From 1rst degree BJJ black belt Gile Huni, editor of bjjee.com and instructor Kimura BJJ in Belgrade, Serbia:
“In this video I’m explaining 2 set ups to the half guard rollover sweep that I do very often in competition. There are about 5 more set ups but I’m keeping that for my students 
I usually speak in Serbian when I teach class but here it’s in English because we filmed the video for the net.”
