Good 2 Go was my escape from the mounted armbar (as opposed to the armbar from the guard). Essentially, it involved grabbing the gi, throwing off the leg that was over the face and rolling in the direction of the arm. Talking with Tommy Thursday night we both expressed a little hesitancy with that escape, mostly because you feel as if you are abandoning your arm—-always a jiu jitsu no-no.
Rodrigo showed us another escape that night, however, one that was similar in some ways to Good 2 Go, but one that resulted in a stack rather than a roll. Maybe I’ll call the old escape “Good 2 Roll”, because I think I like Rodrigo’s version better.
With Rodrigo’s escape, you also grab the collar to protect the arm. But instead of throwing off the leg, which can be difficult in some situations, you put your outside hand under the knee (crook of the knee) of the leg that is over your face or neck. This creates a block and gives you leverage as you drop step (bridge and inside leg drop) and turn into the armbar, going into a stack position.
From there you can use the Stack ‘n’ Jack escape to free your arm and then work to pass the legs.
