One side will surround the other side after the attack, and make the other side only angry and have an artificial eye.

At this time, according to the current rules, the other party can't be in the eye. If the next son is self-promotion, take the image of the cow eating too much and inflating itself to death.

And the opponent can move the chess with one hand (in the position of self-lifting) after lifting the rear wheel.

As shown in the figure below:

Turn left | turn right

At this time, Bai can't go to A, so he has to collect foreign air, while Black eats and lives in A.

Another example is the following picture.

Turn left | turn right

White walk 1 bit play. Black can't stick either. If it sticks to itself, it has to collect gas outside and live in the middle of the artificial eye for nothing.

Please note that the above two pictures are just examples, which are more complicated in actual combat, but the reason is the same. The above answers come from Baidu.

In fact, if you want to look at pictures and get simple knowledge in this field, you can just use Baidu Encyclopedia.
