Most people see the Mir Lock and the Americana as upper body submissions.

I see them as problems of angle and control.
In this variation, the finish isn't created by an overhook. The legs become the steering wheel. They control the angle, limit movement, and create the opening for the submission.

Small grip change. Different point of control. Same principle: understand the mechanics, and new opportunities appear.

How do you get to a leg attack from Shield Guard? At this point, the only limit is your creativity.

Most people think of Shield Guard as a way to create space, recover guard, or set up sweeps.
But once you start understanding the position, you realize it's connected to a lot more than that.

Here, I'm using the shield to create an angle, expose the leg, and enter directly into a leg attack.

The move itself isn't what interests me.
What interests me is how one position can create so many different opportunities.

That's why I've spent so much time studying Shield Guard. The deeper you go, the more creative you can become

Jiu-jitsu is a conversation.
I've said that for years. And the longer I teach, the more literally I mean it.

When you start, you're learning words. Moves. Vocabulary. But a handful of words isn't a conversation, you can know a hundred of them and still freeze, because you don't know how they connect, or how to answer when your partner speaks back.

The answers were never hidden in more technique. They were hidden in fluency, when you stop searching for the word and just speak. A sweep that leads to a pass. A pass that leads to the back. You're not remembering anymore. You're talking.

That's what I've spent decades teaching. Not more words. The language itself.

People asked for years when I'd make an instructional. I always said no, there's enough noise out there, and I didn't want to add to it. So I waited, until I had something worth your time.
It always had a home, my mat, my people. What it never had was a way out.

Today I built one. Not to add to the noise. To cut through it.

I’ve been obsessed with systems in Jiu-Jitsu for as long as I can remember.

Chaos is guaranteed in this art. Systems are what keep you in control.

I remember hearing an interview with Magnus Carlsen where he was asked how many moves ahead he can see in chess.

His answer surprised me.
To sum it up… he really can’t.
Not exactly.

At best, he’s making educated guesses based on patterns, experience, and what he’s seen thousands of times before. Even seeing just a few moves ahead becomes almost impossible when every position has so many possible responses.

Jiu-Jitsu is no different.

Too many reactions. Too many counters. Too many scrambles. Too many variables.

But every once in a while, if your understanding is deep enough, you can simplify it.

You can take something that feels like chess and turn it into a sweaty game of checkers. (no offense to checkers enthusiast)

You start removing options. Taking away space. Forcing predictable reactions. Leading the exchange somewhere familiar.

That’s where systems come from.

I’ve been pretty obsessed with thinking about and building systems for as long as I can remember. It’s not something new for me, it’s just how I was taught to see Jiu-Jitsu. And if you’ve ever been in one of my classes or seminars, you already know I lean heavily on teaching in sequences… small systems.

If I pass this way and he does that, then I do this.
If he doesn’t do that but instead does this, then I go here.

A simple 3-step guard passing sequence. A reliable path from side control to the back. A submission chain you can trust when things start moving fast.

Not random techniques.
Connected ideas.

The truth is building those systems takes years.
For me, with 30+ years on the mat, I didn’t even realize I was doing it while it was happening. I just kept returning to positions that made sense to me. Techniques that held up under pressure. Movements I trusted.

Over time the connections showed themselves.
And that may be one of the hardest parts of Jiu-Jitsu… not learning individual techniques, but learning how everything connects.

My knee cut is a good example.
I use a lot of passes, but most of them still revolve around the same footwork, same hand placement, same timing, same reactions that come off my knee cut.

Different entries. Different finishes.

Same language.

That’s the beauty of Jiu-Jitsu.

The longer you train, the less it becomes about knowing more moves.

And the more it becomes about building something connected enough that when things get chaotic… you still know exactly where you are.

You won’t predict everything.
But with a good system in place…
You may not have to.

Built for longevity. Not highlights.
The new site is almost here. In just a few weeks, RosendoDiazBJJ.com goes live, along with my first full instructional: a complete system built for real training, real bodies, and long-term progress.
No fluff. No highlight-reel nonsense. Just what works.
Shield Guard drops first. Quarter Guard is right behind it.
Stay ready.
