Matthew,
You need to get over the ruling concept of "par". Par is irrelevant, changing the par doesn't change the hole.
A "hazard you need to avoid" is one you'd play away from. A hazard you "take on" is one which delivers a benefit from successfully playing near to it.
You have to engage with the creek on 13 at ANGC to have the best chance of success (birdie or eagle) on the hole. If you avoid engaging with it and play wide off the tee, or lay up short of it with your approach, you'll be safer but less likely to make better than par.
Great courses are full of holes with hazards you have to "take on".
The point I am making with #13 at ANGC is if it were a "par 4," WHICH HAS NO EFFECT ON THE ARCHITECTURE, (I have underdstood that from day one on the site) changes the psychology of the player playing the hole. But let me go back to the real issue.....
The TRUE POINT I am trying to get to is in order to access the back left hole location they had today, you have to "take on" the creek like Rose did.
Because the creek is parallel to the fairway, it might seem like you "play away from it" but you still challenge the creek side of the fairway. If you think "play away from it" then you are looking at glass half empty. That is a negative way of looking at the creek and just messes with your mental state. Rose had the mind of a champion: took on the creek side of the fairway in order to have a good angle into today's hole location. What did he get out of it? A BIRDIE. And the result on that one hole helped him get into a playoff.
HERE IS THE MOST IMPORTANT PART: I DO
NOT LIKE THE HOLE. SOMETHING BETTER COULD HAVE COME FROM THAT LAND..... BUT THE CURRENT HOLE, AS MUCH AS I HAVE A HARD TIME SAYING AND OTHERS DON'T BELIEVE, HAS
SOME STRATEGIC VALUE.
