Everybody hits the ball with a slight movement one way or the other. What is important is hitting it the same most of the time. Also with a shape you have double the margin of error as with a straight shot.

This "double margin of error" stuff is often repeated but I just don't buy it. If you are hitting a 20 foot fade into the green and it doesn't fade, or you pull it a bit and it negates your fade, that's the exact same thing as a straight ball hitter hitting a 20 foot draw/pull. If your ball fades 40 feet instead of 20, or you add 20 feet of push to it, that's the same as the straight ball hitter hitting a 20 foot fade/push.
This whole logical fallacy is based on an assumption that if you are trying to work the ball in one direction your shot spread will be narrower than if you are playing it straight. There's no reason for this to be the case at all, though I can totally believe this is how it works in practice for those who have a natural shot shape and have to do something different in an attempt to hit a straight ball.
Technically, every shot may have some curve (even if only an inch) but if it doesn't curve enough to see the curve its the same thing as straight as far as where you choose to aim.
When I'm hitting the ball well, it goes straight as a string. Makes it easy to know where to aim. It's also easy to know where to aim to maximize my margin for error, because when I'm swinging well, my misses are always left (typically pulls rather than hooks) I really only ever miss right as a direct result of worries about missing left, so as long as I'm swinging well enough that I'm not really worried about a big miss left, I don't have to worry about what is on the right at all.
Now if you are actually trying to curve around an obstacle, and your ball will roll after landing, THEN working the ball is without question superior to playing a straight ball. And the greater the amount of roll the greater the relative benefit for working the ball. Thus working the ball is a lot more useful for our friends across the pond, but for those of us in the US, it is of little benefit on the courses most of us play. There's little point in trying to curve around a dogleg rather than just flying it if your ball is only going to roll 10 feet, ditto for trying to work an iron approach around a front bunker to a pin on the same side if the green is soft. (I guess I should add that if you hit the ball as high as I do, the percentage of courses where your drives only roll 10 feet or approach shots stick where they land will be far higher than they are for those playing a lower trajectory)
Yes, if I try to fly a dogleg and I mishit the shot I won't clear it and I'm in trouble, but that's no different than a guy trying to draw around it mishitting and having his draw crash into the trees on the corner. In such a circumstance, I think the odds of me coming out OK are better than the guy playing the draw, because his ball is coming into the trees at more of an angle, and thus if both of us managed to hit only leaves my ball has a better chance of getting a lucky break and coming out OK on the other side. On the other hand, my straight ball mishit on the green approach has a better chance of burying in the lip of the bunker than the other guy's mishit draw, so in reality it's probably a wash.
