I think that the only things that are 'unfair' are things like blind bunkers in the fairway on a course that gets mostly non-member play or blind doglegs and stuff like that. Those type things are unfair. Anything that if you hit a good shot leaves you with nothing at all, no play, out of bounds or something like that is unfair. Greens are not unfair, if you can't be on the right tier of a green, you just hit a poor shot, or are generally a poor player. Donald Ross greens are not unfair, if you manage to find one of his runnoffs, you hit a poor shot to get there. Very few times have I played a course where I thought it had shots that were unfair.
