Was Jack a Hitter or Swinger or Switter..
 

Watched Jim McLeans special on Jack Nicklaus last night, as well as his players lesson on the the golf channel. It appears to me that he utilized an angled hinge, and had very left forearm turn on the backswing.He actually stated that he "tried to release the club from the top", however the pivot wouldn't let him. This would seem to indicate he was very aware of his right hand. Watching his motion, it appears there is a lot of right arm involved, although I wouldn't call it a pure hit. Maybe more of a switter...

Jack Nicklaus
 

/////////////////////////////////////////////////

I believe when Mr. Nicklaus was playing well he was mainly a SWINGER, utilizing DOWNSTROKE(FLOAT) LOADING. From hearing him talk, his CUES or FEELS for his motion would change from time to time. His RIGHT ELBOW gets into a position similar to the picture in 10-7-E, and worked beautifully in harmony with this Downstroke Loading technique.

Mr. Nicklaus was/is a good iron player, and a long, straight driver of the ball.

A swinging snapper, I guess.

Swinger, as he made no effort to "stifle and annul centrifugal force". It was centrifugal force that wouldn't let him "release the club from the top". His competitor, Mr. Palmer, was the Hitter. Longitudinal acceleration (pulling) versus Radial acceleration (pushing) is the key, not the hinge action.
