I noticed Hogan had a closed stance. I'm just curious about the geometric reasons for why this set-up produced a ton of good shots for me today. I don't think I was making any compensations....just taking it back insided and flat and trying to come down on the same plane.

Simply put, the Closed Stance with its automatic Short Pivot (10-12-B) produces a free Backstroke Turn (albeit with a restricted Follow-Through). This makes it easier to Clear the Right Hip in the Backstroke.

Failure to Clear the Right Hip during Start Up produces a Right Elbow-Right Hip conflict and is a problem epidemic in the Golf World. The Hands resolve this conflict without fanfare simply by going around the Hip. Unfortunately, that means you are now above Plane and must re-route the Club at some point to return correctly to the Ball. Most offenders never make it.

Hence, Homer included 'Clear Right Hip' as an important checkpoint in his Mechanical Checklist For All Strokes (12-3 #13).
