You can attack with this version of the Brabo Choke anytime your opponent is using his half guard from the bottom and is wearing a gi…
Marcio (dark gi) is caught in Marco’s (white gi) half guard. Marco is on his side with his left arm under Marcio’s armpit.
Marcio free’s Marco’s left lapel, stretching it behind his body…
and passes it to his right hand, under Marco’s neck.
Marcio now brings his right arm around Marco’s left arm and between their bodies…
… and grips the lapel that was stretched out earlier.
He grips the same lapel with his other hand and applies a nutcracker motion to the neck.
Marcio finalizes the choke by bringing his arms together and rocking his weight forward.
If Marco counters the choke by placing his hand on his own ear…
…then Marcio will pin that arm to the floor…
…and apply the choke using only one hand by driving his weight forward and down onto his opponent’s arm and shoulder.
