I think and I could be wrong. But the last lesson I had, we did a bit/drill where the club face controlled the ball spin. Leaving the face open made the ball fade. Hitting with the club face square hit the ball straight. Hitting the ball by crossing the hands over caused it to draw. This lessson was not about smashing it down the range but hitting it 50 ish yards and seeing what the club face did to the ball.I couldn't even work out what he meant to do let alone do it. I got lost at the bit where he had his hands crossed over - last person I saw playing golf like that was off about 26! I'm just not a technical golf swing person I guess. Just swing my swing and some days it works better than others.
