Ok so time for an update. Had a match the other day against one of the guys. Started off going for Osoto-gari, which didn't work. He faked a drop, and I sort of sprawled out. I got inside bicep control, after which he pushed forward. I attempted a sesei (sorry if spelling is wrong). Again, didn't work. He dropped and did a low single (yeah I have been doing my research kinda).
Now I pull guard. I pull an arm across. He attempts to stand up, and I pull a leg across his face going for armbar. He powers out (he is stronger than me, and has about 20 lbs on me). He slides around and I end up in half guard. From here, I attempt a sweep, and end up in guard again. He attempts to force a pass, and I end up sliding out and getting his back. Go for the choke, he throws me around. I catch an arm and pull an armbar from the back.
Of course, that was my only successful run so far. Thanks for all those who posted actual advice. And thank you, ryouboard, for being so encouraging to someone who is trying to learn.
