In this video I show a technical and easy way to clear the De la Riva hook when your opponent is cupping your ankle. This can be an absolute nightmare against someone who is good in Open Guard.
There are a number of great ways to deal with this hook and in this video I show my favorite. It starts off the same way as the Kick and Go pass. There is nothing more important than a stable base and good posture. This will set up all of the things that you want to do.
Once you have stabilized your base it's time to clear that cupping hand. You do this by turning the knee to the inside and doing a simple wrestler shot. It should be a quick movement that doesnt leave you exposed for very long.
After clearing the leg make sure you continue into whatever pass you prefer. In this video I couple it with the Kick and Go pass but it can be used to set up any number of passes. Just make sure you dont let your opponent regrip on your ankle!
