Advanced Lesson Part 2 of 2 -- Marcelo emphasizes a point of precise pressure mid-pass: Training certain techniques in the gi can afford oneself with a much greater tolerance for mistakes in movement, whereas in nogi the margins for error tend to be quite smaller. Learning how to find the correct positioning with the gi on first can be helpful for hitting the mark later when faced with the less forgiving nogi scenario. This is particularly evident in the case of hitting a Back-Step from the Knee-Cut position; if your opponent is turned to much onto their side and hiding the far-side under-hook, finishing the Knee-Slide Pass may prove difficult. Force your opponent to switch and play from their opposite side by executing a swing backwards with your free-leg, but then intercept them with an under-hook before they can hide it from the reverse side as well. However, if your opponent tries to ride your momentum and come up on top with an under-hook of their own, you must be prepared to meet their advance with accuracy and balance in your base. Tuck your elbow in tightly to stifle their under-hook and place your chest and weight low against their turning profile. Sticking this position and landing onto the opposite side with the Back-Step becomes much harder to find when faced with the slipperiness of nogi; too high and you'll slide over, too low and you will be ineffectual in stopping them from turning over. Once you've maintained top control, pummel for an under-hook and finish the Back Step Pass as necessary.
