The things I have read about this affliction suggest that the sufferer knows that putting is a simple task yet has a mind set that the consequences of failure are very serious. Consequently instead of concentrating on line and distance, he gets conscious of the movements he is about to make. Instead of making an automatic unified movement, the putt becomes a complicated issue of co-ordinating a series of separate movements.
The cure is to do whatever it takes to swing the putter on automatic. A set routine/ drill is one way, but do it without thinking. Another suggestions include thinking of something else during the putt, a complete change of putting method and thinking only of the line and target. The general concensus is that is a problem of the mind which requires a different mind set.
As someone who fights them with every type of putter there is, I believe this is the best explanation that I've ever heard put forth. It describes my mind-set exactly. They are very closely related to choking in my opinion. The more I "want" a putt, the worse it is.
I use what would be considered either a very "upright" Belly putter, or a "short" long putter. On longer putts, I will use the putter belly method. Shorter putts, where I feel I have no chance of coming within six inches of the hole using a standard technique/grip, I use the Long putter method.
I agree with the others as far as getting a set routine and trying to take the mind out of it as much as possible.
