Sports Ethics Class

My thanks to the reader who sent me the following very interesting ethical dilemma:

Say you're playing in the club championship tournament finals and the match is tied at the end of 17 holes. Say you hit your ball 250 metres to the middle of the fairway, while your opponent then hits his ball deep into the woods. Being the gentleman you are, you help your opponent look for his ball.

Just before the permitted five-minute search period ends, your opponent says: ''Go ahead and hit your second shot, and if I don't find it in time, I'll concede the match.''

So you hit your ball, landing it on the green about 3m from the pin.

About the time your ball comes to rest, you hear your opponent exclaim from deep in the woods: ''I found it!'' The second sound you hear is a click, the sound of a club striking a ball, even as the ball comes sailing out of the woods and lands on the green, stopping no more than 20 centimetres from the hole. 

Now here is the ethical dilemma: Do you pull the cheating bastard's ball out of your pocket and confront him with it, or do you keep your mouth shut?
