If your grip is too weak (above), a natural motion for a right-handed golfer (where the back of your left hand is square to the target at impact) would return the clubface open, pointing way right of the target. To get the clubface square, you have to make some difficult compensations which could include - forcibly flipping the toe of the clubface over, an outside-to-in swing path and standing up, losing your posture through impact - to name a few.
