Patrick,
I have heard that argument about improving your lie by grounding your club and I never remember to try it when I am playing just to see how much I can improve my lie in a bunker by grounding my club. My thought has always been that to make a significant improvement in one's lie by grounding you certainly run the risk of causing the ball to move. I just think the creative design options for bunkering are better if some people were less concerned about this rule.
Lou,
I don't think a bunker that does not allow you to advance the ball all the way to the green is one dimensional and reduces your options. For a minute please disregard your statement about a bunker that only allows a wedge shot back into the fairway, that is not a correct interpretation of what I was saying. If for instance the distance to the green is a 5 iron but the bunker at best will allow you no more than a 7 iron shot or less, then the design of the green angle and the elements in front of you should be interesting enough to have you weigh the options that range between a SW and a 7 iron and at what angle do you prefer to enter the green on the next shot, at what distance would you like to be because of the green design and to what level of risk are you willing to go to meet the angle, lie, distance etc. in order to leave yourself with the best possible next shot. That to me introduces much thought about strategy and does promote excitement in recovery shots. I totally agree that one of the most exciting elements of golf is when one is faced with a recovery shot and much can be said about the quality of a player based upon their ability to adjust to adversity and respond in the proer way, not always heroic but certainly that is one way, but smart as well. Furthermore back at the tee if the fairway bunker is as you described in your original post, shallow, low lip toward the green side, then I think you have severely diminished the quality of the options or choices that face you on the tee. So options from the bunker begin with the options that are presented at the tee, and the natural elements that are infused into the design help scramble any feeling that there is rigidity in the design, that a template hole has been presented as opposed to a hole that someone obviously discovered on the land and pondered for many hours or days while walking it back and forth. Earlier we got into a discussion about how computers have helped design and I think some questioned the importance of these instruments, and one architect said well if you disregard computers in design then that is your loss. Now go and read the Links article about Coore Crenshaw and Bandon Trails and their methodology for design which I will just boil down simply to being in the field and grinding out the design, now what architect worth their salt wouldn't want to conduct their business in that manner, how many would still say you know what give me my computer and a few site visits as opoosed to constant immersion in the field day in day out grinding out the design walking the land, now who looks outdated in their approach to design, the guy with the advanced computer, and the various software packages that can read everything and spit out intricate information about the land or the guy in the field, no computer, just two legs, and an observant seraching mind. of those two architects who represents the future and who is outdated? so in the field design in the field spotting and cutting out of bunkers will not always yield the bunker that allows you to advance the ball to the green but it will allow you to stand in that bunker walk out of that bunker judge the type of clubs that can extract a ball, how far each shot will go where they will land what is there where they will land how that sizes up with the approach into the green and so forth. Much less of a template approach as compared to what I thought you were saying in you original post. But obiviously you have found much information in your study of MacKenzie and I see no need for you to look further and even consider anything I have to say on the subject. You have found the ark of the covenent in MacKenzie. Enjoy.
