First hit is to lock in your aim, second hit (when the diamond moves up the bar) is for power (hit at the far left for most distance, closer to the right for less) and third hit is like, how accurate it is? Like hitting the diamond makes it go where you want (not taking into account wind) then to the left will hit it more right and to the right will hit it more to the left.
I dunno much of anything about real golf and terms and all that. But if you want it to go as far as possible and hit your mark you want to stop the diamond in the diamond marks on the bar.
Thanks man, that is what I thought as I have never played a golf game before. Man I miss the days of manuals though...
