Japanese Go Rules, Korean Go Rules and China Go Rules have different regulations on "four corners". ? Japanese rules stipulate: "bend four corners and the game will die." The premise is that the chess outside must be a live chess. " In other words, it is difficult to stipulate that the "four corners" are dead chess. The provisions of Korean rules on "coiled wire" are basically the same as those of Japanese rules. ? China's Law emphasizes that life and death are confirmed by actual combat. If it is a live chess, it will definitely not be killed; If it is a dead chess, you can kill it. For example, whether you are dead or alive in the end can only be decided according to the actual situation, and there is no need for hard and fast rules. Both sides think it is a dead chess, and disputes will be solved in actual combat. It is believed that the "four corners of the plate" is that the dead chess player makes up for the robbery first and then kills it; If you have a live chess, you can't make up for it and don't want to rob it, then the "four corners" are live chess. ? China, Japan, and South Korea have made different regulations on "coil angle bending wire". The fundamental reason is that China rules use "number method" to calculate the outcome, while Japan and South Korea rules use "number method".

Edit this paragraph's disc angle and Song Si's specific introduction.

1. The general result of the four corners of the chessboard: Generally speaking, the four corners of the chessboard are dead. Although there is robbery, the robber can make up all the robbed materials first (without duplex), and there is no other way but to wait for death passively. Therefore, there is a famous saying: the corner of the dish is four, and the chess is destroyed. ? 2. The special case of Pan Jiaoqu 4: Generally speaking, Pan Jiaoqu 4 is a dead chess, but there is also a special case of live chess in theory (this special case has not appeared in the current professional competition)-Pan Jiaoqu 4 plus a double activity (of course, the value of double activity is greater than Pan Jiaoqu 4). The fundamental point is that other robbery materials can be compiled, and the double-live robbery materials can't be compiled anyway. In this case, the result of the four corners is a living chess.
