I spent 8 more minutes watching the first DVD. Given below is what I watched.
Kimura Defense From Opponent's Full Guard To Back Take To RNC. He uses the opponent's set up to get the kimura from full guard as a pass in this sequence. Instead of getting to side control, he goes one step further to take the back and then finish with the RNC.
Kimura Defense From Opponent's Full Guard To Reverse Kimura Within the Opponent's Full Guard. In this sequence, he blocks the opponent's set up for the kimura from full guard. Then, he weaves around with his arms to finish his opponent with the Reverse Kimura within this position, assuming the opponent doesn't remove from the full guard position.
Armbar from Opponent's Full Guard Mata Leao Defense to Double Leg Control To Side Control Transition. From this sequence, it's about stacking the opponent when the person is attacking the arm from full guard. Caio likes to get both legs to the full with a double leg control and then moves around on his tipping toes to get to side control. The arm bar defense is very common in BJJ, especially from heavier and bigger opponents. I like to do this move a lot when the opponents attempt this type of arm bar on me.
