"I just did some checking and they must play a sudden death format if there is a tie in Stroke Play. So this explains why he did what he did in order to accomplish his goal. It may not have been pretty, but the goal was completed." Eagle
So a playoff was indeed required for the match. Having considered this a day and read the jist of comments, I'll throw this out. There is a way to concede the match by not being so obvious. If I wnat to "let" the other guy win, I can easily do so without the person having the "in your face" way of drilling a drive out into the range OB. In some regards I look at the "sportsmanship" as a somewhat selfish way, because clearly some people would (as indicated here) send kudos for the "selfless act."
But as a competitor myself, if I won this way, I would always second guess my own talent and ask if I really was entitled to go to the big tournament. And so in that way I would personally be a bit miffed because I would feel I didn't earn it, and was in some was cheated out of the possibility of winning straight up.
If we all step back a moment and think about it, all the chatter on line and even here on our FJ site shows that there is some angst in what was intended and what the final outcome really has become. I say again, while his heart was in the right place, some of this just doesn't bounce in his favor...
