thinking2 means by weak grip as not enough knuckles showing on the left hand. when you grip the club, you shoulg see two to three knuckles showing. a medium loose grip is good. what's happening is that the club head is going from right to left, but the face is open.that why on your irons, the divot is going left, but ball goes right. do as thinking2 and buns said at the range, if that doesn't help, do the jim furyk swing by taking the club straight back from the ball, when you get to top of the swing, let the club drop down so that it comes from the inside. practice this without a ball first. this is only to get you to feel what it's like to come from the inside. it will seem like your going to hit the ball to the right, but you won't. another tip to help you square the club face is to let your left arm slow down a little so that your right hand flips over top of it right before you hit the ball. ball placement: irons in the middle of stance , driver towards left foot.
