"Latindiver. You are absolutely Correct.,when you say in CBMP the man doesn't turn his hip he only turns his shoulders to oppose his hip. You must, like me wonder how anybody can be having lessons and not know this.This is true."
Don, Don, Don.
It all depends on the direction of the rotation used to set up the CBMP (or more likley, the side lead that precedes it).
If it's a natural entry like an open impetus, the man will turn his shoulders to the lady while leaving his hip slightly open.
On the other hand, if it's a revers entry like an open telemark, the man will open his hip and foot to promenade, while leaving his shoulder closed to the lady.
