Two of my favourites are on #7 at Pennard. First, they defend the ideal driving line for this drivable par 4 when the hole is front left (the tough position). Second, they defend the green. Third, the second bunker acts as a serious deterrent for those getting greedy trying to make a great recovery from the first bunker. Fourth, these are very penal bunkers just as bunkers should be. Finally, off the tee these are unobtrusive to the eye. The are tucked away so as not to disturb the views.
The bunkers as they appear from the tee.
A closer look. The flag is just visible over the left edge of the second bunker.
One day you lot will realize that I can use Pennard as an example of practically any great concept in golf design and this is partly why it is a great course.
Here is a bunker which I really admire because it must be dealt with on the 2nd shot. It comes into play in frontal wind and firm conditions. The bunker is larger than it appears from further back - great deception. It is also a lovely shape.
Here are two more examples. The bunkers really create two fairways. The safer left option which leaves a bad angle for a difficult approach. The more daring option right with oob to flirt with as well, but the angle of approach is much preferable.
Here is a devilish centreline bunker. In firm conditions it really is perplexing what to do - especially if you haven't hit a good drive which offers a view of the green. On the other hand, this bunker is reachable in the right conditions off the tee and it is blind over a hill. This bunker looks totally different than the ones at Pennard, but it functions in much the same way.
This centreline bunker is a totally different kettle of fish. It harasses the second for those who have mis-hit the drive or if there is a strong head wind.
I wish I had some good pix of Lederach. This course has to be the best example of centreline bunkering I have seen (if we take away TOC of course). KBM really put on a master class of using minimal bunkering to maximum effect. It seems there are loads more bunkers than there really are because nearly all of them are in the direct line of play.
