On the evening of March 28, 2024, I watched the first game of online chess against South Korea's Han Yujin (now known as Han Youzhen) on Douyin. It is said that Han Yujin is the champion of the Korean rookie king competition, and he is only 19 years old this year, which shows that he is also a new force in the Korean Go world. Han Yujin proposed that he play blitz chess in black for 15 seconds, and Wang Haoyang happily faced it.
At the beginning of this game of chess, Wang Haoyang did not explain much, it can be seen that the situation is not optimistic, after the chess game is over, Wang Haoyang summarized his three feelings (summarized by the author):
First, after the three-corner pattern is completed, white is quite stressed, and the AI runs to show that white is not good.
The second is that the black chess in the lower right corner is unfavorable, and he even sends another one, and then pulls a piece. In this way, the evasion is generally a loss, but the conclusion given by the AI is that the evasion is not a loss. This gives white the illusion of a game, thinking that black has lost money, but it is not.
The third is that in the prelude stage of the fixed formula in the upper left corner, black makes white pluck the flowers, and the result is that black does not lose, which is too speechless.
In the end, Wang Haoyang sighed that the Korean chess players have really studied the prologue game in depth, is this game a flying knife? This game is worth looking into again.
I tried to run a little bit with KataGo (Go AI), and tried to learn about AI moves and ideas, and now I will share it with you.
Figure 1
Figure 1: This is the graph of the winning rate of both sides given by Yicheng's AI, as Wang Haoyang said, after the three formulas are completed, Black's winning rate has "secretly" surpassed that of white. At this time, white may still think that white is not bad because of the escape sign on the right side of the black piece and the white piece on the top left. As you can see from the position indicated by the arrows in the diagram, black has been increasing since then.
Figure II
Figure 2: Using KataGo analysis, the next black piece to escape the sign, although it is not the first choice recommended by the AI, is still one of the recommended good points, which is the fourth choice. Zhengzi can also escape sometimes, isn't this subversive of your perception of Go?
Figure III
Figure 3: For the black piece to escape the sign, the AI's first choice is the small tip, and the specific move is in the small image in the lower right corner of the picture. Black has a response in the upper left, and it should be natural for white to choose the flail, and this point is the AI's six choices. Wang Haoyang felt that the white chess on the lower side had already eaten the black piece, and the black chess had sent another one, and he felt that the black chess was a loss.
Figure IV
Figure 4: Black 35 escapes one, and then plays a live corner in the lower right corner, AI recommends that white 40 must eat these two sons, and the actual combat also goes like this. During the review, Wang Haoyang posed for the AI's recommendation change (small picture in the lower right corner), Wang Haoyang said that this black chess is really empty, and he feels uncertain about how to manage the middle abdomen of white chess.
About this black 35 escape, can we understand it like this, this is actually a flexible application of the abandoned son to abandon the two Tesuji on the side. After all, white 36 and 40 have to play two moves, so there is also the use of the outside point, which shows that it is not a loss to escape a black piece. What do you think, chess friends?
Figure V
Figure 5: Black 41 hanging corners, below to black 45 pallets, there are very few points. One choice is to retreat white, the second is to choose the upper right corner of the hand to pull first, the third is to choose the upper left three or three to pull, and then the actual battle is to break the levy and eat a black piece. Let's take a look at them one by one and feel which one should be chosen.
Figure VI
Figure 6: This is a selection given by the AI in the upper left corner, single return.
Figure VII
Figure 7: This is the second choice given by the AI in the upper left corner, first pull one in the upper right corner, and then pull three or three in the upper left corner. Personally, I think I would choose this diagram, which is more intuitive.
Figure 8
Figure 8: This is the third choice given by the AI.
Judging from the chess shape, these three options do not seem to be much different, and the goal is how to manage the midbelly.
Figure IX
Figure 9: In the actual battle, the white chess sign is drawn and the black one is removed, and the black chess has two small flies on the left, which is also an AI choice (the teacher who originally remembered said that it is not good to keep the corner like this, and there is still a bit of a corner on the corner.) Hehe, the AI says that's good!). How do you enclose the middle? AI told you, the position of the red △. Let's develop a chess sense!
Figure X
Figure 10: This is the actual battle in the future, both sides are one and two choices, and in the case of one step in 15 seconds, it is really not easy to choose one or two choices for AI. The next step is not to say whether it is a mistake of white chess, and the white chess break is not in the AI's choice. When the surrounding area is full of white chess, shouldn't it be broken? This is the fixed thinking of human beings, and to encircle the space is to encircle the right side and see how much the right side can encircle.
FIGURE XI
Figure 11: At this time, the AI provides us with another idea, who said that we must encircle the right, and white chess is changed to the left, so that the power of pulling flowers can be revealed, so that the winning rate of white chess is 53.4%.
FIGURE XII
Figure 12: White breaks 60, and Black's win rate instantly reaches 75.3%. Who would have thought that White's strategy would be to rely on the strong momentum on the right to empty on the left?
