3 Part Technique - If your opponent is blocking every chance to win the position while hand-fighting him from his Butterfly, address the problem by obtaining control over his arm with 2on1 Control. Drag the 2on1 across to open up the space for an underhook as he tries to yank back his arm. If you beat one of his legs and force the half, bypass his arm and secure Underhook & Head Control for the Nogi Over/Under Pass vs Half Guard. If he uses a butterfly hook to prevent you from passing to the side, switch directions and quickly hop your leg over his butterfly hook into the Mount.
