As the name suggests, "one son solves the double sign" is to solve the problem of the introduction of two pieces of chess with one son. "One son solves the double sign" rarely appears in the actual battle of Go. The earliest historical record of this chess shape appears in the Song Dynasty Li Yimin's "Forgetting Worries and Qingle Collection", and the protagonist of the story is the Tang Dynasty national hand Wang Jisheng. Also in the Tang Dynasty, the national hand Gu Shiyan greeted the visiting Japanese prince and won with a "one son to solve the double march".
Tang Sulu's "Duyang Miscellaneous Compilation" Yun:
In the middle of the great middle school, the son of the King of Japan came to the dynasty and offered treasure instrument music. There are hundreds of plays and delicacies to be ceremonial. The prince is good at Go, and the shangshu gushi is waiting for the edict as an opponent. The prince is out of the jade game, cold and warm jade chess pieces. Yun: 'Thirty thousand miles east of the country, there is Jizhen Island, and on the island there is the Ningxia Terrace, and there is a hand-talking pond on the platform. The jade chess pieces in the pool are not separated by the system, natural black and white, warm in winter and cold in summer, so it is called cold and warm jade. It is also produced such as catalpa jade, which is like catalpa wood, and is polished as a chess game, which is smooth and can be learned. ’
and the master's words and opponents, to thirty-three, the victory or defeat is undecided. The master is afraid of insulting the king's order, and if he contemplates with his hands and dares to drop his finger, it is said that the town of the god's head is to solve the two marches. The prince narrowed his eyes and shrunken his arms, already overwhelmed. Gu Shiyan zhen god head, and now the good deeds still have Gu Shiyan thirty-three town god head map.
In 1996, In the 20th Chess Holy War in Japan, Zhao Zhixun defeated Kobayashi Jue in the black middle game; in the 23rd NEC Cup Zhao Shanjin won the white half set in the smoke game of Yanagi in the 2003, there was a "one-son solution and double sign".
However, the most famous modern "one son solution double sign" appeared in the game of a generation of Go legend Lee Chang-ho.
In 2001, Lee Chang-ho was at his peak, he defeated China's Chang Hao in February to win the fourth Ying's Cup championship, achieving the World Chess Grand Slam; in May, in the LG World Chess Championship, in a 0:2 backward situation, he won three consecutive sets, and finally reversed the undefeated teenager Li Sedol of Bird Island 3:2. Challenged the previous champion Choi Myung-hoon at the LG Essential Oil Cup in South Korea in September.
Born in 1975, Choi Myung-hoon entered the 2nd LG Cup World Chess Championship Final 4 in 1998, won the third place in the first Chunlan Cup in 1999, and won the runner-up of the 14th Fujitsu Cup in 2001.
Lee Chang-ho's "one son to solve the double sign" of the ancient strange move appeared in the third set of the two sides.
In this game, Lee Chang-ho is black, black 9 sharp punch, and the chess is very active. A change from Lee Chang-ho's previous style of playing the benguet faction of laying floor officials to win victories.
After Bai 18 made up the game, Bai 22 scored deeply, which was to belittle Lee Chang-ho's strength.
Black 23 spire, white 24 fly, excessive suspicion, by the black 25, 27 hands rushed off, white 30 make-up time, black 31 broken is a good chess, white chess accident is somewhat difficult to do.
If White 1 catches, Black 2 is very happy to eat first, and by the way, destroy the eye position under the white chess, and the white chess piece is absolutely unacceptable.
In actual combat, the white chess piece did not come up with too good a response, and to 35 long, the black chess piece was very thick. Bai Qi's 36 leaned and 38 cut off, but he did not expect that Lee Chang-ho's 39th hand was actually standing in the second road, which was the strongest counterattack against Choi Myung-hoon's disregard for his own strength. At this moment, neither side can give in to the momentum. Cui Mingxun was not ready to admit his concessions, and Bai 40 fought back angrily. By White 42, the two sides had entered a one-way street with no way back for each other.
White chess 62 to 70, AB two points of convergence, AB signs as long as one of them, black chess will collapse. It is estimated that at this time, Choi Myung-hoon believes that he is already victorious in sight, and perhaps he thinks that in terms of strength, Lee Chang-ho is still slightly inferior after all.
However, Li Changhao's clever hand of eternity, the black 71 town god head, a son to solve the double sign! White chess collapsed in an instant.
Marching to the black 81 hand, the white chess belly dragon was killed, and Choi Myung-hoon conceded defeat.
It is conceivable that when Li Changhao walked the 39th position, he must have foreseen the 71-handed one-son solution double sign, and the stone Buddha calculated the far-reaching road, just like playing with the opponent on the palm of the hand, making all the opponents despair!
Choi Myung-hoon, who lost the game, seemed to have suffered a great blow to his confidence, and since then he has been devastated and gradually faded out of the ranks of South Korea's first-line chess players.
The accurate computing power shown by Lee Chang-ho in this game also greatly shocked the world chess world, completely destroyed the confidence of Chinese and Japanese chess players, and thus ascended to the altar. It was not until the 10th Three Star Cup in 2005, when the Divine Pig Heavenly Descent of The Roche River magically pulled Lee Chang-ho, and Lee Chang-ho's reign of terror came to an end.
