Unfortunately, common sense has little to do with the golf swing. I have written on several occasions that the swing is often opposite of what you think. One major flaw that most beginning golfers do during the swing is flip the right hand during impact in an effort to scoop the ball off the ground. The way you can determine if you are doing this deadly habit is if the club shaft and your left arm form an angle after impact. Take a slow practice swing and try to stop at the position just past where you would hit the ball. At this point, your left arm and the shaft of the club should be in a straight line. Also, if you rarely take a divot – and when you do, it's behind the ball and not out in front as it should be – then you are also guilty of the dreaded flip.
