Ian Andrews' recent post on the merits of Huntingdon Valley, in particular the fallaway greens at several holes ensuring it is judgement of bounce and run that is important instead of a caddie's or laser guide's, accuracy, lead me to this topic.
Tom Doak, in Anatomy of a Golf Course, wrote that "a flat or slightly back-sloping green has instant merit because of the difficulty of stopping an approach shot... it is one of the few situations where the difficulty of the shot stands the test of time, because a short approach shot does not make things much easier".
Given the perpetual interest and intrigue, why does the back to front sloping green dominate more than the reverse?
