Double under-hooks is the key to turning the half guard position into an offensive position. The ability to control your opponent becomes available once you have the double under-hooks and the Lockdown in place properly. The proximity to sweeping your opponent and getting to a top position is now just a step away.
However, achieving double under-hooks can be quite the battle in and of itself. Often, you opponent on top will be doing everything they can to secure one under-hook they need in order to pass your guard. If your opponent tries passing without an under-hook, you can simply take their back. The goal is to win the under-hook battle while using the legs to Lockdown and distract your opponent in order to help achieve this goal.

Step 2

Step 3
Grab you hands together and while continuing to stretch out the Lockdown.
Step 4
Grip your hands together using a Gable Grip. Wrap your fingers around the outside of your thumbs.
