The sport's most feared guard passer also built a system for not being passed. Codified in his no-gi instructional They Shall Not Pass, Gordon Ryan's retention game is organized around his own loose-versus-tight passing taxonomy and taught through live gym footage — the defensive mirror image of the passing game that made his name.
The strange thing about the most feared guard passer of his generation releasing a guard-retention instructional is that it is not strange at all. It is the same knowledge, read from the other side of the exchange.
The centerpiece of Gordon Ryan's They Shall Not Pass is not a lecture. It is footage: Ryan on his back in a training room, letting a rotation of partners try to pass his guard, and then narrating the tape afterward — freezing the frame, naming the pass that was coming, and explaining the small early adjustment that killed it before it launched. There is no highlight-reel finish at the end, because retention has no finish. The evidence that the system worked is an absence: a pass that never arrived, a chest connection the passer never got, a scoring position that never appeared on the clock.
That inversion is the whole premise. Ryan spent years reducing guard passing to a solvable sequence — loose passing to force a reaction, tight passing to cash it in — and won the sport's biggest no-gi titles doing it. The retention system is that same map turned around. If a passer's whole plan is to make the bottom player commit early with a loose pass and then bury him with a tight one, then the defender's whole plan is to refuse the reaction and deny the connection. Ryan knows exactly what the passer is trying to do at each stage, because at each stage he is the passer everyone else is trying to solve.
This is not a story about how Gordon Ryan attacks. It is a story about how the man who passes everyone's guard taught the rest of the room to keep theirs — and why his version of that lesson looks nothing like anyone else's.
Gordon Ryan's guard retention is the passing game read backwards: a no-gi system organized around his own loose-versus-tight taxonomy, in which the defender's only job is to refuse the reaction a loose pass wants and deny the connection a tight pass needs.
Gordon Ryan came up in the New Jersey grappling scene under Tom DeBlass before moving to the coach who would define his career, John Danaher, at the Renzo Gracie Academy in Manhattan. He received his black belt in February 2016 and became the most visible competitor in the group known as the Danaher Death Squad, later relocating with Danaher to found New Wave Jiu-Jitsu in Austin, Texas, the school rebranded Kingsway Jiu-Jitsu in 2025. The full competitive record is treated in his athlete profile; the short version is that he is a seven-time ADCC champion and, by that record, the most accomplished no-gi grappler of his era.
Retention is not the part of that record the public remembers. Ryan's name is attached to leg locks, systematic passing, and back attacks — the offense. But the retention material has a specific and traceable origin, and it is not a separate project bolted onto the game. It is the same game, inverted.
Its parent is Ryan's passing system, codified in his Systematically Attacking the Guard instructionals, which organize all of guard passing around a single distinction: loose passing and tight passing. Loose passing — the toreando (bullfighter) and its standing, distance-based cousins — is used to make the bottom player react, to pull a leg or a frame out of position. Tight passing — the knee cut, the stack, the body lock, chest-to-chest pressure — is used to consolidate and finish the pass once that reaction has opened a seam. Ryan's whole passing method is the marriage of the two: force the reaction loose, cash it in tight.
They Shall Not Pass, released through BJJ Fanatics in 2021, is the retention system built from that same distinction. Across eight volumes it teaches guard retention explicitly as the answer to loose and to tight passing in turn — "how the bottom person should react to both," in the instructional's own framing — rather than as a catalog of counters indexed to particular guards. The pedagogy is the other signature: alongside the taught technique sit live gym rolls, Ryan defending his guard against a rotation of partners, followed by his own narration of what each pass was and why it failed. It is a competitor showing his own tape, not a coach teaching from first principles.
The relationship to Danaher's framework matters and should be stated plainly. The idea of retention as a taught, standalone subject — separated from any single guard, built from named skills, prized over recovery — belongs to Danaher's Go Further Faster treatment, and Ryan's system sits downstream of it, from the same room and the same lineage. What makes Ryan's a distinct system rather than a restatement is the organizing axis and the point of view: it is keyed to his loose-versus-tight passing taxonomy, aimed squarely at elite no-gi passing, and argued from the tape of the sport's best passer defending his own guard. The framework is the coach's; the no-gi competition application, the taxonomy it hangs on, and the footage that proves it are Ryan's.
The spine of the system is a single question asked before any pass has launched: is this a loose pass or a tight pass? Everything the defender does downstream is keyed to the answer, because the two kinds of pass want opposite things and are therefore beaten in opposite ways.
