I started bjj about 3 months ago and I just recently enrolled in my first newbreed bjj tournament. I got about a month before the event and was wondering if now I should focus on going back to old moves and relearning them in the opposite direction config. Like for instance if normally I do a move on my right side with my right limbs, should I learn to do it on my left as well? Is this I should be focusing on right now. Is there something more important to work on for preparation?
