Has anyone here beatrn the yips ??
Archie,
If you truly have the yips, you can forget books, training aids, etc. With all due respect, the folks that are recommending those are talking about bad putting. The yips are another deal entirely. I'm 58 and have been yipping for about 7 yrs. I'm now in remission, but fully believe the saying "once you've had 'em, you've got 'em!"
I've used the belly, left hand low, claw, saw, looked at the hole, beer, and so on. The only thing that has worked for me long-term is the two-thumb or wishbone grip, which is a little more radical version of a super stroke big grip. It puts my wrists in a position where they can't break down, feels relatively natural, and is a pretty cheap experiment by comparison with some others.
I've been putting that way for a year and a half now, and it has made a dramatic difference. The cool thing about it is that when I have the feeling that I yipped, the ball still goes pretty much where I wanted it to go. That, in turn, has reduced the occurrences.
Good luck with whatever you try.
