All right. Chess brush brother is the gold medal chess anchor certified by Tik Tok's official real name. He began to learn chess at the age of 5, and studied under a famous teacher. He has 40 years of practical teaching experience in chess. The opening layout of the actual chess teaching, the chess player in the middle game, the chess flying knife and the residual chess attacking and killing are the chess saints. In the actual live broadcast, all kinds of layout explanations are thoroughly analyzed. Personally, I think it is the level of industry 9, and the strength of provincial experts is very high.
