I once heard Jack N talk about the Strategy of Pinehurst No. 2. He was surprisingly focused on "There's a fw bunker left, and of course, you want to miss that" vs. thinking about the best angles, etc.
And Pete Dye is famous for saying "Once you get them thinking about where to miss, those dudes are in trouble."
Lastly, with new equipment, the "open front" green isn't that big a deal as it was when things had to run in. Some players prefer to come in from the same side as the hazard, figuring, like taking a stance near OB on the tee so you can aim further away from it, they can aim further from the hazard. Even if you prefer the open front approach, its so that when you are between distances, you can club down rather than up to get an easier uphill putt, and still hit your standard shot.
I suspect its about knowing where to miss, avoiding anything that could cost you one or more strokes. As in football, playing defense wins championships.......
