For me the answer is very clear, and it is that poker is a "mental" sport like chess, and it does not require physical efforts like sports, they simply fall into another category, but to say that poker is not a mental sport. It is like saying that chess is not either, and since physical sports have many similarities and one of them is that they are competitive, where there are winners and losers, where there are rankings, there are prizes, and where the best wins, they are different categories and that's all
