My friend was apparently told at the IDB Dance Camp this past summer that in International Tango, the person going backward at least in the basic step doesn't do a toe release, because you shouldn't be pushing off of that foot, but pulling. She recounts to me how she was told by Anna Mikhed during a session that there is no pushing off the foot in Tango, only pulling, and that is why there is no toe release. Of course, I, being ignorant in Standard, was shocked to hear this, because I had always been told to do toe releases on power steps going backward. One time since I tried not doing toe releases, and the teacher (who was not my regular teacher) reminded me to do toe releases. I didn't say anything, and complied. Has anyone else heard this? Maybe you could explain this to me so I fully understand the concept, and let me know if this shows up in any other places. Thanks P.S. This is already at the third stage of the telephone game, Anna to my friend, my friend to me, and now me to you, so I'm sure there are details forgotten/skewed.
