Today I am here with someone I am sure you guys are all familiar with, my friend, Mikey Musumeci.  Mikey is the most accomplished American Grappler of all time and has won the adult Black Belt Wolrds 2x.  No American has ever done this.  I just had him here for a seminar at my school and getting to know Mikey has been awesome.  He is not only extremely talented, he is very nice, and a Jiu Jitsu genius.  Check out this video with him below and then I do some breakdown.

Breakdown of How To Defend The Over Under Pass (Guard Retention) by Mikey Musumeci:

So guys as you can see Mikey is very technical with his approach to Jiu Jitsu.  This is a very simple escape to implement and it is more of a concept then a technique.  Mikey is turning on his side to face me so that he can put his knee on my shoulder.
After he is using the cross collar grip to push away my other shoulder and block the space where I want to put my   head.  This is very very important.  When Mikey is blocking both of my shoulders it is very difficult for me to put pressure, not only that but the way he does it he keeps his elbow closed and near his knee to block my head placement.
Guys this is a great way to defend the over under and I can tell you that it is very annoying when people do this to me.  I hope you guys enjoyed this, oss!
