In Jiu Jitsu, knowing the rules can be the difference between winning and losing a close match. But rules affect more than scores — they shape how athletes train, how referees make decisions, and what kind of sport fans get to watch.
I sat down with Carl — referee, coach, and longtime competitor — to talk about what he's learned from years on the mat and at major tournaments. His message was straightforward: if you compete, understanding the rules is part of being prepared.
A Referee's Best Work Often Goes Unnoticed
Refereeing a major tournament brings pressure from several directions. Organizers trust referees to make sound calls, while athletes have months of training and a tournament result riding on those decisions.
Carl told me his ideal outcome as a referee is simple: competitors forget he was even there. The athletes and the match should be what people remember — not a controversial call.
That responsibility applies at smaller events too, he said. A competitor's investment in a local tournament still matters, whether it's their first event or their hundredth. Consistent, careful officiating helps protect the experience at every level.
Rules Are Part of Your Competitive Skill Set
Carl told me that many athletes enter tournaments without fully understanding what's legal, how scoring works, or which positions earn an advantage. That can be costly, especially in close matches where a small scoring detail decides the outcome.
He shared a story about winning a match by recognizing an advantage opportunity from half guard with a crossface. Knowing the rule let him make a purposeful choice — not knowing it could have meant missing the opportunity entirely.
I asked him why competitors overlook the rules so often. A few reasons stood out:
- Different organizations use different rule sets. Athletes may assume what applies at one event applies everywhere.
- Rule resources can be easy to miss. Some competitors simply don't know where to find explanations.
- Rules change. Knowledge from years ago may no longer reflect the current rules.
Before an event, Carl's advice is to check the specific rule set and make time to understand how it handles scoring, penalties, and prohibited techniques. Rules aren't just for referees — they're part of the competition you're entering.
Clear Rules Can Support Better Matches
We also got into whether a shorter, looser rule set makes Jiu Jitsu more creative or entertaining. Carl's view: fewer rules don't necessarily lead to more action. If standards for activity and stalling are unclear, athletes may have little incentive to take risks.
At the highest level, he said, competitors are skilled at finding the limits of a rule set. Clear criteria help athletes and referees understand what's expected, and make decisions more consistent.
Different events may reasonably choose different rules, but Carl made the point that it helps to be clear about the goal: a large tournament has to run fairly and efficiently across many matches, while a spectator-focused event may prioritize a different experience. The format influences what kinds of rules make sense.
Train With Purpose, Not Just Variety
Carl's advice for getting better applies whether you compete or train for fun: pick a direction and stick with it long enough to learn.
If you regularly get stuck in mount, work on mount escapes. If you want to develop a new guard, commit to practicing it for more than a day or two. If a technique doesn't work right away, that doesn't automatically mean it's wrong for you.
Improvement often comes from repetition — drilling, testing a technique, noticing where it breaks down, and trying again. That process can feel less exciting than constantly chasing something new, but it's how movements become reliable.
The right balance depends on your goals, Carl told me. A competitor preparing for an event may benefit from a focused training block. Someone training mainly for enjoyment may choose to experiment more. The important thing is training in a way that matches what you actually want from the sport.
Jiu Jitsu Is Evolving — and So Are Its Athletes
Carl started training in 2009, when access to instruction and competition footage was a lot more limited than it is now. Today, athletes can learn from far more material, and the sport is developing quickly. That wider access is valuable, he said, but it also means the standard of competition keeps rising.
Rules and competition structures influence more than tournament day — they shape which techniques athletes practice and what coaches emphasize. Even people who don't compete feel those effects in the gym.
That creates an added challenge for coaches like us: students have different bodies, goals, and learning styles. A technique that works well for one person may not suit another. Carl's approach is to teach options while staying open-minded, and to focus on principles that transfer across techniques — something I try to do myself.
Understanding the rules won't guarantee a win, but it gives you more control over how you compete.
Key Takeaways from My Conversation with Carl
- Review the rules for the specific event you're entering.
- Keep your knowledge current — don't rely on rules you learned years ago.
- Learn how scoring and penalties work, not only which techniques are legal.
- Choose a skill or weakness to work on and give it time.
- Match your training approach to your goals — competition, improvement, enjoyment, or a mix.
- As a coach, offer adaptable options rather than assuming one technique fits everyone.
Understanding the rules won't guarantee a win, and focused training doesn't have to mean making every session feel like work. But both give you more control over how you compete and improve — and help you understand the sport as it continues to grow.
