Is poker a mind sport?

Poker still requires brains, thinking, and reading and memorizing the cards that have been dealt. It's still a mind game, isn't it? But is it a sport?

from reading this, poker is not only a mental game, but also a sport!

An extremely fascinating and engaging discussion. I must say that the more I have played poker, the less I consider the element of chance in this game. So I have nothing against considering poker a mental sport, since the proportion of skill and luck in a long tournament is clearly in favor of the former, or so 80-20. But of course everything depends on the definition of a mental sport. If we use Marten's definition - there is no randomness - then poker of course does not qualify as a mental sport. The question again is whether this definition is the best. Personally, I would not be so strict and would also allow a certain factor of chance, but the skill factor must of course be clearly dominant. This would also allow games such as Entropia to be classified as mental sports, because although the element of chance undoubtedly exists there, it is still very small and can only become decisive for the winner in a game of equal strength players. This in turn leads to the question of what does clearly dominant mean? How much randomness should be allowed and how to determine this percentage in different games is an extremely complex challenge. Marten's definition with its zero tolerance is better in that such a question does not arise. What are the main properties of classical mental sports such as chess, checkers and go? They are all deterministic, antagonistic games with complete information, where the resources used for the fight are equally divided between both opponents. Poker differs from these classical mental sports in several aspects: poker is a stochastic non-deterministic game, the information is not complete for any player (information is also asymmetric in the classical sense, but its amount is symmetric), and the allocation of resources used may not be fair. Thus, poker is not a classical mental sport, but this does not mean that it is not a mental sport. It all depends on the definition.
