Is golf a sport? Is bowling?
What about darts? Snooker and billiards? Diving? Synchronized swimming? Teen beauty pageants? Cheerleading? Gymnastics?
I say "yes" to some of the above and "no" to others, on the basis of certain CRITERIA. It depends on the criteria that you're using under the definition of the word "sport". I'd rather that chess be considered a LEGITIMATE COMPETITION and leave the definition of sport to some other day; and I'd rather that anything with a major proportion of judgement-call involved in determining the victor, to be REMOVED from the category "sport." Diving, for instance -- not a sport. But it's a DISPLAY and it CAN be relatively competitive, but it is NOT always possible to provide for an ABSOLUTE competition with winner and loser since the victor is determined solely by judgment-call ("the scores are coming up: the US judge gives a 3.5, Japan 3.5, France 3.4, Brasil 3.6, and a ... yes another 9.9 from the Romanian judge for Eslvaolu the Romanian diver!").
