I am 63 and have dealt with the yips for 20 years. Tried many different putters, stances, dots on the club handle, closing the
eyes, looking at the hole, belly putter etc. A friend's instructor showed him this and he passed it along to me. For a while
I forgot about it, and then in the middle of one really nasty yipping round, I said what the heck and that was 4 months ago and it
has worked like a charm ever since. Give it a real try if you yip and let me know what you think!
