The pinning techniques are classified in the order as shown below, you can glide from the first pinning technique (kesa gatame) into the next, right up to the 11th technique (Ura gatame) without interruption.
This means TORI can go from one technique into the other without loosing physical contact to lUKE. From the 12th pinning technique (Kashira gatame), it is more or less variants of the first 11 techniques, but with important differences in the execution.
