This all begs the question, why is the golfer in the hazard (bunker) in the first place? The only reason the golfer should be in the hazard is by mistake! How many golfers aim to get in water hazards? IMHO, the same number should be aiming to get in bunker hazards.
Garland,
I think this thread started with you making a valid point and has progressed to where you're making unrealistic exaggerations. Sure it's possible to build an entirely penal golf course. That's not a very interesting GCA exercise, though.
In building an actual golf course, the idea is to give the architect as many different degrees of punitive features as possible.
It's a good thing when hitting the "wrong part" of a green costs you the chance at a makable birdie. That doesn't mean that it would be even better if being on the wrong side of the green means a five-putt.
It's also a good thing that bunkers exist so the architect can make missing the green by a couple yards on the bunker side worse than missing by a couple yards on the short grass side. But it doesn't mean that every greenside bunker should cost a full stroke.
It's a good thing that water hazards exist. They cost anywhere from a full stroke to even stroke and distance depending on how they're arranged.
But here's the really good thing. You can mix and match all of these on the same course or even the same hole. You can have a green with a ridge down the middle making the wrong side of the ridge into a difficult two-putt and the correct side of the ridge a makable birdie putt. On the very same hole you could put a bunker on the front left where missing there costs a good player a half-stroke and a weak player a full stroke or more. On the very same hole you could put water behind the green making any shot hit over the green cost a full stroke.
What you can't do is start from the arguably correct position that bunkers need not be
tooperfectly groomed and then immediately extend that to the idea that a bunker has to be as punitive as a water hazard. That's an nonsensical assertion that no decent player or decent architect is going to agree with. If they wanted a water hazard, they'd use a water hazard. Sand isn't just a cheaper form of water.
