You got it! Over the top chop. It's hard to fight the "hit down on it" impulse with the hands and arms.

Bob, I took a few lessons from you at Country Club of Miami where I was a caddy at about age 15. I recall carrying your bag to the first tee for a clinic attended by at least 100 persons. You were asked by a woman why you did not become a jockey, to which you replied, " Mam, I do all my riding at home." Are there transcriptions of your utube videos? I distinctly remember you saying " feel the force, not force the feel." Even with modern filming technology, it is very difficult to establish what comes first on the down swing. Without a doubt, the over the top chop is a swing fault of most players who should be bowling. Good eye/ hand coordination and the capacity to visualize a shot direction and trajectory seem to be the key elements. While teaching a great wide receiver, Hall of Fame, he asked when to uncock his hands in the downswing. I replied " when do actually reach out to catch a pass." Hope you are well!

Agree. My dad, born in 1911, give me one instruction which was to swing the club back and forth and get out of the way!
