I have been training Luta Livre (see also: No-Gi BJJ) ~4 times a week for just over 5 months. Sounds like a short period of time, but I wrestled for just under 2 years, and have been interested in MMA/BJJ (mostly BJJ) for years, so it's safe to say I had a pretty damn good base. I was sitting with my instructor and one of the other regulars while everyone did the standard warmup (I was already warm) and my instructor was talking about promoting people. My name was brought up about being promoted to Yellow (equivalent to between white/blue in BJJ) and my instructor said I was ready but I'd have to show dominance over one of my peers. He (my peer) stinks like shit, spazzes, and I KNOW I'm better than he is (a brave statement, I know). When we roll, he goes all out, often attempting to bumrush me, so I'll pull guard. I've since decided that I'll just take top, because his defensive/guard game sucks. So instead of learning, I basically have to submit him in whatever fashion possible. The ONLY part of my game that I can't submit/sweep him from at will is my open guard/postured guard. He'll often just sit up and chill and as soon as I sit up to break his posture/hip bump sweep (I'm bad at it) he'll spazz. From their I'll fight for guard again or he'll escape to half guard, and again back to full, killing time, making it difficult to show my dominance. TLDR. If you're bored, throw some pointers on just about anything.
