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...
