Tripod Over Under Pressure Pass by Greg Hamilton BJJ

In considering the "Tripod Over Under Pressure Pass" presented in the video, it is worth exploring the historical development of pressure passing, specifically the over-under variant, and its roots in the evolving landscape of jiu-jitsu. While HoG Drama Desk accurately observes that this is a fundamental, and not necessarily a revelation in 2024, the emphasis on "pressure" has indeed been a consistent, if sometimes re-articulated, theme throughout the art's history, predating even the formalization of modern sport jiu-jitsu federations.

The over-under pass, by reputation, gained significant prominence in competitive jiu-jitsu around the late 1990s and early 2000s, coinciding with the increasing specialization of guard retention and passing strategies. Prior to this period, many passing methodologies often relied more on speed, agility, and dynamic movements, particularly as closed guard and spider guard defenses became more sophisticated. However, figures such as Carlson Gracie Sr., and later his students, including Murilo Bustamante and Mario Sperry, were known for emphasizing a heavy, top-pressure game, a philosophy that arguably laid the groundwork for the more systematic pressure passes seen today. While not exclusively an "over-under" focus, their approach necessitated an understanding of controlling an opponent's hips and maintaining a crushing posture, which are integral components of the pass under discussion.

The specific "over-under" configuration, involving one arm under the opponent's leg and the other over, driving into the hips or torso, became a staple for many competitors aiming to negate flexible and athletic guard players. I recall seeing this pass effectively utilized in early ADCC tournaments, which began in 1998, where the absence of the gi often necessitated different grips and positional controls, thereby highlighting the efficacy of body-to-body pressure and limb entanglement. The mechanical principles of leverage and weight distribution demonstrated in the video are, therefore, a refinement of techniques that have been iteratively developed and systematized over decades, rather than a singular invention. The "tripod" aspect, in particular, speaks to a contemporary understanding of base and balance that allows for sustained pressure and transitional control, building upon these older foundations.

To what extent do advancements in physical conditioning and sport-specific strength training, especially in the last 15 years, allow practitioners to apply these "fundamental" pressure passes with an intensity that might genuinely feel like a "game-changer" to those accustomed to different styles?

The tripod over-under pass really highlights the kuzushi aspect that's so central in judo. What Hamilton is doing with the leg configuration and the chest pressure is essentially breaking balance to one direction, which creates a window to advance. We call a lot of this tsukuri, the preparation for the technique. The video calls it "pressure," which is accurate, but the idea of constantly destabilizing the opponent is what makes the pass effective. I’ve been a judo shodan since 2004, and while the standing game is very different, the principles of off-balancing translate directly to passing. Still, my 19 years of judo didn't prevent me from getting smashed for the first 18 months of BJJ. It's a different animal on the ground.

I can definitely see what Kenji is talking about with the kuzushi. I feel that same kind of off-balancing when I'm trying this pass, especially when the person on the bottom keeps their hips really active. My coach, Dave, was drilling this with us last week, and he kept emphasizing how much the angle of our hips matters as we push into them. If I'm not careful, my top leg starts to lift too high, and then their hips just slide out and I'm back to square one. It's a fundamental for sure, but there are so many small details. I still can't hit it consistently on our purple belt, Alex. He always manages to recover guard.

The tripod over-under pass isn't something we see until the advanced curriculum at GB, usually in the second half of the 2-year cycle. Fundamentals focuses heavily on closed guard and mount escapes, things that are really basic. I get what Kenji (judo_to_bjj) means about kuzushi, but the way GB teaches passing, especially pressure passing like this, is more about creating frames and wedges to break posture and then slowly grinding your way through. It's less about a sudden off-balance and more about constant, heavy pressure. I remember specifically in the first year we spent a whole month just on maintaining cross-face and underhook control from side control.

I feel like most people miss the point of the tripod over-under and overemphasize the pressure part. If you're relying solely on pressure, a good guard player will just recompose, especially if they have strong hip escapes. We drill the specific entry from spider guard a lot at my academy. You break a grip, kick the leg through, and immediately go into the tripod. The speed of the entry is what makes the pass effective against people like Diego Lopes, not just leaning on them. Tom (gracie_barra_4yr) mentioned that it's an advanced curriculum move for them, which makes sense if they're not drilling entries that open it up.
