His home attack always doesn't let him pretend

Qi Youhan is also a little nervous. He will be able to enter the semi-finals at about sub14. He is making steady progress, but after all, he has expectations for his three-speed results. Which step, the unknown and the wish, made him nervous.

Clutching a Rubik's Cube in his hand, he spun it with a thunderbolt, completely irregular, just doing formula tricks one after another like a conditioned reflex. How can a professional player who has ever been runner-up in the world be defeated by a small preliminary round? Qi Youhan is the one he likes.

Qi Youhan was still concentrating on adjusting his mentality, when two foreigners appeared beside Yue Mo and greeted Yue Mo softly.Qi Youhan turned his head when he heard the movement. He knew one of the two foreigners, and he was the one who slapped Fu Sheng twice.

When Andro saw Qi Youhan, he chirped out many words and wanted to shake hands with him. Qi Youhan was stunned instantly, and looked at Yue Mo as if asking for help while shaking hands.

Yue Mo was so cute by the expression of Qi Youhan's little milk cat, it was as cute as seeing a cat mat in front of him, couldn't help but want to pinch it twice, generously embraced Qi Youhan's waist, and translated for him: "He said that he and Oort are both in the third batch, so you can play well. The competition is fierce this time, and it is not easy to think of the top three."

Qi Youhan nodded. On the world record list this time, only two of the world's top three came, as well as Andro, the world's top ten, and five or six veteran Chinese top players Wang Yan and Li Zhitao. They are all people who have stood on the podium of the Regional Open and China Rubik's Cube Championship. Qi Youhan wants to win the medal not only depends on strength, but also luck. This battle is not ordinary.

But Qi Youhan is not afraid.

Seeing Yue Mo hugging Qi Youhan, Oort also chirped a few words, Yue Mo laughed and pecked Qi Youhan on the cheek.

Qi Youhan: "..."

The few people spoke very quietly, but they didn't attract much attention. Yue Mo simply translated it for Qi Youhan: "I told them that you are very talented, and they said they expect you to show good results and stand on the final stage together."

"Definitely!" Qi Youhan replied quickly. Even before he was sealed off, he had a great hope of reaching the final with his sub9 strength. His goal is not limited to the final. If he wants to win the championship, he will do his best effort.

After the first batch of competitions in the preliminary round, it was Yue Mo's turn to play. Yue Mo probably greeted Oort and Andro. The two knew that Qi Youhan was not very fluent in English, and they used very common words when communicating with him. .

Andro: "You really look pretty."

Qi Youhan understood, and then he became unhappy: "I am handsome, not pretty." How many times have I said it, I am handsome, not pretty!

Andro: "Beautiful."

Qi Youhan said with a straight face: "Handsome."

Alter: "Cute."

Qi Youhan squeezed out a smile, I must have screwed you today, believe it or not.

The second batch of races ended soon, and finally it was Qi Youhan's turn in the three-speed race for the first time in his life. Before sitting on the designated seat, Yue Mo, who was in a hurry, pulled Qi Youhan's left hand and rubbed him: "You don't need to save your strength, just do your best."

"Huh?" The weather was not so good today, and Qi Youhan's muscles were a little stiff. He did his own warm-up, but he always felt that there was something missing. Now that Yue Mo rubbed it, the missing part was filled in an instant.Pursing his lips, the smile on his lips finally showed.

Oort and Andro on the side were sprinkled with dog food.

"Why is there dog food?"

"I don't know, the Chinese are so strange!"

After Yue Mo finished rubbing, he patted Qi Youhan's butt: "Go, remember that today's audience will get an extra 1 yuan bonus at the fastest."

Qi Youhan frowned, there is such a good thing!

The Rubik's Cube competition is not like the Olympic Games. The preliminaries and rematches do not consume much for the players. For a project that can be practiced for eight hours a day, the players do not have the trouble of how to allocate their physical strength.

In addition, in the official world record of WCA, every result of every game is recorded.There are many records that were not created in the finals. For example, Feishen's 6.45 world number one was achieved in the rematch of WLSLato2016.

