NEVER FORCE THE ISSUE
PUTTING is largely about touch. To really get a feel for speed, the stroke should be as easy, smooth and natural as I can make it. If I putt like a robot; stiff, locked up and too mechanical, I won't judge distance very well, especially on longer putts.
LET THE TOE PASS THE HEEL. If I keep my left arm fairly close to my side on the forward stroke, the putter-head will tend to rotate to the left after impact, the toe of the club passing the heel. I don't fight that natural tendency. The important thing is for the putterface to be square to the target line at impact, and that will hapen as long as my release is smooth and unhurried.
DON'T BLOCK IT DOWN THE LINE; some players are so desperate to avoid pushes and pulls that they shove the putterhead down the target line, keeping the clubface dead square from start to finish. It's a very unnatural action. It doesn't do much to provide square contact, and it's almost impossible to impart the right speed consistently.
