How To Do A Hook Sweep Sacrifice Throw like Erberth Santos. Gile Huni, editor of http://www.bjjee.com/ teaches the technique in Serbian but has put English subtitles. “This is a simple throw that I’ve been doing since blue belt. Anybody can do this. Important points is that your opponent has to push into you. You need to fall to the side, hook underneath the knee and other leg scissoring for a sweep. Your arms need to stay extended. If you fall straight down it will not work.”
