Budo Jake demonstrates a way to get a fast submission from the 50/50 position. He likes to quickly sweep or submit when in the 50/50, and this is one way you can end the match fast:
This choke is PURE EVIL! Not only do you have 4 possible submissions from the worst possible position… you also might just make your opponent cry! Hence the name…”Cry-Angle” Choke… triangle or Cry-angle…Either way it’s nasty!
