Ahhhh feels so good when you get it down right. Me and a friend enrolled in BJJ and today was our 10th or so class maybe. End of the class we get to free train for 10 minutes, 2 5 minute rounds. First round I roll with my normal training partner, who is about 25-30lbs heavier than me and the same height. I pull guard pretty soon, as I feel I work better from my back. Look for quite a few diff subs before finally isolating an arm and swinging a leg over to land the armbar. He rolls, ends up getting his feet under him a bit. But I manage to roll over on to my side, taking him down and he ends up tapping to the armbar. Almost got him in an X choke at the end of the time but he managed to escape. (although he did say there was a good 6-7 seconds where he couldnt breathe). Anyways, after that I rolled again with someone of about equal experience, but the guy had to have like 40-50 lbs on me. He landed an armbar and I instantly tapped becuase there was no escaping it. At the very end of the round I almost landed a north-south choke but the bell rang just as I was reaching with my left hand to grab my right wrist and really lock it down. Anyways, none of these submissions have actually been shown to me. I watched instructionals on youtube to see how to get a north-south choke and an armbar. (and a few others)And I have no idea how to even attempt to escape the armbar, like I said it hasnt even been introduced yet. (We have been shown an ankle lock, a kimura from the headlock, an x choke (is that what its called?) and the guilliotine) The rest has been different throws and escapes from basic clinches. So, any tips?
