How to deal with the turtle position

Ideally, if we side mount our opponent, we maintain good position, such that our opponent is rendered helpless and eventually we submit them. However, if the person is strong and/or we don't maintain strong control from the side mount, they may try to get to the turtle position as a way to escape. If they try to get to their knees in an attempt to go to the turtle position, immediately we need to sprawl to prevent the opponent from grabbing and controlling one of our legs. Once we sprawl, we can quickly control the opponent, spin around and obtain the back mount.
