1996 Semi-finalist of the 7th Toyo Securities Cup
Black: Zhao Zhixun
White: Lee Chang-ho
In 1996, Cho Ji-hoon defeated Kobayashi Kyaw, Yanagi Shifu, and Masaki Takemiya, once again winning the Grand Triple Crown and returning to the throne of the first person in Japan, but he broke the sand on the Toyo Securities Cup and lost again to Lee Chang-ho, and this game is one of the few famous games of "Stone Buddha" to win by force.
Figure 1(1-26)
Zhao Zhixun started with a high Chinese stream, obviously hoping to introduce the situation into the pattern of the battle, so as to avoid the official restraint of Lee Chang-ho, and the Black 7 Clip also implemented this intention.
The stereotype at the bottom right was a very popular change at that time, and even in today's day, it is roughly two points from the winning rate given by AI.
Figure 2(27-29)
When the black 27 points, the exchange between the white 28 pull and the black 29 is a loss of chess, because the original white chess corner is left with the white A and then B, black C, white D to do the means of slowing down the gas robbery, white 28 and black 29 after the exchange of this means no longer exists.
The reason why Lee Chang-ho wants to do this exchange is that he is ready to abandon the white triangle three sons, because once the white three sons are eaten, the exchange of white 28 and black 29 is obviously cheap in terms of eye number.
Figure 3 (30-34)
And Zhao Zhixun also saw through Lee Chang-ho's intentions, so when the white 30 paste, the black chess did not choose to eat the white triangle three sons, but chose the 33 jump out - since the white chess has done the exchange of 28 pulls and black 29 losses, then the white triangle three sons are not worth much, like chicken ribs.
At this time, looking back, I feel that the exchange of white circles and black circles is obviously a loss, and here the two sides are fighting, and the final result is that black chess has taken advantage of some advantages.
Lee Chang-ho seems to have some wishful thinking.
White 30 will be better if it takes the A position to fly, because the black chess will still go to the early 33rd place, then the white chess will fly 34, so the food is bigger.
Fig. 4(35-49)
Black 35 to 49, each side occupies a large field, and the chess situation seems to be leveling up.
But this apparent calm, just like the calm before the storm, under the seemingly undisturbed water, is actually a dark tide.
There is no fixed shape on the upper right of the black chess piece, and the weakness pulled out by the remaining A position is about to become the fuse of a big war.
From the point of view of the back of the game, the black chess piece should probably first go A position and exchange it with the white chess piece, and then return to the big game of 49.
Of course, this is not to say that the black chess pieces did not exchange this game is the defeat of the game, but in fact, the hidden dangers left by the black chess here are the causes of the failure of the black chess game.
Fig. 5 (50-76)
After leaving various borrowings on the top, the white 50 or below decisively pulled out from the 56th, and the stone Buddha was also made the "Angry King Kong".
Black 73 originally meant to be unwilling to pass through the C position, hoping to make Bai go first B black and then adjust C, that is, to seek a tone, but also a small cheap. However, this hand of chess induced the good player of the White 74, and the stone Buddha also performed extremely well in local contact battles.
With the white 74 hand chess, when the white 76 is mentioned again, the black triangle double backgammon tendon is announced to be killed, because at this time, if the black is sticky, the black chess cannot be blocked by the white C, as shown in the following figure:
Figure 6
At this time, you can find that the exchange between the white triangle and the black triangle is wonderful, after the black 7, the white A runs out, and the black chess cannot sign off the white chess. If there is no white triangle and one son, then when the black 5 is eaten, the white chess is finished.
Figure 7
However, AI believes that the actual combat white 76 is slightly conservative, and the strongest white chess piece is the direct turn of this figure, eating black chess, below the white 80, black chess can not hold any side outside the white chess for the time being.
However, this picture of white chess also has some hidden dangers, that is, the qi in the black chess corner is still relatively long, and the three sons of the white chess piece that are disconnected, the qi is not particularly long, and the white chess piece needs to worry about being threatened by the black chess with the white dragon below.
Figure 8
Now we return to this actual combat map, because the white 76 is not the strongest hand given by the AI, so the situation between the black and white sides is still very close at this time, which is the judgment of the AI.
