I recommend reading both Utley's and Pelz books. In my opinion Utley's style of putting is the way to go. But other than the actual stroke technique, I learned a lot from Pelz book about how to read greens and pre shot routine etc.

People are making sick comments about golf as a sport and the thread ends up getting locked. What have you done Tiger? There's now a war between hockey fans and golf fans.
Are you sure he just didn't repress his first tee shot so much that he forgot about it for a moment? I usually do that. I sometimes walk off a green and think to myself "yaaay birdie... oh wait... no it wasn't".
