Based on the Sino-Japanese Young Chess Players Tournament in the 1980s,
Wang Yi (black) against Ishida Tokuji (white) chess. Under the black wheel,
By the 15th rush, Bai Qi actually conceded defeat.
In fact, the result of the killing is white and black.
The reason for the miscalculation of white chess, white 1 is tight here, is actually miscalculated.
Still a chess game from the 80s, Mimura Tomoho (black) in the early stages versus Li Liang (white). This situation, round black chess,
After the white 2 and 4, the black chess suddenly conceded defeat, in fact, the situation black chess was slightly better. Bai Qi's fighting spirit is completely lost, and he blindly imitates the demeanor of the master who is not dead and fighting, so he concedes defeat.
On May 22, 1985, in the ninth round of the first Sino-Japanese Go Tournament, Qian Yuping (Seven Dan) blacked against Koichi Kobayashi.
This year Qian Yuping was 19 years old, Kobayashi Koichi was 33 years old, this was the situation in the final game when Qian Yuping signaled to concede, Qian Yuping felt that his horn was dead, there must be no play, plus a long time reading seconds, admitting defeat is also a relief.
In the research room, Shao Zhenzhong and Nie Weiping have found that if the black chess continues, a complex confrontation will be formed, and the 25 sons of the white chess triangle will not be guaranteed, so it is the situation of the victory of the black chess, which is the origin of the winning chess conceding defeat.
Tokyo, June 3, 2010, 22nd Asian Television Quick Chess Tournament Finals Kong Jie (White) beat Satoshi Yuki (Black) in 176 hands.
Actual score 1-11 hands (that is, 166-176 hands), just at this time, the black chess suddenly conceded defeat, which made people confused.
It is estimated that it is white 3 (168 hands), and the mood of black is greatly damaged.
After the simulation: White 2, 4 is just a live chess piece. Satoshi Yuki probably found the white triangle difficult to clean up, so he conceded defeat in order to seek relief.
Reference figure: According to Nie Weiping and several professional chess players jointly studied, in fact, the upper left corner of the black chess piece also has a winning move, the black chess piece is in 1 position, the white chess piece if the 2 bits are pulled, the black chess piece is 3 tigers, because the black chess is thick overall, the white chess does not dare to eat the A position, otherwise it is doomed to be a disaster. If the white chess piece is eaten in the 4th place, the 5th place of the black chess piece cannot be resisted by the white chess piece (it is advantageous to rob the black chess piece).
Reference figure: So when the black chess piece is pulled by 1 position, the white chess piece can only be endured in the 2 places, and the following black chess piece can be done first, and then the two sides continue to end, the best order is probably 9-28 hands, so the black chess advantage.
Jie Chengcong confessed that there was some injustice, and Nie Weiping even believed that this was the biggest unjust case of this century. However, according to the opponent Kong Jie, after he worked on the central white chess, Yucheng Satoshi was in a bad mood and had no intention of fighting.
Speaking of which, it is time to point out the question: they have conceded defeat, where will the victory come from? The shortcut to increasing the strength of Go is actually in research, which is a positive way to pursue the progress of chess, but the chess players in the game room are under pressure, but also urged by the reading of the second sound, and they cannot put forward reference charts, so the winning chess mentioned here is only a chance to win, as for whether to go out, the researchers who say win chess can not care.
The big win of the replay and the win of the replay are all the results of the legend. The secret of winning and conceding defeat is roughly like this.
There are only three reasons for conceding defeat in the game of Go: 1 Ishida Toshiji's miscalculation, 2 Mimura Tomoho's pursuit of demeanor, and 3 Qian Yuping or Satoshi Yuki's fighting spirit.
After carefully reading the four games of chess, do you still say that they lost unjustly?
