Great strategy isn't great strategy if the punishment for seeking the best next shot and erring slightly isn't severe. See post 15. If the "better" shot isn't threatened, then what choice is there?
On the other hand, it if is too severe, won't golfers just avoid it, negating strategy almost altogether? See my earlier post for an alternative view. All you really need is the possibility of losing a stroke, not the certainty of it. Probably encourages more risk, which is more fun.
I know most good players play very defensively, regardless of strategic theory of golden age architects. Maybe like football coaches, we tend to get more conservative over time, from hard experience, but hazard avoidance is pretty strong component of modern strategy, even given the occasional "get in the bunker" yell.
On any par 4, what is the strokes gained maximum potential of driving near a hazard? Given the 50-50% putting distance is about 6-10 feet at pro level, and maybe 4-6 feet at am level, and the standard proximity to pin is 10% of shot length at pro level and 15% at am level, (meaning no matter where they play from, they have only a marginally better chance of getting nearer the pin)
So what rational golfer will gamble on an average tenth to quarter stroke gained at the risk of a full stroke lost in a deep bunker where he has to play out backwards or sideways?
Or maybe, we just need to make sure how we define "severe." We might be talking the same thing and I might label it as moderate, who knows.
As has been oft discussed the trend to stroke play over match play has affected the ideals of the perfect strategic hazard. Any 2 stroke penalty type can ruin a round early. Obviously, par 5 holes are a chance to gain 1-2 strokes and can have harder hazards. And, place in the round may affect it. On later holes, all or nothing may make sense as you need it and have nothing to lose, save perhaps a few meaningless holes to finish should you plop it in the water or something.
Or the bigger question......has strategy evolved from where the old dead guys thought it would be? Equipment may have changed it. And, we can often ask the harder question - is there any real evidence that people played the coursed designed under those theories as they thought they did? Starting with the prize winning hole, do we know all of those 5 routes would have been taken more than once a blue moon, enough to justify building them?
Just throwing that out there for discussion.....
