My many faces

One of the biggest and most debated topics in the BJJ community is the turtle position. There are two big arguements about this position. 1) Is it an actual guard? 2) If it gets used as a guard how do we score it in tournaments? In my opinion for a position to be considered a guard, it must fit three requirements: 1) It must start from a defensive standpoint. 2) You must be able to defend yourself AND launch attack. 3) It must have at least one(1) self-defense application. 4) You must have a way to control your opponent/enemy. So let's see if turtle is a legitimate guard. On your knees not being able to see your enemy sounds pretty defensive to me. Your hands and elbows can keep you from taking punches and knees flush and you have access to kneebars, toeholds, kimuras, armbars, wristlocks and a boatload of sweeps. So that's points one and two covered. On to point 3 and 4 Self-defense application: When you turtle on the street you roll away immediately and sit to full guard or
