@Julio Mejia the entire standing sequence was spent stuck in dueling collar ties. I suggest that you study that specific area with a focus on clearing the opponent's collar tie. The collar tie is a common position and you need to have deep knowledge and relationship to it. Study How to get to collar tie How I can use the collar tie (head shucks and snaps) How I can clear the collar Tues. Related topic includes overtie situations. On top. Learn a basic spiral ride and collect the wrists. The Peterson occurs because you allowed him to control your far side wrist during the transition. I suggest that you start by learning how that roll works and add it to you game so you can know how to avoid it.
@Julio Mejia don't leave your arms extended from the body. The Peterson is basically a grounded version of the sode throw from judo. The thing is no one is gonna be able to tell you how to do these things in text you need to get on the mat and tinkeraround and play with things. All we can really do on here is guide your attention toward areas to explore.
