Draw the right knee back, left knee forward at the top
Craig Hanson describes a symmetrical knee move at the top of the backswing: the amount the right knee draws back is matched by the left knee moving forward. He says this can increase turn and tilt and prevent early extension, and that it drops the left hip to give room to tilt and turn.
