I´ve practiced o soto gari now for a while the way it is regularly taught in judo clubs here. High grip (left-handed), step parallel, pull his elbow out, chest to chest contact, trying to bring ukes weight on the foot I am about to do the throw on.
However I have not really been able to to do the throw like this in sparring. I have also never seen it done in competition like this. Usually there is no step and offbalancing but rather a sort of a kick type motion with the throwing foot and then hopping on the other leg and driving through at the same time. Is that the more efficient version of o soto gari? Any pointers how to practice this variation?
