I am not a big fan of totally blind shots, however if they are well done, I'm not necessarily opposed to them. However another type of blind shot to consider is the nearly blind shot
For example, one I am very fond of is #7 at Camargo, with its sunken Punchbowl green, but you can just see the tip of the flagstick. (See Ran's photos from his Camargo writeup). While you can barely see the tip of the flag, you can see nothing of the (enormous!) green and its surrounding bunkers. Furthermore, you dont have a clue where you ball ended up until you're almost to the green. Great hole!
