Do you want to know a little secret? Old School Passes are the best weapon against new school guards. When you have an opponent that likes to use more modern guard styles like lapel guard, worm guard, reverse de la Riva etc, you have to shut down these guards even before they happen. How? Put your knees on the mat, control the hips and put pressure!
One of the leaders of the new school guards, Keenan Cornelius (inventor of the worm guard) shows waht he considers the most basic but most powerful pass in Jiu-Jitsu: the double underhook pass (which eventually transitions to a single underhook pass)…
Alternatively, Saulo Ribeiro shows Budo Jake the Warrior’s Walk. This is different from the old school but in a way much more effective
This move is especially useful and practical when trying to pass the guard when you have a double under grip.
