SBG President and 5th Degree BJJ Black Belt Matt Thornton demonstrates here with Liam Thornton an underhook checklist that prevents the old school standing Americana lock that is often shown in Gracie Self Defence instruction. Helio Gracie has been pictured many times showing this submission. However, if you apply the underhook correctly by retracting it to your body, the Americana will not work. For anyone who wants to see the Old Americana applied, there was a video of grappling sparring between UFC Fighter Sean Strickland and Orlando Sanchez where Strickland became incensed with Sanchez fast application of the standing Americana.
