Thought I would share this with everyone just  in case it could be of some help to someone else. For about 54 holes I have been having a problem pulling putts to the left. Not every putt, but on  enough putts to impact my score by about 3 or 4 strokes.  Normally I am a very consistent putter. Yesterday I decided to focus on my putting. Not really focusing on making more putts, but to see what the putter head was doing to casue these pulled putts. What I found was that on the back swing I was taking the putter head outside my target line, and then looping the club face back to the ball, and impacting the ball on the heel side of the putter face. I figured this out after 3 greens, and 8 putts. After I realized what I was doing, the next thing was to figure out why. Long story short. I had unknowingly changed my posture at address, and I was bent too far over, which gave me more of a bend in my elbows than I normally have. Once I straightened up a bit, which took the bend out of my elbows, I  started making more putts. Today I had 28 putts for 18 holes, and finished 7 over par. FHs
