Ball back in the stance
The ball placed back of center allows the hands to stay ahead of the club. Proper contact between the club face and the ball is the key to controlling the distance desired. This can only be achieved if the handle leads the club head at the point of impact. Without proper form feel cannot develop.
Having the weight of the body favoring the front leg encourages a descending blow on the ball rather than scooping it. If you are struggling with inconsistent contact, put more weight on the front leg and get ready for crisp chip shots.
