3 Part Technique - Grabbing your opponent with Collar & Elbow Control against his Butterfly is a bit of a Goldilocks Problem: Grabbing from too far away prevents him from gaining underhooks but weakens your control. Grabbing it too close gives a strong control but offers him his underhooks. Find the middle ground between the two distances and steer him onto his side for the Folding Pass with Double Under Control. If his knee is out of range for the fold, block his hip-line with your arm and either cut your knee through with a Knee Slide or just simply walk around with the Circle Pass.
