Yes, great points. He takes a long calm eyed look at the hole just before he goes. He calls this "putting to the picture". He keeps this mental picture he has taken of the hole in mind during his stroke. Something his Dad taught him.

OK Now we're getting to the meat of the matter. Shoulder stroker or not? Im not sure about this. His shoulders can be seen moving, he doesnt extend his right arm actively which would suggest swinging, but he practices putting and chipping right hand only. His hands are quiet yes, his right hand bend is frozen. Perhaps he is somewhat blended? A right arm swinger? A hitter? A hands to pivot arc putting swinger with a down plane right shoulder move that takes a very structured RFFW into release? Or does he start down with his right arm only, his shoulders only reacting?

Any bigger brained TGM'ers want to offer an opinion as to whether he is swinging, hitting or switting his putts. I am fascinated by this. I personally find push basic to be a little stabby and pure shoulder strokes a little stiff. There must be some middle ground? Or is this a "blending aint mending" and therefore dangerous proposal?

Tiger has stated that he utilizes left-arm-only practice strokes as well, so focusing on his right-arm-only putting as a means to figure his method of powering his putting stroke may lead to misleading ideas about his stroke. I'd guess that it's a blend, leaning toward swinging.
