In the Korean Go world, Cho Hoon-hyun is the third generation of kings, and in front of him are Cho Nam-chul and Kim Yin.
Choi Zhehan is a post-80s generation and Cao Xunxuan is a post-50s generation, so there is a gap of about 30 years between the two sides.
Although Choi Cheol-han was once known as Lee Chang-ho's nemesis, his light was in front of his contemporaries Lee Sedol, with two words: bleak and dull.
But none of the above detracts from the excitement of the two-man game.
Cho Hoon-hyun
Choi Zhehan's Go nickname is Viper, but he doesn't seem to like it.
Cho Hoon-hyun's nickname is very positive, the emperor of Go, and the praise of the Korean Go community reveals between the lines.
Reference picture 1: Choi Zhehan is white, Cho Xun Hyun is black, this is the moment when Choi Poison's 180th hand used a knife to slaughter Cao Xun Hyun's big dragon.
Choi Cheol-hsien
How did Choi do it?
Let's turn the clock back to September 13, 2004, which was the first Korean Champion of Champions Quarterfinals, and Choi Zhehan's display of the five fools ranked fifth among the five fools in the history of Go (Personal Collector's Edition).
Cui Zhehan recently eliminated China's Peng Quan 2:1 in the semi-finals of the 5th Yingshi Cup World Professional Go Championship, and entered the final of the Yingshi Cup for the second time.
Actual Combat Diagram 1: At this time, Cao Xunxuan's black chess will win as long as the dragon does not die.
Black 171 is the last defeat,
Refer to Figure 2: Black only needs to be in the top position, and A and B must get one of them, so that the white chess dragon can be strong.

Diagram 3: AI emphasizes that white is in a good position at the moment.
