Hehe. In fact, I had just visited that page before posting. But the first definition is primarily the one people go by --
"an athletic activity requiring skill or physical prowess and often of a competitive
nature, as racing, baseball, tennis, golf, bowling, wrestling, boxing, hunting, fishing, etc." The key word here is "athletic". Table tennis can definitely be argued to be athletic since it requires dexterity, but not chess. That said, chess is great. What about poker?? That should've been the first game to come to mind.
