Brandon Mullins together with Stephen Kesting teaches his signature triangle choke from the half guard.
When your opponent underhooks your arm, you can enter the butterfly half-guard position or z-guard position, whizzer his arm and lock both hands together (often referred to as an arm-wrap).
From the same arm-wrap position, control your opponent’s far wrist, remove your butterfly hook and place your foot on his hip, and then shoot your other leg over his shoulder for a triangle. In this video, Stephan Kesting and Brandon Mullins show the same arm-wrap triangle, but from a z-guard.
