I saw a rider schooling in a three-ring snaffle, but set up in a configuration I’ve never seen before. The cheek piece was attached to the large middle ring, and the reins to the bottom ring. The top ring was not attached to the bridle and pointed towards the horse’s nostrils in this setup.
Is there a specific reason for this option? It seems like it might have some gag action through the middle loose ring, but none of the leverage action.
