 If you can picture the whole golf swing, it's kind of like a circle, like this hula hoop. So where do I play the ball? Well, I'll brush the grass at the bottom of the circle. Let's have a look. Watch my club. You can see the brush of the grass happened at the bottom of the circle. So I will play the ball at the bottom of the circle where I brush the grass. That's for all the clubs on the ground. But when I'm playing a ball off of a tee and starting the hole, I'm going to play the ball ahead of center, toward the inside of your front foot. This is true on all the flat lines. But what happens when you're on an uneven line? This will be very helpful if you're a helper of a vet, because you may have to place the ball. So let's take a look. If you're going to have your veteran, I'm going to show on this uneven line, have your veteran take a practice swing. Notice for the condition, where do they brush the grass, and then have them play the ball there. It's pretty simple. A practice swing is pretty much required when you have an uneven line. Notice where the bottom of their swing is. Match that with the ball placement. I hope that helps.
