De La Riva guard. A dying form that has recently been replaced by the "Leg Lock Era, but if you compete in the Gi you better know how the deal with it!! Personally, I don't play a lot of DLR, probably because I am a man, but I know a lot of guys that do, so here is a great breakdown of one of my favorite passes from DLR.
Pay close attention to the first step of pointing your knee to kill your opponents DLR hook, that really is the key. Also listen closely to my points of contact on the hip. Golden Rule for all guard passes!
