Defending the Brabo Choke

This morning I was looking through the blogs that I watch and after someone posted a youtube video of come cross-guard stuff, I ran across this. I will work on this. I tend to get to half guard and defend this choke by not allowing their whizzer. I should have no problem testing this reversal out for real… I w ill just let the whizzer get set and go.
