On a normal swing I begin to uncock and then rolling when the right forearm is parallel to the ground.
When I focus on an aiming point in front of the ball, say for short irons, the dragging of the butt of the club down, down, down creates a much quicker sequence. Then without enough time for roll...there she goes....

if your implying a shank, I thinks thats what i'm having trouble with.
