For success, this technique requires distance between Lucie and her opponent and to crush their posture on entry.
This combination was developed as a result of opponents expecting Décosse's Ouchi gari.
As opponents reached over the top with the right hand, Lucie would force her left hand into their shoulder, pulling on the sleeve and stabbing at their lead leg.
In this variation, Décosse catches the opponents right arm before they grip moving it across they're body and closing the space to attack.
