I had the pleasure to train in a class with EBI Finalist Rafael Domingos at Drysdale Jiu Jitsu on 3/14/2018.
One of the things I enjoy about training with him is that he uses unorthodox techniques and is very smooth in his execution. In this class, he was teaching a position he called a single leg guard, but for me I remember it as a standing ashi garami.
He teaches a very simple sweep from here and follows it up with a cross step pass. Even this he does a little different than what I have seen, so I enjoyed learning this and have used it since with great results. Check it out:
