Ed,
For me everything works back from the greens; the features you mention "interact" with them to produce the difficulty.
For example, what makes the greenside bunkers so difficult is knowing what will happen to the ball on the greens. Then you start thinking and it's all over.
My adventure one round on the short par-four 3rd on the West went as follows:
Flag back right, so I think I should hit a layup drive down the left side. Unfortunately, I "succeed," and from the fairway now face a little shot of 60 or so yards looks perfect for a pitching run up, only there's a swale in front of the green running from front left to back right. (It's a fall-away green so I don't want to try the all-air route. Next time I resolve to try my luck from over the green, but that's another story...)
I notice a reasonably flat space to the left and figure if I can sort of just bounce it up through there, the ball will roll out and as a bonus maybe the beginnings of that swale will gently draw the ball right and towards the flag.
What a complete waste of thought! Fixated on the swale, I proceed to push my little running pitch just left, where -- oh no, there's a bunker over there! -- the bunker just barely pulls it in. I don't completely realize it yet, but this innocent-looking bunker is a widow-maker...
(Meanwhile, my playing partner has made the proper play, having driven out to the right so as to face the swale at a right angle.)
Although I have an ocean of green to navigate, and the bunker is not particularly menacing -- I notice there's not much sand in it and what there is, is very packed -- I know from previous play on the hole that if I can't spin it out of the bunker it will run a mile. So the shot looks long, but plays much, much shorter.
I don't want to risk a scull in the hard-packed sand, so I play more of a squared-off bunker shot. Knowing I need to barely get it on the green and it will run and run and run, I hit a shot that only just fails to clear the lip, and like the shot before it rolls around the face before settling down to the bottom. Now I'm 10 feet closer, but somehow feeling worse off -- how could I make such a dumb mistake as driving it down the left side! Why did I challenge that bunker!
My next shot just barely lands on the green -- juust makes it on, can't be more than a little three-foot carry -- and doesn't race down, but impressively for its relatively slow speed, doesn't seem to want to stop. Whoa!
Two putts from there for a -- wait, I can't have added that right, it's just a dinky little par 4 -- psychologically deflating double!
After that traumatic experience, the bunkers start to look differently. You start thinking, "does every out-of-position approach involve carrying a greenside bunker?"
And forget what everyone says about how huge the greens are. They only look big when you're on them; they look a lot smaller from the tee and / or approach due to how the bunkers eat right into them, a fascinating feature that's a MacKenzie special.
I think it gets worse the more you play it; the first time around nothing looks so dramatically fearful, with a few notable exceptions. (Left bunker on 10!)
In short, Ed, you're meat! It's going to take your game apart! Play to the middle of the green and spend all your waking hours practicing speed putts!
There's no hope for you -- at some point the course will get you and leave you muttering about "How could I miss that fairway!" and "One of these days I'll get it to the hole" and "Time for the hand wedge."
Cold comfort will be the members who remind you Ernie Els couldn't get it out of there, either, or Allenby threw away a big check from right where you're standing...but remember, it's better to be in a greenside bunker than to be wide of it. From such locations, you might as well just aim for the bunker on the opposite side, because that's the only thing stopping your ball.
Have fun!
