I've been training less than a year and still feel like the new guy most of the time, but we've had some new people start lately, one brand new guy in particular I'm going to talk about. It was a normal class - we drilled some passes and passing defense, then when we rolled, I end up partnered with this new guy. I didn't get mad when he dug his elbows into my inner thighs to break my closed guard, but I immensely dislike that, and so I opened my guard and swept him to move on to something else. Later in the roll and after a weird scramble, he had a bit of a window and took my back like he was fighting for his life, which surprised me. This guy didn't have leg hooks in very good, but he went for a rear naked choke immediately, except his choking arm was across my chin / jaw. I tried turning my face toward his wrist (versus turning into the choke) to take some pressure off while grabbing his choking arm. I was going to try and clear the leg hook and walk myself around and into him (the main escape I know from here), and then I realize this guy has locked it up with both arms with all his strength like he is trying to crush my face. I felt like my face was being bear hugged from behind, but low and tight enough that I couldn't slip my head out. I don't know if he legit somehow thought he had the RNC in and was finishing it, or if he actually knew he was across my face and was just trying to use the pain / discomfort to make me tap. I lost focus on my escape attempt and ended up tapping versus try and fight his grip on my head, which makes me mad. Moving forward, I guess I'll have to be on my toes with this guy, but it seems like not giving him an inch when we roll or trying to shut him down doesn't make for a good mutual learning experience.
