Poker should never be an Olympic sport.
Even if we consider it a sport, should it be an
Olympic sport? That's the main question 'cause there are thousands of sports out there, but only a few of them are Olympic sports.
Olympic motto:
Faster, Higher, Stronger - Together
All Olympic sports are physical sports. The mental sports that lack physical activity don't fit. The eSports involve a lot more physical activity than poker, but they are not there yet. That will change in the future, especially considering how the virtual and augmented realities can spawn many physically demanding eSports. On the other hand, it's not easy to turn poker into a physical sport without changing it completely or by making it last too long for an Olympic event.
Last but not least: although poker is far from a game based entirely on chance, the luck factor is too strong for a short competition like the Olympiad. The luck has an effect on many of the Olympic sports too, but most would agree that it's nearly impossible to win by luck alone, while in poker you can do that.
