Turn your torso, don't fake it with your shoulder

This exposes a fake turn: you can move the shoulder so it looks like you've gone 'behind the ball' while the torso hasn't actually rotated - put the shoulder back in its socket and it reveals you never turned. The fix is to keep the shoulder in its socket and turn the torso, and the cue is to feel the right shoulder blade drawing 'against the back,' which makes the torso turn.
