Trying to Figure Out the Mikey Lock - Jiu-Jitsu

I have been trying to figure out Mikey Musumeci's Mikey Lock.

I haven't been able to work with my normal training partners.

I am hoping to get some work in on Saturday as I am going to my first Open Mat since the pandemic started.

Everyone is doing Gi so I hope I will be able to get some No Gi in.

This is one of the most innovative foot locks in a long time.
