There is a saying in the amateur Go world: because Lee Chang-ho is Cao Xuan-hyun's apprentice, Lee Chang-ho felt embarrassed after winning the title of master, so he let go of chess in many games.
Let chess? How many games are there? It seems that this is still biased in the understanding of the professional world.
Let's take stock of the confrontation between Lee Chang-ho and master Cho Hyun Hyun, and only look at the match where Cho Hyun Hyun challenges Lee Chang-ho.
At that time, the competitions in the Korean chess world probably included celebrity battles, national hand battles, throne battles, overlord battles, highest position battles, KBS chess king battles, and strongest battles.
Time is limited, space is limited, and today we only take stock of the national hand war
In the national hand war, the master and apprentice meet in a narrow way
In 1990, at the 33rd National Hand Battle Challenge in South Korea, the opponent of Cho Hwan-hyun was not Seo Bong-so, but his own apprentice Lee Chang-ho. At that time, Lee Chang-ho was slightly immature, and lost 1:3 to Cao Xuanxuan.
In 1991, in the 34th National Hand Battle, Lee Chang-ho, as a challenger, defeated Cho Hyun Hyun 3:0.
In 1992, in the 35th National Hand Battle, Cho Hyun Hyun went all the way out and challenged his apprentice Lee Chang-ho for the first time as a challenger in the National Hand War. How incredible is it for a master to challenge an apprentice? However, in the world of victory and defeat, where are so many masters and apprentices? At that time, the Japanese Go was as strong as a cloud, and the Sixth Super Did not accept apprentices at its peak, and even if it did, the apprentices might not be able to challenge the master in the official competition. As for the Chinese Go at that time, only Nie Weiping, Ma Xiaochun and Qian Yuping were the strongest. But these three people did not accept apprentices at that time, so it is impossible to "master challenge apprentices" in official competitions. Therefore, it became "inconceivable" for Cho to challenge Lee Chang-ho.
Fortunately, in the 35th National Hand Battle, Cho Won-hyun defeated Lee Chang-ho 3:2 and successfully challenged his apprentice for the first time.
In 1993, Lee Chang-ho challenged his masters Cho Hwan-hyun and Cho Hyun-hyun to defend his title 3:1.
But the master-apprentice war of the victorious and defeated worlds has only just begun, and the nightmare of Cao Xuanxuan's hand war has just begun.
By 1994, Lee Chang-ho had become the strongest in the world, and in every way, Cho was slightly inferior.
This year, challenger Lee Chang-ho again kept a clean sheet for Cho Hyun Hyun 3:0.
Defended at 3:2 in 1995
Defended at 3:1 in 1996
Defended at 3:2 in 1997
In 1998, Heo Bong-so, who did not appear in the National Hand War Challenge Bureau, replaced Cho Hyun-hyun in challenging Lee Chang-ho, but still lost 3:1.
In 1999, the year of the final of the first Chunlan Cup, the veteran and strong Cho Hyun Hyun defeated Lee Chang-ho 3:0 to win the national championship again.
In 2000, the challenger was the strongest female chess player ever: Rui Naiwei Jiudan.
To borrow a phrase from the Go author "Moon Full of Great Rivers": If someone says that Choi Jing defeated Park Tinghuan in the Korean chess battle, Fan Qi defeated Shin Jin-chan in the final to win the championship, or Yu Zhiying defeated Yang Dingxin in the Chinese chess battle, and Fan Qi defeated Ke Jie in the final to win the championship, I am afraid that no one believes that this possibility will happen, and 1% of the possibilities will not believe it.
So far, Choi Jing has not won consecutively against Park Tinghuan Shin Shin Zhenchen, and Yu Zhiying has not won consecutively against Yang Dingxin Ke Jie, but Rui Naiwei has done it. She defeated Lee Chang-ho in the challenger decision game, and she didn't know why the wuban chess challenge became a three-game chess game this time and then a five-game chess game after this year. In short, Rui Naiwei defeated Cao Xuanxuan 2:1, and after Rui Naiwei won the national championship, he not only shocked the world chess world. It also deeply inspired Korean women's Go.
In 2001, Cho Won Hyun successfully challenged 3:0, and it is said that Rui Naiwei has never won again.
In 2002, Lee Chang-ho unsurprisingly pulled Cho off the horse with a total score of 3:1. Since then, Cao Xuanxuan has "disappeared" in the challenge tournament, and Cao Xuanxuan, who has been in the Korean chess world for more than 20 years, has slowly "disappeared" in the impact of younger chess players and in major title competitions.
Summary: Since he successfully won the national championship in 1977, Cho has almost always ruled the national championship like Taishan. After the rise of Lee Chang-ho, Cho Hyun Hyun's chances of winning the National Hand Championship are becoming less and less, and the two have challenged a total of ten times in the National Hand Championship Challenge, and Lee Chang-ho has successfully challenged three times and defended the title for three consecutive times. Cho challenged Lee Chang-ho seven times, successfully challenged two times, and defended his title twice.
If Cao Xuanxuan's happiest thing in the chess world is to win the first Ying's Cup, then the Lee Chang-ho he cultivated should be the second thing he is happiest in the chess world. If the most painful thing for Cho Hyun-hyun is not to go to Japan to win the Championship of Ben in- Ande, then the second thing he is most painful about is watching his titles being taken away by his apprentice Lee Chang-ho one by one.
At the same time as suffering, how can this not be a joy? Isn't the reward of the Go world the apprentice defeating the teacher? And this kind of pain, whether it is joy or joy, it is the truest side of the world of victory and defeat.
