It is odd how if you are participating it is not gambling, but if you are observing it is. For example with golf, you can pay an entrance fee for a tournament and have a chance to win and most would not cosider that gambling. On the other hand, if you bet on the winner of that same golf game as an observer it is gambling. What if you bet on yourself to win? Mixed bag, the whole thing. By this perspective, getting together with the guys and playing poker should not be considered gambling, but most people would call it such. In fact, if it wasn't an organized tournament with a prize, but just two groups of people challenging each other to a game of basketball with both putting down a given amount of money, most would consider that gambling. I guess it all comes down to the mentallity which makes it hard to define if it is gambling or not since it will depend on the individual. If someone views it simply as paying for the oportunity to play in an organized competition, it wouldn't be considered gambling. If someone is playing for the money, to me it would be considered gambling.
