Did my first warm-up ever, and apparently it was good enough in its purpose. Worked the classical sequence : jumping-jacks, squats, push-ups, crunches, side crunches, the three open guard motions and the neck warmup. Class was rather big, but hey, it was Monday.
Helped a few people with technique, to the best of my ability, but I stood within my circle of knowledge, refusing to wander out. When I didn't know the move, I stick to whatever we're told to teach.
Had a very enlightening black belt class : it was on passing the butterfly guard, taught by no other than prof. Bruno himself. That usually means it's the best advice we can possibly hope for with regard to butterfly. Surprisingly enough, he didn't emphasize running around the guard, or any funny movements, but rather controlling one or the other legs, from the inside or the outside, then either sprawling the weight + moving in a clock-like fashion, or a quick stopover.
Varied my rolls quite a bit. IN some, I insisted on playing open guard, others half-guard, others not breaking a single sweat. All in all I find it funny how little energy you really DO need to expend. Most of the time people fight for little things a bit too long, in sparring. Yeah, I have to pay for that with the occasional side control or mount, but if I can survive, all the better. I can better read the person's intentions by rolling this way. Also, I tried to go from spider to half back to spider quite a bit, in order to improve those transitions. There is a lot of work to do in that area, as far as I am concerned. Now I luckily also have the butterfly guard passes to play with as well.
All in all, good times.
