June 27th, Sunday. This is not a day that should be played out, but it is indeed a day to play out - because this is what Conan asked for.

Yes, Conan took the initiative to apply for leave, and he also asked Qian Yu and Haibara Ai to also apply for leave - in the end, Genta Ayumi and Mitsuhiko also asked for leave despite the fact that the exam was only half a month away.

.

When Qianyu asked Conan why he did this, Conan didn't answer him with anything valuable, he just said he wanted to go out and relax.

————On the JR express train. Dr. Agasa and all the members of the Junior Detective Team were sitting in the car.

"Why not Himeji Castle?" Genta asked. "Since we are going to the castle tower, wouldn't it be better to go to the more famous Himeji Castle?"

"Egret Castle was listed as the first World Heritage Site in Japan by UNESCO last year (author: 1993 review, historical facts). It must be crowded now," Conan shrugged. "And Matsumoto Castle also has its own advantages, after all.

It is the only complex connected castle tower.”

At the same time, a more basic-level science popularization activity was taking place quietly on the seat next to him.

[The castle is a top-notch Japanese castle that appeared in the 16th century. The currently recognized originator of the castle is probably the Azuchi Castle built by Oda Nobunaga... It should have been built in 1576. Before that, there were some mountain castles or four-story oars.

It is still open to debate whether the analogues of the castle are considered castles.】——Qian Yu’s text message

[Is the castle in your wording a castle in the traditional European sense? Castle?]——Haihara Ai’s text message.

[It should not be counted, because the gap between the definitions of a castle and a castle is quite large. The castle itself is a comprehensive building integrating offensive and defensive capabilities, and serves as a garrison station and a fortress; while the castle is positioned as a defensive fortress.

In addition, it is mainly used to store supplies in places like the castle tower (if there is one) or to perform reconnaissance duties like the castle's predecessor - the oar. In short, I think the castle itself is roughly equivalent to Salzburg

A standard castle like a castle, but the castle itself is more like an inner fortress.】——Qianha

[Including that kind of defensive ability?]——Haihara Ai

[It’s hard to say this. After all, the inner fortresses in Europe are all made of stone. It’s a pity for the castle in this regard.]——Qian Yu

"By the way, how long will it take to arrive?" Yuantai asked. "I can't wait!"

"We've just started driving," said Dr. Ari, a little confused. "No matter what, it will take three hours to get to Matsumoto City."

"Then let's play a game I heard about now," Mitsuhiko suggested. "It's a good game to train your thinking skills!"

"?" Everyone looked at Mitsuhiko.

"One of us, as the question maker, proposes a puzzle," Mitsuhiko introduced. "When others ask questions in order, the question maker can only answer 'yes' or 'no' until someone can finally solve it.

Until this puzzle - of course, the premise of all this is that the puzzle cannot be too excessive, including excessive in every sense."

"If this is the case, it can indeed broaden lateral thinking very efficiently..." Conan pondered for a moment and said. "So, who will ask the question first?"

"How about I come first and give you a demonstration?" Dr. Ali suggested.

"Okay, then Doctor, you go first!" Mitsuhiko nodded. "But it can't be too difficult!"

"Okay, please listen to the question!" Dr. Ali said with a smile. "I remember I just taught you how to play Texas Hold'em poker last Thursday, right?"

"Yes!" Ayumi nodded. "That time Genta kept losing from the beginning to the end!"

"Why do you always remember such things, Ayumi!" Genta pouted, dissatisfied.

"Just remember how to play," Dr. Ali continued with a smile. "In a world-class Grand Prix final, two players were playing Texas Hold'em. Player A's last cards were k, q.

, q , q, q; and player B’s last cards were five cards that were not completely consecutive and did not have a. But in the end it was player B who won the game. May I ask why?”

"Ah?" Everyone was stunned at the same time.

The five cards q, q, q, q, and k are four-of-a-kind cards in Texas Hold'em. Only a straight flush and a larger four-of-a-kind can suppress this card type. However, the five cards in B's hand are not completely consecutive.

It is impossible for the cards to form a straight flush deck in any case. If there is a K in A's hand and there is no a in B's hand, there is no way for a four of a kind to be greater than the four of a kind in A's hand... What's going on?

"Okay," Dr. Ali seemed satisfied with their confused expressions. "Let's start answering!"

"Is this final a best-of-three game that allows one loss?" Ayumi asked first.

"No!" Dr. Ali didn't seem surprised by Ayumi's answer, but simply dismissed her idea.

"Is this a competition to see who has the smaller card?" Mitsuhiko asked.

"no!"

"Is there any secret behind the game?" Yuantai asked.

"No!" Dr. Ali said this and looked at Conan. "What do you think?"

"Is there only one deck of playing cards in this game?" Conan asked after thinking for a while.

[Yes! If there is more than one deck of playing cards, the cards in B's hand may be cards like kkkkq! According to the rules, such a four-of-a-kind is a larger combination than qqqqk. However, it is really possible to have multiple decks of cards.

Really? I’ve never heard of the card type “five of a kind” in Texas Hold’em before!]

"No!" Dr. Ali shook his head with an unconcealable smile.

[Sure enough, this idea is not very reliable, so why? 】

"Haiyuan, what do you think?" Dr. A Li looked at Haiyuan Ai.

"Doctor, please repeat the question." Haihara Ai just asked after thinking about it for a while.

"Ah? Oh." Dr. Ali was obviously stunned for a moment, and then repeated the question.

"..." Hui Yuan Ai frowned slightly, and then relaxed quickly. "Excuse me..."

“Is the qqqqk in hand A’s hand a four-of-a-kind card in Texas Hold’em?”

"Ah?" Except for Dr. Ali who raised his eyebrows and Haibara Ai who was waiting for the answer, everyone's eyes widened - what kind of question is this? If even the card type like qqqqk is not four.

, then what are four?

However, Dr. Ali gave them an even stranger answer.

"no!"

[qqqqa is not four? How can this be—wait a minute?]

Qianyu's surprised expression instantly faded away, replaced by a thoughtful expression, and a moment later he suddenly realized.

【I see!】

"Excuse me," Qianyu looked at Dr. A Li and asked, "Are the cards in A's hand two pairs or three of a kind?"

Two pairs in Texas Hold'em refers to two pairs of identical cards and one single card among the five cards, while three of a kind refers to three identical cards and two single cards. Both types of cards are more likely than B.

The composed cards are much smaller.

"Yes!" Dr. Ali's face was filled with a smile of approval.

"Doctor, is it really good to play around with the pronunciation of q and 9?" Qianyu curled her lips. "He even added a k in front to trick us into thinking they are all q..."

(I should have said before that q and 9 in Japanese have the same pronunciation, so A actually just drew a deck like qq99k or qqq9k, which is probably not as big as B's)
