Double insurance refers to double guarantee and double protection, and people often use double insurance to describe the control of the stable development of future things. In the world chess world, the word double insurance once appeared. The earliest double insurance appeared in the first Sino-Japanese Go Tournament in the 1980s, when the Japanese side sent two super first-class double insurances, Koichi Kobayashi and Masao Kato. Of course, that double insurance unexpectedly failed under the heroic performance of Nie Weiping Qisheng in China.
But the most well-known double insurance of Go is the era of double insurance composed of South Korean chess players Lee Chang-ho and Cho Hwan-hyun. Cao Xuanxuan is the recognized world first among the post-50s chess players, and Lee Chang-ho is the recognized world first among the post-70s chess players. In the 1990s, the world chess world entered the three-country Go tournament period, and the Korean go national team composed of Cho Hwan-hyun and Lee Chang-ho swept through China-Japan Go, monopolizing all 5 Zhenlu Cup Three Kingdoms Go Tournament team champions and the first SBS Three Kingdoms Go Tournament champion. He also won several individual world championship titles.
When Chinese and Japanese Go masters talk about Cao Li's master and apprentice, they have a headache. Because it is difficult or impossible to surpass Cao Li's master and apprentice. If Cho Hyun Hyun loses his hand, lee chang-ho will sit in the seat; if Lee Chang-ho is accidentally lost, there will be the old and strong Cho Hyun hyun in the seat. It is extremely difficult or impossible to win both of them at the World Series. It is no exaggeration to say that Cao Li created and suppressed an era. Cao Li has won a total of 26 world championships, 6 three-country Go tournament championships, and 9 Nongshim Cup team championships. Such achievements are unprecedented or even unprecedented.
Later, Lee Chang-ho and Lee Sedol also formed a short-lived double insurance era, but due to Lee Sedol's poor performance in the Nongshim Cup, the contradiction with the Korean Chess Association always existed. The pair look dazzling, but the results are far less dazzling than those of Cho and Lee Chang-ho.
Now Korean Go once again has double insurance, that is, the old and strong Park Tinghuan and the sun in the sky Shin Jin-chan composed of double insurance.
In the semi-finals of the 26th Samsung Cup on October 27, Park Tinghuan defeated Chinese chess player Zhao Chenyu to advance to the final. In the previous quarter-finals, Park Tinghuan stubbornly reversed the Chinese chess player Lian Xiao into the final four in a desperate situation with a winning rate of only 3%. Park Ting-hwan's tenacity is touching. Let people vaguely see the figure of the evergreen tree that Cao Xuanxuan exceeded the physiological limits of age.
In another semi-final of the 26th Samsung Cup on October 28, Shin Jin-chan defeated Chinese player Yang Dingxin to reach the final, so that Shin Jin-chan and Park Tinghuan won the first and second places in this Samsung Cup competition. Shin also achieved an impressive record of 16 consecutive wins in the World Series. Shen Zhenchen has won 16 consecutive world series since the 2020 Samsung Cup final 0:2 to Ke Jie, including the Ying Cup 2:0 Zhao Chenyu; the Chunlan Cup wins Fan Tingyu and Lian Xiao, 2:0 Tang Weixing wins the championship; the Nongshim Cup wins 5 consecutive wins; this year's LG Cup enters the quarterfinals; and the Samsung Cup wins four consecutive wins to reach the final.
In the final stage of the 22nd Nongshim Ramen Cup, Shen Zhenchen defeated Japan's Yuta Iizo, Yili Liao and China's Tang Weixing, Yang Dingxin and Ke Jie, five super-first-class chess players, winning five consecutive victories in a wave of five consecutive victories, and winning the Nongshim Cup as a vice marshal, which was extremely impressive. In the first stage of the 23rd Nongshim Ramen Cup, Park Tinghuan unexpectedly appeared early as a South Korean vice pioneer, and unsurprisingly won the Japanese power chess player Heo Jiayuan. Under the impact of this pair of Korean insurance, Korean Go has taken the lead in this year's Samsung Cup and Nongshim Ramen Cup Trilateral Team Competition.
Fortunately, China still has Ke Jie, otherwise we don't know how many years this pair of Korean double insurance will suppress Chinese Go.
But Chinese Go can no longer sleep on the merit book, Ke Jie is 24 years old this year, and one day she will helplessly bid farewell to the peak of her career. At that time, what should Chinese Go do? We still don't see a rookie who can succeed Ke Jie.
