Patrick:
Regarding #2 and #8 at ANGC, I am speaking from the point of view of the tournament players. I haven't reached (or even tried to reach) a par 5 in two shots in years.
Over the past 45 years I have witnessed at least 700 shots into #2 and slightly less to #8. The approach to those greens has changed over the years as the players have gotten longer and the tees have been moved back. For a long time most players hit drivers off the second tee, and the longer players could go for the green with a middle iron. In those days, most would go for the green regardless of the pin placement. The tee has now been backed up so far that if the pin is left, especially if the wind is against, most players hit a fairway wood off the tee to avoid the fairway bunker on the right, thereby leaving a longer shot to the green. If the pin is left, there is little percentage in trying to hit the green. If they clear the left bunker, they probably wind up over the green, which is not good. If they play to the middle of the green, the slope takes the ball right leaving a very long and difficult 2-putt and a likely 3-putt. I did see Nick Faldo make a 90ft putt from the right one of the years that he won, but I have seen many more 3-putts from there.So, most players will play their second shot short right, perhaps even right of the right front bunker, leaving a simple pitch shot to the left pin. The other option is to play into the left front bunker. I'm guessing that the at least half the birdies I have seen on #2 were from the bunkers. Not many from over the green.
Now, if the pin is right, almost everyone will take a crack at it in two. The perfect shot is aimed to land between the bunkers, bounce onto the green and roll right to the pin. That's exactly what Louis Oosthuizen did. If the shot misses right into the bunker, no problem. There is still a better than even chance of a sandy birdie. Just don't miss long.
Until recent years, very few players attempted to for the 8th green in two. The risk of getting a little left and winding up behind the large mound on the left, leaving a blind and difficult pitch, outweighed the reward. They have moved the tee back and extended the fairway bunker forward, but these days the players are so long, that many will take a crack at the green, if the pin is on the front half. Still, if the pin is back left/rear, most will elect to play well right of the green, toward the 9th fairway, leaving a much easier pitch to the back pin. There are, of course, exceptions, but those rarely are made by the veterans.
By the way, I also agree with Bogey, that you are more likely to see a layup to the right when the pins are on the left corner of #13 and #15. The risk of going for those pins in two is too great, so the only other option is to go for the fat of the green. That option also has more risk that reward.
As I am sure you know, anyone who thinks a pitch shot from a downhill lie over the water on #15 is simple, should ask Greg Norman.
