Li Kaixian is a chess player and has never had an opponent in his life. Although he was obsessed with chess since he was a child, chess was only a sideline for him, but his chess skills made those professional players look invincible at that time. He also wrote many poems describing the scene of playing chess. For example, in "Chess Saints Wu Juyin and Wu Shengfu", he wrote: Although the national players push and shove, Qiang Bing is unique. Every time, it is difficult to succeed, and if you give a horse a break, you lose.
Wu Juyin and Wu Shengfu were famous chess players at that time. Li Kaixian gave them the third place, but they were no match at all. If they are allowed to play alone, they often can't win one or two games. At that time, a famous chess player in Yanjing once defeated another famous chess player, Zhang, and caused a sensation all over the world. However, Li Kaixian's chess skill is better than that of Chen Zhen, a world-famous national player. He often gives him a rest during the game. But even so, a year later, Marco has always been defeated in countless games between them, and he can only play a few games on foot, but he has never won a game on Li Kaixian. At that time, someone praised him: only this ability can be high in ancient and modern times.
