Broken Record

Yes, it's the shoulder in UH-GINN. To further improve the shoulder in, I must activate the inside hind, keep Delphi's hind and front legs crossing (tapping the shoulder with the whip and stepping rhythmically down into the inside stirrup helps this), keep her round and seeking the bit, keep a connected but not pulling outside rein, maintain just enough bend with the inside rein, allow her to sustain self carriage, and keep her moving "straight" along the three tracks of shoulder in. We can do this!

Video taken a year and a half ago; proof that Delphi can indeed perform shoulder in (if only to convince her owner!):
