2 Part Lesson -- Marcelo counters and escapes from 50/50: [I] If your opponent passes your foot with his hands from 50-Zero (Outside-Ashi, D.O.A., et al.) to the opposite side for the 50/50-Guard, keep your standing base and intercept both of his hands with your own to interrupt his control and regain proper footing. Try to pass you foot back to the other side where you can drop your knee heavily and hide your foot from attack. Swing your foot across his chest/face and bind up his head and arms to continue with a sprawling pass. [II] If your foot gets stuck halfway on the opponent's chest as you attempt to cross your foot out of the 50/50, press on the shins and free yourself from the knee-line; launch backward and kick your opponent off of your leg if necessary.
