Start in your opponents open guard. They have the butterfly hooks and an under hook and are probably getting ready to sweep you.

1. Grab their knee on the opposite side as their underhook and push it down flat against the ground, locking your outstretched arm.

2. Grab the back of their gi with your underhooked arm as you step forward with your foot on that side. When you step, try to step a few inches past their knee on that side.

3. Slam your knee on that side down forcefully onto their leg just above the knee. You are trying to push that leg down to flatten it on top of the other pinned knee.

4. Once you’ve done this, quickly switch your grip so that you are gripping the knee of their top leg. Keep this arm outstretched.

5. Walk your legs around to end in side control on the underhooked side.
