sure that he can maintain a winning rate of more than 2%. If he is lucky, a winning rate of 3% is also possible. In this case, as long as the betting amount reaches 400,000, he can basically win 1 Ten thousand taels of silver.

If you don't want to make a profit and just spend the money on hand, betting 1,000 taels of silver per bet will be very fast.

After looking at a few more chips, Cheng Jinzhou determined that there was no risk. When the priest reshuffled the cards, he threw the largest wooden chip at hand on the table.

1,000 taels of silver.

Mu Yin said "Hey" and said sarcastically: "Did you throw the wrong one?"

Cheng Jinzhou nodded to the pastor and curled his lips slightly towards Mu Yin.

The young man couldn't stand the excitement. Mu Yin's head got hot and he threw in all the 10 hundred taels of chips on his table.

"Fourth." The man Shi Qingshan, who was sitting opposite Cheng Jinzhou, looked a little unhappy and said, "Don't let others lead you."

"Brother. Is he sure of winning?" After Mu Yin said this, Shi Qingshan Man also said nothing.

These astrologers who gamble in the Holy Religion are either interested in gambling, or they just want to obtain some resources from the Holy Religion. With some mathematical skills, as long as they are careful, they will probably not lose too much, but they may not lose too much. Don't think about winning money. As for a sure win, the more self-righteous mathematicians think it is impossible.

After all, their research on probability is not deep enough.

There was a sneer on Cheng Jinzhou's lips. Of course he didn't just enter the game casually. Because the priest will deal out the cards every time, and turn over all the cards after each time, so if you are good at remembering the cards, you can easily know how many big and small cards there are in the remaining cards.

The remaining cards are called shoe cards in casinos. With more big cards, the casino has a smaller chance of winning. Therefore, in modern casinos, players are usually not allowed to join the game in the middle of a round, but they cannot stop it. Gamblers raise their bets.

If you reduce the bet on the upper shoe card and increase the bet on the lower shoe card, in the long run, the probability of winning may even exceed 20%. However, when the number of cards increases to 8 decks, learn two decks and only use half of them at the same time. In this case, the advantages of shoe tags will be lost again.

However, these offensive and defensive stories between casinos and players will only attract the attention of casinos if they actually happen. Gentlemen who have never experienced it don’t know how powerful it is.

In the first game, Cheng Jinzhou got 14 points, and the dealer's face card was 7. The player's chance of not blowing is 53.6%, and the dealer's chance of stopping between 17 and 21 is 75%.

"Continue." Cheng Jinzhou tapped the weight on the table twice.

Xue Yin got 12 points and said without any sign of weakness: "Continue."

Others at the card table just smiled and let the dealer deal the cards.

Cheng Jinzhou successfully got 5 points, and naturally stopped trading at 19 points.

What the dealer got was an 8. If nothing else happened, he might have exploded.

Under this situation, the man in green shirt, Cao Feng and others lost their cards one after another. Xue Yin looked at his 17 points, but waved his hand with some pity: "Continue."

The pastor silently handed him a 7, then raised his hand and said, "Explode."

Cheng Jinzhou couldn't help but laugh.

"The banker blows, and the general compensation is paid." The pastor turned over his cards, and then paid Cheng Jinzhou 1,000 taels of silver.

Mu Yinze didn't make any money. Both sides exploded, so naturally it was the banker who took the money. This is also the bookmaker’s biggest advantage.

Next. The pastor played another game with the cards in his hand. Cheng Jinzhou threw in 1,000 taels of silver and still won. It was completely different from the results he had received dozens of times before, but it attracted more people's attention.

Mu Yin followed two rounds without believing it, one for 1,000 taels and one for 500 taels. He lost both rounds and his face turned green immediately.

He is not only unlucky, but more importantly, he does not follow the rules - in the blackjack winning method, the best expectation is that the dealer blows up, and the second expectation is that he has more points than the dealer. There is never any expectation. You have more points than other players.

However, the star warlock didn't have much silver in his hands, but he didn't care about money very much. The anger on his face was probably for Cheng Jinzhou.

"Do you still have any bets?" Cheng Jinzhou also lowered his head and began to calculate. He would write down some commonly used numbers on paper to increase efficiency.

Mu Yin waved his hand to borrow money, but was interrupted by his elder brother: "In Shimodian Shimin, let's get to know Mr. Cheng again."

Obviously, Cheng Jinzhou's accurate bet surprised him.

In the Holy Church's casino, any kind of game requires skills, especially mathematical skills. This is also the focus of the gentlemen of the Holy Church. Tian Shimin played at the blackjack table for a long time, but he didn't see Cheng Jinzhou's methods, so he was naturally curious.

"Hello." Cheng Jinzhou shook hands with him across the gambling table and asked in a friendly manner: "My brother seems to be quite dissatisfied with me?"

Now that he has both the warlock Cao Fengxing and Lu Xu, he is naturally confident and speaks with a bit more forcefulness. In the final analysis, it is the factor of playboys bullying the weak and fearing the strong.

Tian Shimin did not expect Cheng Jinzhou to be so direct, so he smiled bitterly and said: "Since you have asked, I will tell you frankly that my fourth brother Mu Yin and Zhao Quanfu are cousins, and they have always played well. So. …”

After Zhao Quanfu came to the capital, apart from his original grudge against Cheng Jinzhou, he had not had time to forge any other grudges. Others are justifiably skeptical. In fact, if it weren't for Cheng Jinzhou's identity as a two-star warlock, he would have been forcibly captured and interrogated by people from the Ministry of Punishment last time.

When they finished talking, Mu Yin also turned around and said in a very tempered manner: "The recent events have nothing to do with you."

At the same time, Mu Yin stared at Cheng Jinzhou with vicious eyes.

Xiao Cheng said "Oh" without changing his expression, and said to the dealer who was watching the excitement: "Let's continue dealing the cards. I won 2,000 taels of silver, so I have 4,000 taels of silver to buy things?"

The dealer seemed to have just woken up, and after a while he replied: "That's right."

"Is there a star array I can buy for 4,000 taels of silver?"

"Level 0 Throwing and Wind Transformation Techniques should both be below this value." The dealer thought about it and explained: "They are both the most basic star formations. Throwing Techniques can allow you to use star formations and so on. , the judgment of the direction is more accurate, and the Wind Transformation Technique can blow some breeze. The wind speed is low, but it can blow some medicines and other things."

Mu Yin's eyes hurt from staring, and he just waited for Cheng Jinzhou to say "Oh", his anger level instantly increased, and he interjected: Throwing a star array requires more than 8 star points, so I don't believe you can use it. "

The one who can withstand 10 star points is a first-level star warlock. Cheng Jinzhou has not chosen the star array now, and he doesn't have 8 star points available. In fact, even if there were, it would be impossible to use all the star points to support a supporting star array.

"50 taels." Cheng Jinzhou left a wooden sign on the table and said calmly: "Zhao Quanfu is a little bastard. If he dies, he will die. What does it have to do with me. Don't mention this in front of me in the future. name."

The dealer continued to deal the cards, and Mu Yin also threw in the few remaining weights in his hand, secretly observing Cheng Jinzhou's movements.
