Most Brazilian Jiu-Jitsu athletes and coaches would argue that the most dominant position in Jiu-Jitsu is the back control. And that, subsequently, the most dominant submission is the Rear Naked Choke… Except Roger Gracie.

Additionally, Roger explains that you’re pinned while mounted. Unlike when someone controls your back:

If you’re on my back, you cannot pin me. I cannot take you off my back, because first I have to defend my choke… But you have no control over my body.
So, that means that there is a lot of movement that I can try to use to escape.

In the Mount, there’s no movement. I am pinned down, I cannot move, and there’s no room between us that I can use to escape.

If you’re rolling against a skilled training partner or opponent, there’s a good chance that they’ll be able to escape positions you put them in – such as the Mount.
And sometimes, when someone skilled is escaping your Mount… It’s better that you bail out and get to Knee On Belly, rather than try and keep the position.

Matt Arroyo explains why and demonstrates how to bail out on the video below:
