Phillipe,
Thanks for getting back on target with this, as I'm looking at the topo right this very minute and it is rather quite obvious the mound is a very definitive feature of the hole when it comes to the strategy of playing the hole. The green is evil & wicked enough that going to the right is almost like accepting the fact your not going to one-putt, but that left side of the mound with the green, it will funnel the ball to a host of positions worthy of Defence of the putting surface. (something Wethered & Simpson wrote about extensively)
Simply put, that left side for me is a Sportsman's shot. Many don't try it on purpose--at least I never really saw them do it much, but I'm sure Tom Doak and Brad Klein should know the hole pretty well from their bag-totting days abroad.) The penalty isn't much if you can't pull the shot off, it only adds a couple of strokes should you not get it by the mound or take it to far away from the slope to the lower section of green. MacKenzie talks about it in Spirit of St. Andy, how Joyce Wethered found birdie there more then any he had seen play the hole in all of his visits there.
God, I love that place!
