What does robbery mean in Go?

Robbery refers to black and white pieces around each other. In this case, if it turns white, you can eat a sunspot; If it gets dark, you can also eat a Bai Zi. Because there is no solution to this cycle, it is forbidden to "isomorphic repetition" in Go. According to the rules and regulations, after a son is "lifted", the other party can't immediately lift it back. You should make a move somewhere else first, and then "lift" after the other party should make a move first.

As shown in the figure, when it was Bai's turn, Bai raised a sunspot in position A; At this point, the black side can't immediately mention Bai Zi in position A, so he must look for a trophy, that is, play the next move elsewhere, and then he can mention Bai Zi in position A after being answered by the white side. However, not all robberies will lead to the other side being alone. In the case of value judgment, the other party shall not rob and solve the robbery dispute. "Robbery to win" is also called "robbery to destroy".

Extended data:

In 2005, in the semi-final deciding game of the World Go Open in Samsung Cup, Chinese player Luo Xihe played against Li Changgao, the first Korean player (who was also the first in the world at that time). When there is a three-robbery cycle that no one is willing to give up, and many professional players never meet once in their lives, everyone thinks that a draw rematch is inevitable, but Luo Xihe gave up the robbery in amazement! After his white chess was eaten by 46 children, Luo Xihe won with 7.5 goals. After this battle, Luo Xihe was called "robbing the king".
