Moreover, the wallet is a small platform. I feel that it is not as safe as ZB, but some personal wallets can be used with some amount

7. In go, the outcome is determined by the number of intersections. The intersection is the result of the intersection of 19 horizontal lines and 19 vertical lines in the chessboard × 19 = 361 points. In technical terms, these points are called "Mu" or "Zi". The last side with more mesh or sub number wins. But generally speaking, the black side should first paste 7.5 mesh to the white side to balance the advantages of the first hand, that is to say, the white side should add 7.5 mesh to compare with the black side. Note that the meanings of "Mu" and "Zi" are different from those mentioned above. Here, "Mu" and "Zi" refer to two different methods of calculating the outcome. Either method can be used, and the meaning is the same
let's first talk about the calculation method of "item": the difference between the number of items on both sides, such as 180.5 items on the black side and 180.5 items on the white side, is that the white side wins 7.5 items, because the black side has to post 7.5 items first
let's talk about the calculation method of "sub": half of the intersection point is 180.5 + 3 + 3 / 4 (half of 7.5 mesh). If one party wins by more than this number, the number of sub winning is the difference between the number of sub winning party and 180.5 + 3 + 3 / 4, which is the same as the above example, that is, white party wins 3 + 3 / 4.
