The second game of the LG Cup final continued at the Korean Chess Institute, with Ke Jie facing off against Byun Sang-il. Ke Jie was judged to have lost, sparking significant controversy. The incident began when Ke Jie failed to place his piece in the chess cover after lifting it, resulting in a two-point penalty from the referee. The game progressed to the 80th move, where Ke Jie lifted another piece. South Korean player Byun Sang-il signaled to the referee, pointing out that Ke Jie had committed another violation. The South Korean side announced that Ke Jie's second lifting of a piece was in violation of the rules, and due to accumulating two violations, he was directly judged to have lost. This is also the first time in the history of the Go world championship finals that a loss has occurred due to a rule violation. Many netizens expressed their dissatisfaction, and Yu Bin, the head coach of the Chinese national Go team, strongly protested but ultimately agreed. A suspected official account of the Chinese Go Association on a certain platform's live broadcast room stated: "Rules are rules, they weren't set today." After the match, Byun Sang-il's moment of reporting Ke Jie was turned into a meme, which can be considered an unconventional divine move. Byun Sang-il's expression appears somewhat aggrieved, but in reality, he is doing the most ungracious thing. A peak confrontation match did not end because one was superior in skill, but rather due to reporting and unfamiliarity with the rules, which is indeed regrettable. Of course,…

On January 20th, in the first game of the LG Cup final, Ke Jie took the lead by winning by 2.5 points with black pieces against Byeon Sang-il. This game was a full-scale chaotic battle, played with tension and excitement, leaving the spectators calling it thrilling. However, it's not entirely clear how Ke Jie managed to win or where Byeon Sang-il made his mistakes, even with AI at hand. To explore this further, I have compiled comments from commentators at Yike, Yehu, and Xing Xiaomu to try to understand the game better. Yike's commentary mainly represents the AI's perspective, focusing on which moves deviated from AI recommendations and which caused a drop in win rates. There were significant mistakes such as White's move 142, dropping the win rate from 77% to 33%; Black's move 183, dropping the win rate from 91% to 62%; White's move 196, dropping the win rate from 51% to 16%; Black's move 201, dropping the win rate from 89% to 55%; and White's move 218, dropping the win rate from 59% to 0. Yehu's commentary identified three key points: the first being Byeon Sang-il's move 142, a major mistake that AI estimated to decrease the win rate by 40%-60%. Yehu believes that this move trapped all the white pieces, whereas if a different strategy had been chosen, the white pieces could have survived. The second key point is Ke Jie's move 175, where he made an incorrect choice. Yehu suggests that if Ke Jie had chosen to eliminate the upper left corner, the situation would have…
