Ian:
The most interesting holes to watch the young pros play at Cape Kidnappers were the par-fives.
As it turned out, it was the 16th hole more than any other that separated them from each other, even though it's a very short 5 and A.K. had something like an 8-iron into the green ... in fact, at 490 yards, he didn't even realize it was a par five. The four players made 3, 4, 4, and 5, but Snedeker's poor tee shot and Mahan's great putt (after a slightly hedged second shot) turned out to be the difference.
The second and fourth holes were equally fun to watch, because they were the only holes that the guys had a long club in their hands for their approach shots. Both holes give you a bail-out left (with a very difficult chip) and both have a bunker at front right, so when the guys took enough club to get over the bunker AND hedged left ... which three out of four did ... they beat themselves.
320-yard holes and 580-yard holes are the ones which will be most exciting to watch the pros play. And yet most architects keep building 490-yard par-4's which are impossible for the amateur, but only difficult for the pros if they drive it into the rough.
