For my game I find really deep bunkers to be very interesting hazards. If they are fairway bunkers, they provide a fearsome hazard and, a continuim of interesting recovery shots ranging from a pitch out backwards all the way to an attempt to hit the green. Greenside - they up the stakes for an aggressive iron shot while providing an opportunity for recovery with an excellent bunker shot.
However - I have watched many women in such bunkers and, unless they are very good players, they have absolutely no chance of getting out of them.
Should a designer ignore this issue? Do the advantages outweigh this disadvantage? Does the conclusion vary depending on the course? Can a course be all things to all people?
Should it attempt to be all things to all people?
If you're implying "dumbing it down to the lowest common denominator" NO
Nope - I am not. I am raising the question of whether the advantages of deep bunkers offset the disadvantages. I do not think the answer to that question is a clear answer.
The biggest advantage of deep green side bunkers is that they look cool or, as Joel's picture shows, required by the topography.
Other than that, I do not see much benefit to them. I disagree with any suggestion that they are significantly more difficult to play from than shallow green side bunkers for the competent bunker player. If you get the right thump, it really does not make a significant difference other than when you are short sided.
If you want bunkers to be fearsome hazards, just add some sand, or remove some, or use beach sand, stop watering them so they firm up, or design them so the player faces a bunch of sidehill and downhill lies. Such bunkers will give good players more fits than the manicured deep ones we see on many courses today.
Some of the posts on this thread seem to reject or dismiss the idea that some bunkers are so deep that they will result in an X for a significant portion of the female playing public. I have had many experiences of seeing someone go into a bunker and knowing they will never get out. Perhaps that is ok if it inspires improved play. From what I have seen it is more likely to inspire one to pick up the ball and throw it.
