Chess System Theory: Homotropy is used in one way2

One party seems to have a multi-purpose magic hand, but the other party has the same magic hand. So the result is not good. This shows that in the process of chess, we must not let our thinking lose one-sidedness, know ourselves and know the other, and only pay attention to one aspect of the contradiction and do not attach importance to the other.

Example 1 shows an endgame shot of Liu Dahua and Shanghai Lin Hongmin in the 1983 National Individual Competition. Now that the red side is using the power of the draw to deceive the car with small soldiers, the black side is in a very difficult situation. In actual combat, the black side wanted to borrow the departure function of the cannon 8 into 5 photos, and took the machine gun to the car 9 flat 7 to follow the red cannon, but it was unexpectedly used by the red side in the opposite way.

Example 1

1....... Cannon 8 into 5?

2. Car four back eight! ......

The cannon mouth of the red party retreating car feeding is also a two-handed salute. Its placeholder function is used for interpretation, and its out-of-place function is used as a reflection. Now the black side must be dismantled, which will cause the cart to become the food of the creeps.

2....... 4 out of 1.

3. Soldier one into one, pawn 1 into 1.

4. Cannon three retreat seven! At this point, the black side admits defeat.

Because of the following red cannon three flat four, shuai five into one, wait for the black cannon 8 flat 6 eat the car after the marshal five retreat one to catch the black cannon chess.

Example 2 When the 1988 National Individual Championship (Women's Group) reached the last round, the two major players of the strong Hebei women's team, Hu Ming and Gang Qiuying, encountered themselves. Former teammates are now opponents, and this chess seems to be very difficult to play.

Figure 2

In fact, the same room really does not move, which is not uncommon in the confrontation of the court, and they are now the same. In this game, when the situation in Figure 2 is the turn of Hu Ming, who is black, to go.

1....... Car 2 into 3?

At this time, although the bottom line of the car has a three-purpose (catching the phase, protecting the cannon, and making the 2-way horse catch the red car), it is counterattacked because of the excessive force of the blind attack. If you do not miss the red square under the return of the magic hand, at this time should actually change the car 2 flat 4, can become a general balance!

2. Cannon six into seven...

Even if the two sides are connected, the other side is lost, thus forcing the other side to rescue the cannon seven into eight suffocations, and the red side thus gained a clear advantage. The following black side has become increasingly passive due to the attack on the cheri and horse artillery.

2....... Like 3 into 1.

3. The car nine into two, the cannon 6 into 1.

4. Cannon six flat nine, pawn 7 into 1.

5. Horse four retreat six, horse 2 retreat 1.

6. Horse six into seven, like 1 into 3.

7. Soldiers seven into one, horses 1 into 3.

8. Horse seven into five, cannon 1 retreat 8.

9. The car nine into the four, so far, the red side is already in sight of victory. However, it is a pity that Hu Ming lost the opportunity to regain the championship because he lost this last crucial battle.

Note: The first black car in this example has three uses, namely, to catch the phase, to protect the cannon, and to promote the 2-way horse to catch the car, the former belongs to the catch function, the latter belongs to the out-of-place function, which is easy to understand; but does the word "protect the cannon" give birth to a new function? In fact, the well is not so, because protecting one's own son from being eaten by the opponent's chess pieces, which should be a special manifestation of the control function from the essence.

Example 3 shows a wonderful scene in the 1982 National Individual Competition, where Lu Qin and Li Laiqun encountered a wonderful scene. The red side went up and the horse seven retreated nine to catch the black cannon. Originally thought that the black cannon 2 flat 5 call will be drawn out of the car can not be established, because the red has the means of five cannons into three anti-generals. In fact, at that time, Lü Qin just missed the red cannon five into three, and the black side continued to hide the magic hand. Therefore, the shots of this example, such as the photo general, the anti-general, and the anti-general, are particularly wonderful and moving!

Example 3

1....... Cannon 2 flat 5.

2. Cannon five into three, car 2 flat 5!

At this point, the black side has won.

Dynamic chess score for Example 3

Because of the next red horse seven retreat five pedal car, black cannon 5 retreat 3 re-shooting (this is the third one-to-multi-purpose), after the red party to supplement the soldier or elephant, you can use the position vacated after the cannon 5 retreat 3 to take the gun 8 flat 5 shots (the fourth one is multi-purpose), so that you can eat back a car, earn a horse in vain and maintain a strong offensive. Due to the multi-purpose of the above series of one-on-one, the speed of change in the situation on both sides is like a sakami pill. It's dizzying. Here, the peculiar effect of multi-purpose and its inherent artistic charm are fully demonstrated.
