TEPaul,
Isn't the scariest shot the one with the potential for the most disastrous consequences resulting from a misplayed shot ?
# 18 NGLA, strong wind, crossing slightly in your face, pin ALL THE WAY BACK, your score for the first 17 holes, the best you've ever played, your opponent, a world class player, playing one of his best rounds, and you're all even, and.... after being overserved the night before, you foolishly bet your life savings, house and wife on the outcome of the match, well, let's make it really tense, you only bet your life savings and your house on the match.
Now, you and Chipoat tell me, is that a scary hole ?
Is the third shot one of the scariest in golf ?
Now, same hole, same wind conditions, and you, Chipoat, myself and a fourth are having a casual match and a good time, it's still scary, but the consequences aren't as dire, our attitudes not as fearful.
Hence the scariest hole in golf begins between our ears, the physcological influence of our individually perceived predicaments and surroundings and the consequences of our misplays determine the answer for each of us.
