I think Elie has 6 greens that do this (1, 2, 6, 9, 10, 15) (and 5 slopes away at the front and up at the back. Of these holes 5 of them are "half par holes" to make the apparentlt easy birdie (2, 6, 10, 15) or save the tough par (1, 9) the player has to play a perfectly judged approach. Otherwise it can be tough to save par or bogey. On a relatively easy course like Elie, I think no-one minds this feature. Adrian is right, though, on a tougher course punters don't like being asked tough questions, particularly not with a short club in hand.
