Focus on liao yuanhe vs. Zhao Chenyu
On April 10, the second round of the 2021 17th Advocate Chess Cup Rematch was held at the Wuxi Zhongwei Blue Ocean Royal Hotel. From the preliminary round to the semi-finals, the schedule has entered the 6th day, and the Spring Festival Competition in which Chinese Go regained lost ground since the epidemic last year will successfully conclude the preliminary and rematch stages.
The second round of the rematch
In the first round of the preliminary round on April 5, the first stage group of last year's fixed stage appeared on the field, but only Wang Chuxuan walked to the third round of the preliminary round. Among the chess players who participated in the first round of the preliminary round, only Han Enyi played to the fourth round of the preliminary round, but failed to reach the rematch on April 9.
The chess players who entered the first round of the rematch were basically from Wei A and B, among which Ma Guangzi, who was born in Wei B (who did not play Wei B last year), defeated Wang Xinghao in the first round of the preliminary round to enter the second round of the rematch, and his opponent was Chen Xian.
The Champion Chess Cup has adopted the Rules of Ying from the resumption of the tournament, and there have been various interesting scenes on the first day of the game around the rules of the penalty point system.
Wang Yao on the first day of the rematch
Rong Yi's match against Wang Yao, Wang Yao still had more than 10 minutes left, and his judgment of the situation fell into extreme pessimism. When Rong Yi landed the 208th hand, Wang Yao's winning rate of black chess was still around 43%, but Wang Yao pushed the orange to admit defeat. At this time, Rong Yi's time was still more than 1 hour and 40 minutes left, and Wang Yao may have become pessimistic about the situation after the penalty point.
In fact, under the Rules of Ying, at present, artificial intelligence cannot give the starting point an accurate winning rate judgment after that. The package dry competition of the Ying rules will produce the problem of "losing more in order not to punish the officials".
Gu Lingyi in the first round of the rematch
Ma Yichao's match against Gu Lingyi, Ma Yichao has won the official closing stage, but it takes less than 1 minute left, and he will soon fall into a penalty point. At this time, Gu Lingyi still had more than 40 minutes left, and after Ma Yichao fell, Gu Lingyi did not shoot the game clock. After finishing the official, Ma Yichao won by 1 point, and if the penalty point was instead lost 1 point.
Around the Ying rules, the reporter interviewed Yang Shuo, head of the professional competition department of the Chinese Weiqi Association. Yang Shuo is responsible for the competition work of this year's Qiqi Cup.
Referee Jin Shan Chuduan and Yang Shuo, head of the professional competition department of the China Go Association, discuss the Ying rules
Yang Shuo said: "In the first Ying's Cup in 1988, the penalty point system was not adopted, and the game was still reading seconds. However, the first Ying Cup adopted a special double-active rule, when the pieces are adjacent to the black and white, the two sides are divided equally, if the black chess two sons swing one, the black chess will take two-thirds, and the white chess piece will take one-third. Therefore, in the first competition, Cho Kao-hyun vs Kobayashi Koichi had a black victory of 1 and 5/6 points.
Later, I felt that this rule was too troublesome, so I did not use it. At the beginning of the second session in 1992, the penalty point system appeared. At that time, it took three and a half hours for one party, and the time spent to buy back the penalty point was one-sixth of the time spent 35 minutes, and the penalty point could be bought three times.
At that time, the extreme of a game of chess was 7 hours and 210 minutes, and Chang Hao jiudan still remembers that the game he won in 2005 was played until 7 pm.
In the second round of the rematch, Liao Yuanhe toured the field
Later, the late Mr. Ying Minghao thought that the number of eyes was too cheap when frequent penalty points were bought, and in 2015 it was changed to three hours per party, and in 2017, it was changed to two penalty points, 20 minutes each time, and the game was completed within seven and a half hours. The new rules were adopted from the time of the Qiqi Cup and are still in use today.
On the first day of the rematch, Gu Lingyi did not press the clock, so that the opponent lost 1 point after finishing the official, which reflected the chess style bone. This scene also appeared on the Ying's cup. In 2012, Liu Xing lost 1 point in the match against Zhao Zhixun, and Zhao Zhixun only had a few tens of seconds left, and the chessboard was playing a single film robbery, and Liu Xing directly conceded defeat. ”
Ma Photon in the second round of the rematch
Finally, Yang Shuo said: "The principle of the Ying Cup is to refuse to rely on reading seconds without restriction, and then to refuse to play chess. Therefore, the Ying Cup adopts a special rule prohibiting the repetition of the same type of three robberies, etc., but it is interesting that the Ying Cup rules have not been produced so far, whether it is the World Collegiate Competition, the Chen Yi Cup, the Advocate Chess Cup, and the Ying Cup, there has never been a game that requires the use of special rules. The Ying Changqi Go Foundation offered a reward for a match with special rules, but no one has received the prize so far.
The Ying rules allow for 'suicide', and if this scene appears, it is a big test for the current live broadcast software, and it is fortunate that it has not appeared. ”
