Had Brazilian jiu-jitsu class last night. We got worked pretty hard - an amateur MMA fighter at the gym has a fight today and needed to cut some weight, so we had a more intense warm-up than usual and did a lot of drilling. As always, we did some live rolling near the end of class. We do 3 5-minute rounds, switching partners after each round. The first round was against a more experienced grappler. I took him down, but he was able sweep to mount, then took my back and worked for a choke, which I tapped to. We went again, and he took a shot. I sprawled and looked for a guillotine, but time ran out.
2nd round was against the MMA fighter. I've rolled with him before. He's pretty good. Needless to say, I spent the next 5 minutes trying to defend against various submission attempts. He eventually got me with a triangle/armbar combo.
3rd round was against a decent jiu-jitsu guy. I've rolled with him before, and the first submission I ever got on somebody was against him. The round started, and he tried to pull guard. He's very flexible, so he likes to work submissions from guard. I stayed out of his guard, though, and easily passed to side control. I got ahold of his arm, locked in an Americana and got the tap. He was a little frustrated with himself for giving it up easily. We went again, and he came at me like a madman. He tried for a guillotine before transitioning to my back and working for a choke. I defended against it for a while, and he then tried for a guillotine again. That gave me an opening to take him down. He started working a half-butterfly guard, but I passed it and locked in an arm triangle for the tap. We went again, and again he pulled guard. He started looking for a triangle, but I passed to side control and quickly locked in a kimura for the tap. This has been my best performance to date.
