Ok full disclosure. No one with an awkward or unusual putting stance has one because they were Good with the traditional stance. And no golfer playing with a guy with an awkward stance complains or invokes the rules of golf because the guys is missing putts. In my case I was not a good putter. My tendency was to pull everything to the left. I am right handed. I tried several different putters, stances, etc. Eventuality I discovered that if I placed left foot close to the ball but a few inches forward I can stroke the ball and follow through straight at the target. My left foot position prevents me from pulling the stroke across my body. The ball goes straight to the target. I am a much better putter from this stance, thus the complaints.
