Hi, after I get someone's arm extended in side mount, how can I put a side choke on them ? -- the choke where you push your chin against their arm/tricep. I know I can slap on a keylock or whatever, but I'd much prefer to choke someone out in the street rather than dislocate their shoulder. Btw, does anyone else find they get someone's arm extended after they've got them in side control ? I notice the more experienced guy are easily able to do it.
