The purpose of this study is to deeply explore whether there is a correlation between the conditions when table tennis players play the role of tactical ability and tactical law in the competition. Research methods: video, case diagnosis and empirical analysis were conducted on the two dimensions of traditional technical and tactical playing methods and connecting technique theory of active world champion athletes with different playing methods by conditional analysis, find out the factors that affect their tactical ability. The results show that the conditions under which the tactical law of table tennis works have little effect on a very small number of dexterous athletes, The main reason is that their playing methods and tactical awareness are similar to their connecting technique awareness, Therefore, their tactical ability in the game is related to the connection of connecting technique consciousness, and they are the people who are closest to the requirements of balanced technical and tactical play in the “40+” new era; Most of the athletes, especially the strength athletes, lack the sense of connecting technique, and the conditions when the tactical law works have a great impact on them. Therefore, there is no correlation between the exertion of their tactical ability and the sense of connecting technique in the competition. Research conclusion: connecting technique is not only the key to improve the tactical ability of table tennis players, but also the theoretical basis of tactics. It is also the main condition for the action of tactical laws and the scientific method for professional identification of whether athletes have tactical consciousness, only when athletes master the connecting technique can the use of tactics come naturally.
