Champion players could receive more than 20,000 yuan in prize money, and they were given the opportunity to be awarded the title of amateur 6th segment. But on April 24th. In the morning, in the second round, Hu Xiaoqing, an amateur eighth-stage player known as "Amateur Chess King," was defeated by a not-yet-unique player Liu Chao. Hu was pulled by a friend after the game ended, referring to the netizen's discovery of Liu. The time spent in each step of the next game is almost the same, whether it is a difficult move or a simple move. Therefore, a friend suspects that Liu Chao used AI to cheat. After a friend told Hu Yuqing, he discovered that Liu Chao had 60 hands. The moves used in the final game are all the same as those of the Go AI software "LeeleZero High Edition".
The chess moves are almost the same as AI
Other players found Liu Chao’s most puzzling place was that he always put his mobile phone in his clothing and turned the camera lens outward. He held black with his left hand, played white with his right hand, and pressed the clock (calculator The time of the game clock does not interfere with the chessboard. Some netizens suspect that he is using the mobile phone for videoconferencing, the other end uses AI to play for him, and then uses AI's board game to conceal the headset. Transmitted to Liu Chao.
Hu Yuqing did not immediately lodge a complaint. However, some staff members noticed that netizens questioned Liu Chao's use of smart phones. Therefore, the staff advised Liu Chao to put away his mobile phone. However, because the game cannot search or check the mobile phone contents like law enforcement officers, there is no substantial evidence. In the case of his cheating, he did not cancel Liu Chao's eligibility.
Liu Chao continued to play without a mobile phone, but later left the venue without authorization. The tournament announced that he had lost the game due to the inability to contact the player. Some netizens said that he took every move without a mobile phone. The time spent is longer than before. On the other hand, the match degree of chess moves with LeeleZero AI artificial intelligence software has dropped significantly.
Cheating suspects call mobile phone pockets a habit
Liu Chao argued that he has made a lot of research on all kinds of Go AI, so it's not surprising that the game is similar to AI. It is his usual practice to put his mobile phone in the pocket because the two trousers bags are filled with mobile power and sundries. He finally had to leave the arena because he saw too many people on the network talking about him before the start. There were too many people watching and saying, "I myself suffer from depression." His own psychological impact, saying that he won is not lost or not, and finally decided to give up the game, and throw away the books, publications, and will not be involved in the future.

Afterwards, the media interviewed Hu Yuqing and asked why he did not immediately complain. Hu said himself. It was indeed a loss, and the doubts were discovered by friends and netizens. It was too difficult for the referee to collect evidence in a short time. Therefore, he did not take the initiative to lodge a complaint. He made a speech after the game, but he hoped that the incident would improve the Go game in the AI era. rule.
AI makers indicate high coincidence, high chance of cheat
There are media interviews with LeeleZero producers. Even if there is a lot of research on AI games, the possibility that the game's final coincidence with the AI is so high is minimal. Team representatives said that they know that the players have been suspected of using the games in colleges and universities in the province. In the case of AI, Liu Chao had a significant advantage at the time and was eventually defeated because of a timeout. It is most likely due to a problem in the network transmission process. Since AI software is open source, users are free to download and use, so developers cannot Detect anyone's record of use.
Chang Hao, vice chairman of the China Go Association, said that amateur players do not make much sense to cheat. From a professional point of view, due to the attraction of prizes and fame, they need very standardized measures. After the appearance of AI last year, the game has made some changes. , For example, it is not possible to close at noon, cancel the online qualifiers with high chance of cheating, etc.
