I have always understood the Eden to represent options. If the hole location was directly behind the Strath bunker it required an exacting shot if you chose to carry the bunker. The Strath didn't protect the entire green only a certain pin location with a smallish bunker Other options are to play over cockle or roll it up left of the strath using the steep approach hoping it doesn't roll of the back of the green. Three options using one shot. Maybe simplified but my take. I can't remember such a small bunker protecting such an important pin location. Maybe the 17th at Sawgrass or The Devils @#$% at Pine Valley.
Jim, Thanks for the response, sorry it took me so long to see it.
I am still not sure I understand how the Strath is so different from a multitude of bunkers in the world of golf that are deep and protect a tough pin that "requires an exacting shot" and creates options relative to how to attack or play conservatively.
I don't have much experience at St Andrews, having only played three rounds there, but to me the big thing that stood out with the eden hole was the slope of the green and how few usable pin placements the green had. Also, the skyline effect of the green combined with that slope makes going over seem to be death. (never got back there to really know what happens, and score wise I am glad of that!)
Obviously the slope of the green and the strong desire to stay below the hole ( no option to bail long) brings the Strath bunker more into play than most bunkers protecting a tough pin placement on other holes throughout the world, but that still makes me think the slope of the green is more a factor than the actual bunker.
Hopefully you, or someone, can further educate my simple brain on this, as I am still not really comprehending what you were saying about the importance of the Strath bunker.
