2 Part Technique - Marcelo prefers not to submit with an arm-in Guillotine, but he will use this headlock position to pass an opponent's half guard on his right-hand side. Extend his body with the hold to make space by his hip, and climb out of his half by stepping on top of his knee with your free foot and sliding through. Since you don't have an underhook to establish the Side Control, avoid letting him turn onto his knees and apply Knee-On-Belly before releasing the headlock. If he grapevines around your leg in the half guard (whether laced inside in 10th Planet's Lockdown, or laced outside in a Reverse Lockdown), use your free foot to kick off his instep and immediately step through with the Knee Slide.
