Marcelo and Jimmy help Yuta with a problem regarding his opponent's ability to capture his leg while they're defending his Seat-Belt from the Turtle Position (Turtle-Guard, All-Fours, Quarter-Position, et al.). Hide your feet from your opponent/partner whenever you gain access to their Back; point your knees outward and drive the bottom one behind their arm to help facilitate a Crucifix entry. You can try to kick yourself free from the lock after rolling through, but you will need a tight Seat-Belt. Alternatively, you can find an Under-Hook and take Side Control if you are losing control over their Back. If your Seat-Belt is loose, don't roll over and follow your opponent's escape. Instead, stay on top and slide your knee through and away from their legs as you look for a way to stabilize your dominant top position.
