You're mistaken if you think that once you get to the mount, you only need to think about attacking. Of course, it's an offensive position that offers multiple different paths to the submission.

Try out the moves taught by Guillobel when you're warming up, repeating them over and over. Then employ them in your rolls, foiling your partners' escape attempts.
