Laura helps her with a walk with a lateral tendency.  They first find a rhythm that is best for her, and then use a shoulder fore. They work on the extended walk, bumping her with the leg when she snatches at the bridle.  Laura offers some sage advice on the importance of the walk scores in the tests. They allow the mare to struggle a bit as she sorts through the aids and the correct response, allowing her to learn through the process.  They teach her that positioning is not an aid and that they should be able to position her in whatever way is the most beneficial.
