This is incorrect. Or overly simplified to the point that I am completely misunderstanding you.
I, for one, do not want my horse to seek a release from all contact. I want him to learn to accept, seek, and use the contact.
In the picture you’ve painted above of the horse carrying himself “in frame” with no contact, the horse is not properly trained to the contact. I’m at a loss for how you would ride such a beast, except on a completely loose rein.
And I certainly do not want to teach my horse anything before I teach him to engage his hind end, let alone anything to do with where to put his front end.
Side reins, used correctly, teach a horse to reach over his topline into the bridle. They teach acceptance of the contact. They have been used in this way going back into forever.[/QUOTE]
I’m not Nancy, but I don’t think she meant “release” in the way you’re thinking about it. I think she meant “release” in the way my dressage lessons tell me to release when the horse responds correctly–a softening of the hand, not a letting go of the reins, or of contact. As someone who struggles greatly with this concept (I tend to let go, rather than release!), side reins are one of the tools I’ve found helpful for letting the horse understand this, because IME the sliding/balancing/vienna type reins do allow this maintaining of contact while softening just a bit when the horse starts working into contact the way they should.
In theory, yes, a horse should carry itself correctly forward from behind whether there’s contact and a bridle there or not. Once they learn to carry themselves (something IMO sidereins, used properly, help with), they should carry themselves correctly when being worked, whether there is a contact or not. A hunter working properly, or a dressage horse doing a stretchy circle are still pushing from behind and through their backs.
