Jack Nicklaus chose to fade the ball, left to right for a right handed player because it gave him more control & a wider margin for error. The reason being that the ball stops quicker than a draw, right to left for a right handed player. Hence the ball could land almost anywhere in the fairway & have a good chance of staying in it as opposed to a draw that lands & rolls & could roll through a fairway if it did not land with enough room for the roll out.
The reason one usually chooses a curving shot of one variety or the other is because it is easier to be consistent doing that as opposed to trying to hit the ball straight where it will move in either of an unknown direction when the execution of the straight ball is not hit properly.
Some people understand this thinking & some seem to not understand this thinking. It's easy to argue in text but totally another to do so in reality. There was a very talented Jr. Golfer that played golf with my son in the Jr. program who when at the top of his back swing could hit whatever one called out, fade or draw & even high or low if you added that, such as high draw or low fade, etc., but... he could not hit it straight without the ball tailing to one side or the other when ever he wanted to do so. Sometimes it would go straight but most time is would tail off in one direction or the other & he never knew which until after he had hit it.
One might argue that missing the exact intended target has the same margin for error & they might be correct but the difference is that when one has a plan for a certain type curved shot they also implement a plan for that shape shot & adjust their initial target to take the plan into consideration. The two together yield an effective increase of the margin for error for the final outcome but not the chance of failure to execute perfectly.
Some understand this & some seem to not.
I have very rarely ever gone long of a spot when I tried to be short of the spot & vise versa. But... when I have had to go for an exact spot, I have been short & long when I did not hit it exactly.
