Whether it is a professional master or an ordinary enthusiast, they must have encountered the situation that the opponent struggled to support in a desperate situation and never conceded defeat, was there an idea of "the opponent has no chess pieces" at that time?
But chess is under people, not AI, as long as it is under people, even if it is 100 mesh ahead, there is still a possibility of last-minute error. Such mistakes have occurred to players such as Yoo Shi-hyun, Shuzo Awaji, and Park Ji-eun.
Actual Combat Figure 1, in February 2002, the 5th game of the 26th Chess Holy War in Japan, Wang Licheng's nine dan white against Liu Shi smoked seven dan. Before the endgame, White 2 ate six sunspots, and Black 3 did not pick up in 4 places! White 4 mention, chess reversal.

Practical figure 1
Actual combat figure two, in May 2000, the 4th Ying's Cup 2nd round, the black Ma Xiaochun nine-dan defeat has been determined, but at the last moment Awaji Xiu Sanbai 2 tight breath, black 3 to eat, everything is resting, Ma Xiaochun escaped from death.
Practical figure 2
Actual combat figure three, on April 4, 2014, South Korea's 19th Women's Stream National Hand Battle Sanban Chess Final Game, Park Ji-eun Nine Dan Black vs. Kim Cai Young's first section, before the final game Black 1 sticks to himself tightly, the white chess piece will be the upper right sunspot all lifted, instantly overturned.
Practical figure 3
It can be seen that no matter how much it is backward, as long as it does not admit defeat, there will be a possibility of reversal. Although the probability of such a is extremely low, as long as there is such a possibility, it is possible to lose a chance to turn the tables.
But things are not so simple, Go is not just a winner or loser. In the game, if the situation lags too far behind and insists on resisting, it will most likely lead to contempt or even contempt. In an online game, Liu Changhe Jiudan was very disgusted with the behavior of Chinese chess players who still did not admit defeat after the defeat had been determined, he said: "White chess insists on no meaning, the difference is 30 mesh, there is no place to win or lose, Chinese chess players have many advantages, very persistent, excellent, but the feeling to me is not to vote." I've run into a lot... I am afraid that Chinese chess players have received such an education when they learn chess, that is, those who can test the opponent have finished the test, and those who can test the opponent have gone through before they can throw. ”
Liu Changhe nine paragraphs
At that time, I was quite surprised to say this to Yoo Chang-hyuk, because when it comes to tenacity, Korean chess players are far more than Chinese chess players. Chinese Go in the early years of the japanese Go, and Japanese Go is notoriously pay attention to the "Tao", not to mention the stubborn resistance in the situation of great defeat, that is, the chess shape is broken, and the slightest step of the thunder pool will cause the severe rebuke of the predecessors, and the younger generations have no chance to defend. Remember the slap of AEY's predecessor, Einan Sakata, or Sakada Eiko, a student of the Japanese Chess Academy, was immediately slapped by Yayon, the editor-in-chief of the "Chess Road" magazine at the time, because he said two more words during the review. In such an atmosphere, the younger chess players only have to listen to the senior chess players to talk about chess.
South Korea is located on the peninsula, for many years have survived in the cracks between the big powers, the external living environment is not easy, the Korean people have cultivated the character of stoic and tenacious factors, in the 1990s when the "Korean stream" in the Go industry rises, The Korean chess players killed and did not admit defeat the chess style made Chinese and Japanese chess players suffer a lot, and later the Chinese and Japanese chess circles called the "Korean stream" as an empirical school, that is, all victories and defeats are solved through actual combat, whether it is in line with the chess path, only in the second place.
In contrast, Chinese and Japanese Go had many elements that did not seek to understand, encountered every formula, every part of the "Korean stream" that was chased to the end, countless scenes of being overturned under the great excellent situation, and Chinese chess players experienced too many painful setbacks before gradually moving closer to the "Korean stream", and the chess style began to become sharp and tenacious.
Of course, there is also the strong background influence of the professionalization of Go, after the Chinese Go began to cultivate the dojo mode, the children who learned to play chess have faced cruel victories and defeats since childhood, and have practiced a more tenacious chess style than the "Korean stream". This is also the inevitable result of professionalization, and it is also the core fundamental of the later Chinese Go becoming a tiger, making Korean Go a wolf.
But in addition to winning and losing, Go also has artistic qualities. Unlike football, basketball, volleyball and other sports competitions that focus on participation and physical fitness, Go also has a kind of "tao" in support, if a painting is broken, it should be restarted, and if it is retained, it is a failure; a song that is out of tune should stop and start again, rather than continue. This is the requirement of art, which is very different from winning or losing.
Previous Japanese Go masters, such as Hero Otake and Masaki Takemiya, have warned the younger generations with the requirement of "not dirty chess scores", chess scores are to be passed on to future generations, obviously there is no chess place, you have to deceive the opponents to point in, take advantage of the opponent's time tension or do not pay attention, pick up leaks to win, such chess scores are certainly divided into victory and defeat, but from an artistic point of view, it is a "dirty" chess score.
In the 1995 Sino-Japanese Go Tournament, the hero of Otake Nine Dan defeated Liu Xiaoguang Nine Dan, that game Liu Xiaoguang tried to play in the opponent's empty space in the situation where the defeat was determined, and after the game, Ohtake Hero was furious and refused to review. In his opinion, "digging" into a place where there is no chess piece is "dirty" chess.

However, in today's Go has become a win-lose competition, as long as the victory or defeat is undecided, the chess game is still continuing, and any move is blameless, and this winning and losing attitude may be more in line with the modern competitive environment, not seeking the process, but seeking the result. I remember that there were chess fans on the Internet who declared that "I most appreciate the 'Mo Wang' Qiu Jun, and I will not give up at any time." "Perhaps, this is the real life, and art always has to go beyond life."
