Chapter 749: The hero looks back and revisits the classic - Cannon Victory Double Soldier
Figure (749.1)
After learning chess for so long, we know that there are many examples of victories and endgames in chess, and although these endgames are still circulated in pictorial form, they have consolidated the foundation of chess. Why there is a certain formula remains to be studied, but the investigation as a chess power is still convincing. For example, can a single cannon win the opposing general's double sergeant? Anyone who has ever had the basics knows that the answer is yes.
So why can the cannon win over the double sergeant?
As shown in the picture, this is the model that the general teacher uses to pay attention to the cannon victory when everyone is studying. The cannon can win the single sergeant, on this basis, the so-called cannon victory double sergeant generally means that the cannon can use the help and cooperation of its own sergeant to first destroy the other sergeant, so that the opposing shuang can become a single sergeant, and then break the single sergeant and win. So how to crack the two soldiers who are jointly defended by each other?
1. Servitude 5
Draw 4 with 5
2. Shi 5 into 6 (The reason why the red side is transferred to this side is because it can do the gun mount to control the actions of the black general in this rib)
Figure 2)
As shown in the figure, it can be divided into three situations: black will be in the left and right ribs and in the middle. As shown in Figure (1) At this time, if the red side goes, it will directly take the next 4 rounds to occupy the right costal road, so that the black will not be able to move left on the rib line of the black warrior, forcing the place to the rib line of our taxi, at this time, it is not with the help of the red side to continue to attack the black general, because the black is in the middle of the double interconnection, at this time can occupy the middle to force the double to disconnect. (2) If the black will be at the rib of the red line at this time, it will directly level the cannon in the middle, and the reason behind is the same. (3) If the black side goes at this time:
Will 5 draw 6 (black side walking will also keep the double interconnection)
Figure 3)
At this time, the red side should not directly flatten the general, because as long as the interconnection of the two sergeants is not broken, the role played by the general will not be achieved.
3. Cannon three flat six (At this time, the red side should control this rib with the help of its own warriors, control the black will make it impossible to come to this rib, control the black warrior can not come to this side.) Do not give the other party the opportunity to adjust the position of the double. ）
Will 6 draw 5 (The double can not move, forcing the black will return to the middle again. ）
Figure 4)
At this time, the red side still can't directly general, because the black general can go out of the red rib line, can't destroy the interconnection of the two soldiers, and does not contain the black soldier, so he can't break the first sergeant.
4. Cannon Six Flat Four (Control the Horn Soldier Rib in order to block Black will return to this side again)
5 draws 4 (This is the winning situation, the black side of the horn and the three are located on the three lines in the middle, there is no black soldier in the first line formation.)
Figure 5)
The picture is a model of the red side being able to break the double warrior, and the reason why it is successful here is that it can force the opponent's red marshal to play the advantage of occupying the middle and contain the black side behind.
5. The gun four flat five () gun control the middle road, the front is to pave the way for this step. The first two steps are to avoid the black will be on the side of the Black Horn when the Red Cannon is in the middle.
Taxi 5 into 4 (The black will not be able to return to the middle to be controlled in the rib passage, and can only adjust the rules that the taxi should take one step on one side.) The black general above cannot be without support, because once the red general otherwise the black will have difficulty staying in the ribs. At the same time, due to the transfer of the taxi, the middle road could not be returned, so the taxi could only go above the black general. ）
6. Cannon Five Flat Six (Back Rib Road Fighter)
Taxi 6 back 5 (double company)
7. Cannon six retreat one (stop, the original line stays to contain, seems to be mobilized but does not leave the original line to continue to maintain aggression)
Will 4 draw 5 (if the taxi is moved, the horn will be lost.) If the black general is in the double semi-encirclement last time, it will form a dead frame and be used by the red cannon, so he has to return to the center)
Figure 6)
8. Cannon Six into Seven (Finally Derby)
Seeing this, do you feel that you have learned and understood why the cannon can defeat the double sergeant, really? You know, just like going to school to study, the teacher explains that the A exam is but the test is B, it is better to give an example to test and try the amount of absorption.
