I like this topic. Though each player will have their own opinion to say the least.
Unfair -
1) Hole locations on severe slopes.
#18 at Olympic for Payne Stewart years ago.
I played in a college tournament w/ the slope on #6 Coto de Caza where putts from below the hole would come back 15 feet. That was unfair, though I was only one in the group to one putt
.
#16 North Berwick - If I were Open qualifying there and 3 putted, I'd probably call it unfair.
2) Bunkers that funnel into an 8.5" X 11" piece of paper.
Rustic Canyon #8 front left bunker is little too severe.
David Duval now thinks #17 TOC Road Hole bunker is.
3) Par 5 tee shots that zero out options.
Some cape holes end up too severe.
#14 Meadow Lake Country Club in Escondido.
I've learned "to chip" a 4 iron off this tee.
Ladybank in Scotland hole #7(I think?)
Go ahead and ask what the Open qualifying scores are like there.
I see David Moriarty's point, but there is some merit to this topic. Not every course should be a "match play" course.
Consider this stroke play e.g.
#10 at Pauma Valley CC. 370 yards uphill w/ a fairway that is 15-20 yards wide. The green has a steep bunker in front and mamy of the hole locations on the green are unusable. In a past US Open qualifier, they had a bad hole location - Many of the entrants decided after 3 or 4 tries to take the "ball in motion" penalty and knock in while it was around the cup.
Unfair? Yes.
Disclaimer: I love Pauma Valley and the 10th when the hole location is in a reasonable.
#10 green at Shinnecock is good example of severity.
Some of the hole locations there are dangerous.
