I think a lot of people are surprised by the elevations at Augusta - it must be 200 feet down from the clubhouse to the bottom end of the course.
This hole swings around the trees down the hill and then you go across this big valley to a raised green once again.
This is where I've seen some of the cruellest second shots. Somebody plays up just beside the pin and you think "That's a beauty" and then it takes just that little extra bit of spin, it comes back off the green and ends up 50 yards short down the fairway. It happened to Greg Norman when he lost that six-shot lead in 1996. He didn't do much wrong and it cost him dear.
And of course other times you get a shot which is hit too hard, sometimes by as much as two clubs. It just bites on the right spot of the green at the back, maybe bounces on the fringe, the spin takes over and suddenly the ball begins dribbling back and ends up stone dead. There's quite a lot of luck attached to the second shot on the ninth.
