Copenhagen. It's in Denmark, where they make Legos. It's probably not be considered a hotbed of BJJ badasserry (don't tell Alexander Trans we said that). Still, grappling and BJJ are wholly international now and world class black belts are being developed all around the world. And, they travel around the world to compete as well. This past weekend, Braulio Estima took a short flight from Birmingham (England, not Alabama) to Copenhagen, Denmark for the apparent purpose of making all Danish black belts look like blue belts. And, he did it well. Enjoy the slaughter.
