摘　　要：Karate is a competition combat sport that will be present at the Olympic Games during the trials in Tokyo in 2020. Within its inner logic, this activity implies a system of scores that may lead to a specific modelling, to be unveiled and used when dealing with the search for performance. If we consider that various strategies all seem to be able to lead to victory within that zero-sum game, might there be a possible Nash equilibrium to look for, aiming at favouring some of them and minimising gains and losses？ Must one privilege offensive or defensive behaviours, provoke or wait？ In relation to new sporting rules, 309 combats have been observed in the light of their system of scores and our result reveal perspectives for training. Even though the results remain questionable and are still to be completed, they enable us to highlight propositions as to a modelling through the work of Biechy. The suboptimal equilibrium thus highlighted reminds us that this game remains solely based on a system of rivalry, within which predefined strategy and initiative are to be articulated.
