Gents:
I fear this is a question of how rigor in definition of the terms "strategic" and "penal" as well as the complexity of the strategy to be employed.
First of all.
JNC:
Your definition of penal hazard as compared to strategic hazard is messy, in my opinion. A hazard which has a penal nature (really deep, severally limiting options of play, etc.) is to be avoided at all costs. A hazard which is placed in a penal manner MUST be contended with to accomplish the hole (read: forced carry or hazards placed only to punish poor execution).
I do not agree with your definition of strategic hazard. It is a far too vague and does little to actually further the understanding of golf strategy in my opinion. I think you would agree that there are hazards in golf which A: influence strategy on the hole and B: would not offer any clear advantage to be near. An example of this is the road hole bunker on the 17th at the Old Course. If you want to say there are hazards in the game that influence the strategy of the hole by existing in locations where the golfer is attempting to play in order to gain an advantage for the next shot, then I would agree, but this is a subset of strategic hazards and not the categorical definition.
For me, a hazard is strategic if it's location is an influence on the strategy for the hole. A hazard is penal if it is placed in a manner which only punishes poor execution. It is in these definitions that I cannot see the bunker as a strategic hazard. If the bunker were taken away, the play would still be to the portion of the fairway where you and Joe hit your tee shots. Furthermore, if the bunker were taken away, the risk on the execution of this shot would be altered, however, this is only a tactical dilemma and does not change the fact that the portion of the fairway in which you located your tee shot is still the ideal position. The bunker is there to catch a mishit, it does not influence the ideal line taken from the tee.
Another way of putting it - did you place your tee shot in that spot because the bunker was there or because the geometry of the dogleg provided that was the most advantageous position within your range of skill for the next shot? I'll bet the bunker entered into the equation AFTER you considered the geometry of the hole, and not before.
Joe:
Both times I played the 18th at WW I was in the bunker after very poorly struck drives from the white tee, which according to my scorecard played 376. I remember hitting 6iron from 170 yards over the green on one occasion. In both instances, I was aiming to play over the bunker but not as near as possible to the bunker. What is the scale of the aerial comparison you showed? I also think the putting green is visible from the tee on the 18th at WW, no?
For me, from that yardage, the idea of strategy is almost non-existent and the hole becomes one of tactical execution. Executing a 230-250 yard tee shot into some part of the fairway inside the dogleg leaves an approach of under 150 yards from which another well-executed shot will hold the putting surface. The hazard inside the dogleg does little to influence the line of play outside of simply asking the golfer how much of the hazard can be carried and the hazards are placed to catch wayward shots.