But the problem is that people can't make accurate situation judgments, even top professional chess players, when there are still many unfinished places in the whole game, their situation judgment is more based on a feeling.
The whole battle above, a rough look, the white chess pieces eat the black chess pieces, and the black chess pieces are suppressed in the second and third ways, no matter how you look at it, it seems that the black chess pieces have suffered a big loss.
However, I hope you don't forget that black chess here is the first hand.
The benefits obtained by white chess here are obtained by white chess after spending a hand of chess, so if you want to make a relatively accurate judgment of the situation, it is necessary to estimate whether the benefits obtained by white chess here greatly exceed the value of a first-hand chess.
And more importantly, the formation of the black chess in this place should have how many benefits, and the interests taken by the actual black chess in this part have not obtained the benefits he deserves.
Only by synthesizing and analyzing the above three points can it be possible to draw an accurate judgment, but unfortunately, it is impossible for human beings to judge clearly in such a place.
But apparently, Lee Chang-ho and Cho Ji-hoon reached a consensus here: Bai Qi took the lead.
The basis for the two sides to make this judgment is that the black chess game is overestimated for the benefits it should have achieved, and the white chess piece is overestimated for the benefits it has achieved, and there is a certain gap between the estimates of both sides and the baseline given by the AI.
The reason why I have to spend so much time to introduce the situation judgment problem here is because it is the deviation of the judgment of the two sides here that has led to Zhao Zhixun repeatedly missing the road to safe operation in the next battle, because he feels that his situation is unfavorable, so he must fight!
Figure 9(77-88)
When the white 88 was sticky, the black chess actual battle chose the B pull and struggled to prevent the two sides of the white chess from contacting, which was the first strong struggle of the black chess, and it was also the first time that the black chess missed the opportunity to gain an advantage in a concise way.
The black next hand should be correctly a bit to eat, as shown in the following figure:
If the black chess is carried out according to this chart, the black chess can go to the good point of 5 first, and the black win rate of this figure is 90+, and the number of eyes is 6-7 mesh.
Figure 10 (89-92)
When the white 92 played, the black chess chose the A position to grow out, which is of course still implementing the idea that the black 89 disconnects the two sides of the white chess, but this is the second mistake made by the black chess.
Because the black chess has always felt that the battle on the right side has suffered a serious loss, therefore, even if the black 91 has taken out the white horn, it still feels that it is not enough, and it is still necessary to grow the A position to break the white chess piece, but in fact, the black A grows out, which seems to be a bit reluctant, at this time the black chess has a good chance to operate safely, as shown in the following figure:
Figure 11
Black chess is carried out according to this figure, although it seems to be connected by white chess, but also pulled out a son, but in this situation, the plucking of white chess is only limited to the number of eyes that eat a son, while the black chess piece can get the first hand to go to 11 good points, which is equivalent to the black chess first hand pulling the white chess corner of the empty to pay.
Figure 12 (93-105)
Although the black 92 or below successfully disconnected the white chess, but there are also hidden dangers outside itself, but this is not enough to lead to the defeat of the black chess, the real defeat of the black chess is the climb of 105, this hand chess should be done in the B position, Zhao Zhixun originally wanted to exchange cheaper hands with the white A first hand, but was hit by the white chess fierce counterattack, and won the black chess in one fell swoop:
Figure 13 (106-116)
White 106 breaks, a winning blow! The following to the white 116 is inevitable, and the black chess piece is suddenly in a desperate situation.
Next black 117 is a trap, if the white chess piece 118 is blocked, then the following to black 123, the white chess is a failure.
Figure 14 (118-128)
In actual combat, Lee Chang-ho chose the 118 tip, avoided the trap of the black chess, and went down to the white 128, and the horn became a wide one-gas robbery, which is actually equivalent to the white chess has killed the black chess.
Figure 15 (129-168)
Black 129 below is just a cutscene, to white 168, black chess regrets to admit defeat.
Lee Chang-ho also successfully entered the final, and finally defeated Ma Xiaochun 3:1 and won the championship of this competition.
