Dan Kelly,
Intimidation is usually a product of recognition.
Confusion is often the product of an inability to recognize.
I trust that you understand the distinction.
ChrisB,
I don't have the vision to determine the condition of a bunker at 225 to 275 yards, so that's almost never a factor.
The narrowness found in trench and pot bunkers would be a factor, but these bunkers are so rare that we don't usually come into contact with them, let alone see them from 225 to 275 yards.
Plugging is usually a function of flight/trajectory and I must admit that I've never given that consequence any thought while standing on a tee.
The perception that the configuration of the bunker will substantially act to impede the flight of my recovery shot seems to be the overwhelming consideration, and that almost always translates to depth, or face wall height.
Ian Andrew,
The 6th at PV presents a collage of bunkers mixed with other unpleasant features, at assorted depths, certainly an intimidating sight off the tee, one that is best avoided.
I wonder, with today's distances, if this feature hasn't been circumvented, like the maginot line.
