My trainer who is a hardcore BJJ guy, Braulio Estima black belt, has me doing a takedown technique where you go in with your head under your opponent's lead leg's shoulder while grabbing your opponent's lead leg above the knee to tip him over. You use your head to push your opponent forward and sideways. Your other hand is grabbing your opponent's back leg but not doing anything apart from that. You basically tip the guy over. The result should be your opponent looking like you just picked him up and slammed him. I asked him if this has technique has a name because I've seen it in MMA but he just calls it a double leg variant. I was asking because I can't figure out if this is more effective than just a simple double leg on the knees. If I go for the simple version I end up in mount or at worst guard, this takedown seems to land in side control at best. Flashy but effective?
