I believe pedagogy is the right word... and it may indeed be an entirely new topic...
But if you go on the basis of those that purport that "Nuevo" does not mean a style, but a method of teaching. The basic idea (that I recall in classes I had with "Nuevo" teachers) is that it was broken down to the most basic idea that there are 3 steps (or positions) in tango that all others can be built from, a front cross, back cross and open step.
. . . . . . .
The relevance to this to the OC is that a front ocho ending and cross are the same thing (topologically) in that both of them leave the follows hips crossed to her partner if she were to leave her feet in place and try to turn. The main difference in whether a well trained follow takes one option versus the other being in how the leader is using his torso.
This is an apilado discussion and Neuvo analysis of the dance isn't relevant here. The nuevo group have a lot to answer for and even Chicho seems to be regretting some of what the group have done.
Ok, can't resist. To me Nuevo is mechanical and remote, apilado/milonguero is art and symbiotic co-operation.
And sticking with apilado and the OC, the rotating cross does not seem to require the partners' hips/pelvis to rotate away from facing each other.
End of conversation for me, I'm out of here. At least for the moment.
