My friends above say it well, but let me try from another angle. It will all pretty much sound like repetition to one who knows already what we are saying - just another way of agreeing.
In 'the work' - real time or practice - I do not 'go for' a hip throw nor a sweep nor a shoulder throw....but instead, things' like this' can happen, depending more on every unique relationship of bodies moving in time and space. Not to say this does not happen 'automatically' to practitioners of throwing arts, particularly seasoned ones - its does!
Systema starts from a more free flow situational base, from the very start of ones education. Throws are more 'incidental' than deliberately sought. In a certain way, allowing them to just happen as a result of the 'moment shared' seems to permit an experienced Systemian to be 'free' to throw a body without the 'classically required' set ups that more technique oriented arts demonstrate at times.
Can an experienced practitioner 'make' a certain throw happen, for a certain reason...sure. It is usuallly intentionally done for demonstration of a certain type of throw - you break a balance in a certain way then can demo a throw.
But that is more a training tool - for only a 'free' Systema is a natural expression of the work. And naturalness is what we seek to attain, in movement and life as well.
We often use Vlad as the yardstick, for many reasons - besides his unbeliveable skill. Any experienced Systemist seems to be reluctant to ever say or post: "war stories". Mostly these become personally shared things amongst real time friends.
So we speak of our teacher and the things we witness..and I will mention such here...
ALL of Vlads people with a m.art background can easily recall some instance where "The Man" was doing free work...and then suddenly moved in such a manner to make an attacker FLY acroos the room in a move like 'XYZ'. Afterward, you migh say: "Vlad, I did not know you knew how to do Hiza Garuma or Ippon Seionage...where did you learn that?" His answer? Usually something like: "Is that what that is called? In what art?"
Basically, he never was taught either as a specific technique - he was just 'doing the work' and moving.
You can always tell when he does something that came out of nowhere - because of the look on his face that conveys a sense of "Oyee! Look at that!"...he sometimes seems more surprised than the onlookers. Sorta (in Bklynese) - "Ow, how did that guy toss his butt that way? Why did he do that?
This is not limited to Vlad, of course. Furtry here has done much like that to me, during a Toronto visit. Dumped me right on my back like a sack of wet cement...sorta modified ) O-Soto Gari. (HAD to modified, for if he tried the classical mode I was taught in my younger JJ days...I would not have gone anywhere and been able to (just maybe..MAYBE) deliver pressure to his leg for a take down myself. The point is - HE WAS NOT TRYING TO DO THIS! I hit the floor well enough...and at the last moment was able to lightly touch his foot as he was stepping forward in flow - and he went down also - more like a soft pillow than my cement sack...and I WAS NOT 'TRYING' TO DO THAT, either! Just caught his advancing foot just right, and I dont 'know' why I did it - it was natural and TOTALLY 'unforced' on my part.
Just an example, one Furtry probably does not even rememeber, for it was almost 3 years ago. I remember though, Dima, moy druk.
I know to someone from certain other arts that this sounds strange or impossible...maybe trite, to you.
Maybe not, depends upon the reader. Take it for whatever little it might be worth.
