I appreciate the discussion.
I often have thought that as a general rule fairway bunkers should be deeper. Deeper fairway bunkers present more of a dilemma to the player regarding whether to aim away and, once in the bunker, whether to wedge out or risk the lip to get it on or close to the green. For the lesser player, a conservative wedge out might yield better results than trying to be a hero.
I think green-side bunkers could be less deep. For the better player, I believe judging the sand is the biggest challenge for a green-side bunker shot. There is a bit of randomness regarding whether a ball checks or runs out and that randomness exists regardless of the depth of the bunker. For the lesser player, a shallow bunker can present the option of putting - which is a great way to get down in three but a difficult way to get down in two.
Jason,
I once lost a job (i.e. the minute I said it, the room went cold) by my answer to the question, "Mr. Brauer, don't you think it should be just as easy to reach a par 5 in 2 shots from the fw bunker as from the middle of the fairway?" My answer of "no" was apparently a shock to them, as was my follow up explanation that I usually make tee shot fw bunkers on par 5 holes deeper, figuring that even with a short iron out, they can still reach the green in 3, thus, there is no real penalty for hitting the bunker. Apparently, the penalty of "only" reaching a par 5 green in regulation figures was very real to those golfers.
Very few golfers I know think that putting out of a green side bunker is a viable way to play and avoid those.
As to the volcano bunker, I agree it is a problem in the wind. Plus, ancient sheep huddled in hollows, not on top of mounds to get out of the wind.
Speaking as a player, I will pay a fair amount of heed to fairway bunkers when I'm planning out how to play a hole, but on par fives, if they're not really deep, I basically ignore them. I figure I can lay up to them, but then I won't be able to get to the green in 2 and will have to lay up with my second shot also. If I take them on and miss them, then I might be able to get home in 2. If I take them on and hit them, then I'm most likely laying up unless they're very shallow. So there's not really any risk in taking them on.
That's a very different equation on a course where the bunkers are very deep. The specific hole I'm thinking of is 7 at Royal St. Georges. There are a couple of tiny little bunkers on the outside corner of the dogleg. They're about 200-220 from the green I think, so they're right where you might be hitting it if you're thinking of getting there. The lay of the land helps you get to them and also pushes the ball out towards them. If you go in them, your third shot is going to be from 180-200. 20 yards is as much as you can get out of them. They're virtually little penalty areas. RSG is littered with bunkers like that. If you lay back from bunkers like that, your gaining shots over the ones that go in there.
I actually think the sweet spot is somewhere in between the two extremes. There should be some penalty for going in them. A third shot from 160 instead of 80 perhaps. But some fairway bunkers you can't get home in 3 if you go in them. That seems a little harsh to me. Being able to go for the green virtually by right (it sounds like) is way too far the other way though. If you're good enough and brave (stupid) enough to hit a high cut with a long iron out of a relatively nasty bunker, then yes, you can get it on the green, but for all and sundry to be able to do it? What's the point of having the bunker at all?
