You say at the top of the backswing the left elbow is bent. Should the ball be sighted over the elbow or through the space between the elbow and the chest?
Whichever is comfortable. Snead, Hogan and Armour sight over the left elbow. I have tried both ways and find them equally efficacious.
Do you prefer the INSIDE-OUT or the OUTSIDE-IN?
These are merely two terms for the same thing. I advocate neither. Incidentally, you don't have to shout.
Should you ever choke the club?
I advise against it. What good does it do? Bend it over your shin and heave it down the course, or slam it against a tree. Regarding this last, I make use of the interlocking grip, with an open stance. The swing requires terrific concentration, since hitting a tree with your hands is one of the most unpleasant things that can happen to any golfer.
Could you list three simple rules for maintaining tension?
Yes. In fact I will list six: 1) Start your day by setting your alarm late. Bolt out of bed, shave with an old blade, then wake your wife and have words with her about not having coffee ready.
2) Race out of the house carrying your shoes in your hand. Then put them on in the car while stopping for red lights, perhaps causing other drivers to develop High Tension of their own. If possible, drive in traffic behind a car driven by a woman with a woman companion in the front seat.
3) Any time during the day that you feel tension easing off, pause and take a slow, deep breath with your eyes wide open. (Do you feel a kind of ache near the solar plexus?)
