No drilling today, just rolling. Did a light roll with a newer classmate around my size, then paired up with a guy about 30lbs heavier than me and we went for subs for a good 10-15 min. I stayed on bottom the entire time, but I was able to control the fight and he spent most of his time in my guard defending sub attempts. I was able to get a guillotine, kimura, and another guillotine (off a faked kimura/sweep). By the end we were both pretty worn out, though I was happy that I was able to conserve energy pretty well and didn't try to match him muscle for muscle.
After a couple minutes of recovery, coach rolled with me to see how I'm progressing. He said I'm doing very well, but that I need to pay more attention to where I feel my opponent. At one point he made a move for my back and I had made space but ended up facing the other way; rather than recomposing my guard, I turtled and waited to see what he was going to do. He said I should be aware of when/where pressure is being applied, and if it's lifted I should make a move to get back to a better position, using my knowledge of where he was last if I'm not sure.
