If you are using a push basic stroke.....practice straightening the right arm without the right wrist unbending. When I say practice it, I simply mean sit somewhere and practice bending and straightening the right arm without the right wrist unbending.

A spatial problem is probably the culprit of all yips....meaning the sighting systems of the body get confused and cause the hands to go places that you don't have control of. There is a field of study in this area and I am looking into it with a neuro-opthomologist.

I would stay away from "wild" concepts like a counter fall in the putting stroke. I find the only thing all that movement does is move low point around. I would also try different visual tricks, like looking at a spot in front of the ball, practicing with one eye closed, and practicing your hinge action with both eyes closed.
