When it comes to the rules, golf is really unlike any other sport. What other sport can you name in which you call penalties on yourself? Most sports have a referee and it is almost an art to cheat until you are caught. Just watch any NFL game and watch the linemen battle it out and likely you will see holding or some other mischievous activity on every play. The NBA is the same way with all the pushing and elbowing. As long as the ref doesn't call it, you are free to do it, even encouraged. In golf, if you are in the trees and your ball moves while you are addressing it, it's on you to call the penalty on yourself.
This brings me to what I really want to discuss, which is cheating. In golf, cheating is typically done as subtly as possible. There is a decent amount of blatant cheating which I will discuss, as well as numerous cases of just not knowing the rules. I am forced to admit that the rules of golf can at times be confusing for the average player and this can lead to some heated discussions.
