If you practice , and develope your own pre-shot routine, then take it on course, you will find that your shot accuracy will improve. All golfers want to practice towards a repeatable swing, and ball flight. It will not matter if your normal ball flight is a draw, straight, or fade. With a pre-shot routine, you will have an aim point, that will work in conjunction with your ball flight. A golfer can practice their own version of the pre-shot routine anywhere, with, or without a ball and club.

Here's what works for me. My normal, full swing ball flight is a slight fade to the right.  Knowning that, it would serve me no purpose to aim directly at my intended landing area. So, my aim point is left of the pin, or where I want the ball to land. I see alot of golfers continually aim directly straight from their ball to their intended target, then wonder why they landed in a hazard off to the side of that intended target.

My pre-shot routine: Check the condition of the lie I have. Check what obsticles might be in my way. Check distance to my landing target. Pull the club I need for the distance, and trejectory required. Then from about 10' behind the ball, I look at where I want the ball to land for the particular shot at hand. Now, knowing my ball is going fade, I pick a secondary target to the left of my primary target. I now line up the ball with that secondary target. Next I walk up towards the ball at at angle to left of my ball, while keeping my eyes on the seconday target. When I get along side of the ball I step into my stance, squaring everything up from my club face, feet, all the way up to my shoulders. When I am comfortable, it is swing time. Some of you might want to use a secondary target, which might be a spot just a foot or two in front of the ball. I do this for shorter shots.

This seems like it might be time consumming, but after a while it becomes automatic, and takes only about 15-20 seconds complete. The major rule is that while taking my stance, I never look at my primary target, focusing only on my secondary target. If I look at my primary target anytime befor my swing starts, I now would  have two targets in my head, which obviously causes me to make a poor swing. As for how much I should aim left, I use a simple painter's perspective. Let's say I need a 5 iron. For my swing, that would be the width of my thumb, pointing up, with an out stretched left  arm. The right edge of my thumb is next to my primary target, while the left edge of my thumb gives me my secondary target.  For my driver, it would be the width of my middle, and pointer fingers, pointing up, on an out left stretched arm.  

Sorry to so long winded, but it does work, and can be of help to most golfers.   Frog
