The kumite that we practice is pretty much full contact until submission or knock out. The standing portion of the match reminds me of Kyokushinkai, but as soon as someone gets ahold of you it's very judoish. There is a time limit of 10 minutes, and if no one wins in that much time it goes to points. The way the points work is that there are 2 judges (usually a senior student and Sensei Whitsell), they stand on the sides and have a number clicker. Everytime they see aka make contact one of them clicks and gives the point and same with shiro. The match doesnt stop though when points are made, just keeps going. When it goes to the ground it's till submission. If times runs out the fight goes to who got the most hits before the fight went to the ground. If you knock your opponent out before you go to the ground then you win. Otherwise you have to make them submit. We haven't done much full speed kumite since I've been going, but a few weeks ago Doshu showed up and gave a demo of kumite with Sensei Whitsell. It was absolutely amazing, Doshu had him down and made him submit in about 20 seconds. A lot of the time when we do kumite it is in slow motion with Sensei Whitsell overtop of us giving direction, and asking us questions like if you stike this person with your left fist what do you have, or if you pull his sleeve here watch how he will roll off of you. All and all I have been very impressed with Saishu Ryu, and i'm happy I made the switch.
