Keeping your right hand on the grip in a neutral positoin allows the clubface to come into impact square, turning that hand in either direction will cause the face to close or open at the top of the backswing
Practice what a proper impact position should be lin the mirror and then go to the range and take small swings starting at your impact position
PGA Pros know the exact distance that they hit each club and you should as well, go out to the range when it is soft and hit each club in your bag squarly and mark each distance so you never select the wrong club again
