Set Ups: Against Butterfly Opponent Underhook

Entering the folding pass from Butterfly Guard when the opponent has an underhook involves maintaining a strong base to prevent being elevated.

1. Avoid driving forward when the opponent secures an underhook. Instead, focus on sagging the hips back and down to the mat, particularly rolling the right hip bone down.
2. By sagging the weight backwards, it becomes difficult for the opponent to lift. Aim to touch the hip flexor to the opponent's foot.
3. Make a grip on the seam of the opponent's pants while using the other hand on their collar or knee to maintain balance and control.
4. As the opponent attempts to lift, open the elbow, sag the weight, and shift shoulders towards the underhook to initiate a forearm clamp on the far side.
5. Chamber the left leg back to cover the space behind the opponent's knees, maintaining a grip on the elbow which can be used to forearm staple or transition to a C-grip.
6. Pass the guard by lining up head-to-head with the opponent, securing a four-fingers grip on the belt, and transitioning to the pass.
7. It's crucial to perform the sagging motion in response to the opponent's movement. If done preemptively without the opponent's attempt to lift, it can result in a stalemate.
8. Even if the opponent has an overhook on the arm, it's possible to use a forearm club by pulling the elbow shallow as they try to lift.
9. As the opponent lifts, set the position, pull the knee close to their hamstrings, glide to an ear-to-ear position, and complete the guard pass.
