Oops, is this hitting or swinging, I don't really sure but it works for me:
Left arm very relax, bring the club back 2 inches or more with the right arm folding, then back to the ball. #3 to sense distance. Control all on right arm
According to lagster, this is:
Hitting? since using right arm but I don't have any pushing motion, more a pitch position at address too.
Swinging? since left arm like a rope, but my motion with all control by the right arm and motion by the right arm.
