Yes.
Yes - assuming that's what this system entails. But I'd still like to hear from someone who's experienced the system?
I have no experience of the so-called system and I don't think the word system has any place in Tango.
But perhaps, and only perhaps, the teacher I have in mind has learned the Vin Diesel System (oops Dinzel I meant). Especially as he uses the same dreaded pedagogical words and he certainly is teaching a positive intervention (oh I meant active contribution of course) by the lady.
I'd be interested to hear from someone else too and also how it is the Dinzels know how tango was danced in this way in 1850 which almost certainly predates the embrace, upright posture, apilado etc. Is it just yet another teacher's version of tango adding even more confusion?
Just keep dancing - it's your tango, not theirs.
