What qualifies as a "sport", and what disqualifies a "sport"?

[GTripp0012]

To me, a sport would entail (and I've taken an entire college course based around this question) any activity that involves competition, rules, and requires physical or spatial/locomotion acumen.

Auto Racing, so long as it is competitive and outlined in rules, would be a sport because to be successful, one needs to perceive the physics and movement of all the other cars around them, in order to pick the correct move and it's done in real time. Golf, by the same definition, would also be a sport, in the sense that one must perceive the flight of the ball prior to it being struck, and then actually use physical force to move the ball.

Chess is not a sport by this definition, because the physical/locomotion aspect is a non essential feature of chess. If the pieces were robotic instead of moved by the players themselves, it wouldn't really take away from the game at all. Same thing with poker.

So Car Racing/Golf=sports, Poker/Chess=non-sports.
