Sorry…I just saw this. I set up square-open not quite like Dianne in 10-3-E though! A couple things I have figured out about a push basic stroke.

Make sure you position your right elbow in a push basic fashion…it is a rather contrived feeling. My tendency is to inadvertently get into more of a punch elbow position (feels less contrived, I guess)
Initially I had distance control issues from close range (a common plight it seems!) I figured out that I was not taking advantage of the fact that the right push basic elbow is already primed for action given its bent status…on shorter putts I take the “pre-loaded” elbow back then go to both arms straight . Obviously for longer putts the club goes further up the plane i.e. more right elbow bend.
Push basic gets me closer to the ball, with a distinctly more upright plane.
ALWAYS go to both arms straight, or at least right arm straight…it don’t work otherwise!
