Really? That's interesting, man. Could you elaborate?
My first competition is coming up soon, and I wann go in there friendly, smiling, ready to roll hard, but I was also thinking I'm gonna have to be a bit meaner. Rolling, I don't cross face too hard, and I rarely dig elbows in or anything like that, but in a competition I assume that's par for the course-- things like the "rape" choke (can someone please give me a better name for that, really?), butterknife choke, etc.-- things I don't ordinarily do in rolling, I feel like those are definite.
Also, if I throw or sweep someone real hard, or they give some indication of an unusually painful thing occuring, I check and see if they're okay.
