In no-gi those are pretty much your main options. In the gi, you can use all manner of gi chokes that set up from north-south and finish on side control, many using your own gi. T-chokes are one that I use a lot. You can also set up darces from n-s with or without the gi by transitioning to n-s from side control and using your hip to force their arm across their face.
Would you say we're venturing into a ZONE OF DANGER?
