3 Part Technique - Fold the opponent's legs if you notice their alignment is perpendicular. As the opponent pushes to reset, turn and twist inside against his posting hands to collapse his arms. Combine the principle of believing in one chance to execute the move with your effort in winning the position. Continue parrying and driving against the opponent's posting arms as you pass to establish Side Control. If the opponent transitions to Half Guard, continue pressuring through looking for a Control. As you find the Under Hook, use the control to force mount.
