On October 21, the second day of the Samsung Cup Round of 32, "Eight Champions" Ko Jie Prancing Horse competed against Kim Ji-seok, who ranked fourth in the South Korean rankings.

This is Ke Jie's first world war since last year's LG Cup loss to South Korea's Shin Min and falling into a downturn. Prior to this, Ke Jie's state in the league and domestic competitions has rebounded, and Chinese chess fans still pin their hopes of blocking Shen Zhenchen on him, and can only pin on him.
Because of the help of AI winning rate, the current Go game can make us who are blind to Go and also enjoy the game. In this game, the two sides have ups and downs, wrong in and out.
The first turn came in the 109th hand, where Kim Ji-seok turned a blind eye to a 92.8% winning hand and basically chose the 49.7% winning point without thinking. Startled Chinese chess fans in a cold sweat.
In the subsequent matches, both sides parted ways with the AI, and the winning rate was like a swing, swinging up and down, but it was basically indistinguishable.
Judging from the change in the winning percentage, it feels that the 172nd hand is in the chess all the way, and there is a problem. The winning percentage was still in the lead, and from this hand on, the black chess piece never found the opportunity to turn over. In the end, Ke Jie lost 0.5 eyes to Kim Ji-seok and encountered a round of the Samsung Cup.
In the past year or so, the eight-crowned ke jie has walked downhill and drunk cold water to plug his teeth. After being eliminated in the first round of this year's Samsung Cup, it snuffed out all the expectations of all Go fans for Ke Jie to reinvigorate and challenge Shin Zhenchen. Although I don't know what the future will be, at least for a while, Ke Jie has fallen off the altar.
The root of this lies in artificial intelligence, artificial intelligence made by Americans who do not understand Go at all.
After figuring out the root cause of this, many of us may no longer doubt that Ke Jie's era is likely to end here. Because, the world of Go in the AI era has changed the world compared with the past.
In the eyes of chess fans, after Ke Jie was eliminated on October 21, the Samsung Cup game was almost over. It can basically be announced that Shin Zhenchen will lift this year's Samsung Cup.
Even harsher than that is, it can also be announced that the world of Go has changed. Since then, it has become a situation in which Shen Zhenchen is alone.
This situation is a major change in the Go world since Lee Chang-ho in 16 years. To say that everyone is not convinced, it can basically be asserted that the Shen Zhenchen in the era of artificial intelligence is stronger than Li Changhao 16 years ago, and there is no opponent. The reason is simple, it is Shin Jin-hyun who broke Lee Chang-ho's winning percentage record.
Since 2013, Chinese Go has experienced 7 years of spring, and today it is winter.
Little geniuses under the age of 13, the hope of defeating Shen Zhenchen is pinned on you.
