Passing Half Butterfly Reverse Underhook

Passing the half butterfly guard when facing a flexible opponent who maintains a strong hook:

1. Recognize when the opponent's knee is compressed and the hook is strong, preventing you from pushing it down, across, or kicking through.
2. Capitalize on the opponent's flexibility which keeps their knee low, allowing for a potential mount that includes the hook.
3. Maintain control of your leg to keep the opponent's foot off the mat, then switch control from your arm to your leg.
4. When the opponent relaxes, shift your position and free your hand to win the nearside underhook.
5. Make a grip, switch your head to the opposite side, free your arm, and walk and lean to the opposite side, placing your forehead on the mat.
6. Align your shoulder line over or in line with the opponent's shoulders, with your head next to theirs, and use your free arm for base.
7. Control the opponent's connection to the mat with the turked leg to prevent bridging or hip escapes.
8. Avoid attempting to mount over the opponent's knee when it's pointed up as it can shift your balance.
9. Walk to bring the opponent's knee close to the mat, then push it down and step over to find a normal mount position.
10. During the pass, look for opportunities to rest and conserve energy while forcing the opponent to expend theirs, setting you up for better control and submission attempts post-pass.
