This is an interesting point. Mindy talks about this in his detailed outline in gttb. I cannot see this flat wrist happening at address, the remark is made in "the takeaway" section, and it is my contention that the left hand is rounded after the first movement and not at address. If we look at fig 22 & 23 and fig 25 in tgsotf the back of the leading hand is cupped and not bowed. Feedback on this point will be welcome.
I was planning to go out and chip the other day, however the rain forced me indoors with my putter. After reading the sections on putting it became clear to me that Mindy regards the put as a miniture of the full shot with the movements minimised. I have been practice putting with the legs with some very good results. After i take the putter back with my hands, i pause and then by moving both knees in the direction of the pin i drag the putter through the ball. How many Midians out there put with their legs ?
I finaly started practising my chipping however it has been frustrating because of to many shanks. I am finally beginning to feel comfortable
with the grip completion, i must have had a mental block here.
I live on a golf estate with a nine hole "long par three course" and
practice by playing, practice is not allowed on the course.