So it doesn't mean that players can relax a little in the preliminary round, and if they relax for a while, what they lose may be the opportunity to create records and break through themselves.

All the contestants tried their best to participate in the preliminary competition. This is a unique scene of the Rubik's Cube competition, and it is also the unique charm of the Rubik's Cube competition.

Qi Youhan is the first in the second row, and Oort is just to his left, the second in the second row.

These two positions are arranged very delicately, and I don't know if it is a coincidence.Qi Youhan once vowed to compete with Oort in the Shanghai Open after the "Brain King" program. He wanted to surpass Oort and prove his own strength. The captains realized how stupid they were, and now, in the preliminary round, this opportunity was already in front of Qi Youhan.

Qi Youhan closed his eyes and took a deep breath. When he opened his eyes again, the focus and expression in his eyes was like an international champion standing at the starting line. At this moment, Yue Mo knew that Qi Youhan was ready.

Referee: "Are you ready?"

Qi Youhan: "Okay."

The mask of the Rubik's Cube in front of him was opened, and Qi Youhan immediately picked up the Rubik's Cube to observe.

This is a state where the white-green edge block at the bottom is already in place. When the orange side is facing itself, the white-blue block is on the fr side (front right), and it can be returned to its position by just doing an r', but in order to reduce steps, Generally, the white and red blocks with the reversed positions of the bottom color blocks are turned up and turned to the same side of the white and blue blocks, so that when the blue blocks return to their original positions, the red blocks can be placed in a position that is easier to restore.

At this time, the red block and the orange block are facing each other, as long as the middle edge block is turned 180 degrees, the cross is done, and the steps are the fewest.

Most of the players would do this, which is also the main idea of ​​the cross, but Qi Youhan suddenly discovered that if he took two more steps, he would first turn the orange block away, turn to the r edge where the blue block is, and then turn the red block up , using the action when the blue block is homing, the orange and red blocks can form a 90-degree angle. Here, it takes four steps to return the red block and the orange block to their respective positions, which is two more steps than before, but this way Come on, the next f2l will be very easy with two groups!

Complete the cross with the fewest steps. The first group of f2l can restore the edges and corners of the red and blue slots with formula 8 in 32 steps, or restore the angle between orange and blue with formula 7 in 36 steps, but it is vague I feel that according to the second cross solution, the first group of f2l only needs to use the third and simplest four-step formula to complete, and even at the same time of completion, the second group of f2l color blocks can also be adjusted to a comparative comfortable location.

Qi Youhan was not sure, this was the first time he had such a premonition.

He even saw that the third group was most likely the fifth group among the 12 groups of f2l solutions. Many players who played the Rubik's Cube used "far cut back to pick up the children from school" to memorize the restoration formula of this group.

f2l is a method to combine the corner blocks and edge blocks of the bottom layer and the middle layer into a group and restore them together. The formula of the fifth group is used when the corner blocks have been restored, and the corner blocks of this group, It is not in the position now, but according to Qi Youhan's idea, it can be restored when Qi Youhan imagined the second cross plan, which is to do the two steps of turning the orange block away first.

The formula of "far cut back and back to pick up the child from school" is the basic formula. It has been learned in the layer-first method, and beginners must be very familiar with it, because it is the first formula that was contacted when restoring the second layer. Qi Youhan did it very smoothly , u(ru'ru'(f'uf) these 8 steps, Qi Youhan can complete in half a second.

Calculated in this way, if you do a few more steps in the cross, the time you can save in the f2l later cannot be estimated specifically, but it must be a lot!

"8 seconds." The referee reminded.

Qi Youhan blinked, wondering if he should try it.

This is the first time he can see so far in a cross. He is not 100% confident in his judgment. He knows that if he solves such a Rubik's Cube in 8 seconds or It was restored at the end of 7 seconds. This result is considered very good in the regional open.

However, if the prediction is wrong, the recovery time will exceed expectations. Although he has an intuition that he can make progress, he cannot rule out the possibility of a wrong judgment.During the period when he encountered a bottleneck, he often encountered such a situation, and his intuition usually only had the opposite effect.

But this time Qi Youhan felt different...

Do you want to try it.

"Stop." The referee reminded again.