Against loose passing, the enemy is the reaction. A loose pass — the toreando above all — does not itself pass the guard. It is bait. The passer shucks the legs to one side, or steps around at distance, specifically to make the bottom player chase, extend a frame, or turn in the wrong direction; the actual pass is the tight consolidation that follows the moment the defender over-commits. So Ryan's retention against loose passing is built around not reacting the way the pass wants. The defender stays square to the passer, keeps the hips mobile, and answers the toreando with flank recovery — turning to face the passer and re-inserting the legs as the passer tries to circle to the hip — rather than with a desperate stiff-arm that gives the seam away. The seated posture is central here: sitting up, facing the passer, managing distance with the feet and hands so the loose pass has nothing to shuck. The rule underneath it is that a loose pass beaten early is beaten cheaply, because it has not yet touched anything worth defending.
Against tight passing, the enemy is the connection. Once a passer has closed the distance — a knee cut wedging across the thigh, a stack folding the hips, a body lock sealing chest to chest — the fight is no longer about distance and reaction. It is about attachment. A tight pass finishes when the passer gets the underhook, the crossface, and the chest connection that lets him consolidate and walk to a pin. Ryan's retention here is about denying those connections and keeping the defender's own structures between his chest and the passer's: the knee shield and half-guard frames that hold the crossface off, the butterfly hook and knee-lever mechanics that peel a stacking passer back off the hips, the inside-foot and hamstring controls that stop a knee cut from clearing. Where loose retention is about movement and reconnection, tight retention is about connection and structure — holding the frame that denies the pass the chest it needs.
Underneath both halves sits a leg game that is more entanglement than fence. Ryan retains heavily from single-leg X-guard and the ashi-garami family, treating the legs not as a passive barrier but as an active entanglement that both retains the guard and threatens the passer's own base and knees. This is the seam where his retention and his leg-lock game share a border: a passer forcing his way past the legs is a passer feeding them, and the same control that keeps the guard is one adjustment from a leg attack. It is a distinctly no-gi, distinctly Ryan feature — there is no sleeve or lapel to fall back on, so the entanglement does the gripping the gi would otherwise do.
The method by which all of this is taught is worth naming, because it is part of what makes it a system rather than a set of tips. Ryan works by weak-spot problem-solving: for each scenario he poses the central question — where, exactly, is this pass about to win, and what grip or foot position lets it — and then supplies the answers that close that specific seam before the pass launches. The emphasis is pre-emptive. Grip configuration and foot position are contested in the first frame, on the logic that the cheapest place to beat a pass is before it has started to move. That is why the live footage matters as pedagogy: it is Ryan demonstrating, in real time and against resisting partners, that the seam he named in the lecture is the seam that actually decides the exchange.
That is the line between this system and both its neighbors. A section on any one guard teaches you to retain that guard. The generic idea of "not getting passed" gives you movement and framing with no map of the passer's intent. And the Danaher retention curriculum gives you the principle-first, guard-agnostic foundation — the three skills and the passer's map — from which Ryan's system descends. What Ryan's adds, and what none of those can supply, is a no-gi retention game sorted by his loose-versus-tight passing taxonomy, aimed at the specific passes elite no-gi throws, and demonstrated on the tape of the person the rest of the division is trying to pass. Building that — the passing game read backwards, from the passer's own footage — is what makes it a distinct system.
By 2026 the loose-versus-tight vocabulary has escaped Ryan's own instructionals and become a common way the no-gi world talks about the passing exchange from both sides. Passers describe their game as loose-to-tight; defenders, increasingly, describe their retention as a loose-answer and a tight-answer rather than as a pile of guard-specific counters. That shared language is itself a marker of how far the framing has spread: a taxonomy becomes a system when other people start defending and attacking inside it.
The instructional market tracks the same spread. They Shall Not Pass sits alongside Ryan's passing and open-guard products in one of the sport's most heavily sold no-gi catalogs, and third-party study aids have followed — independent flowchart-makers have diagrammed the retention course volume by volume, which you can only do to a system that has a fixed structure to chart. The generic instruction to "keep moving and frame" has, for a generation of no-gi practitioners, been replaced by a two-branch decision — loose or tight — with a named answer down each branch.
The competitive home of the system is the room Ryan built. The New Wave–to–Kingsway lineage in Austin, and the wider no-gi elite that trains against Ryan's published game, drill this retention material as the defensive counterpart to the passing it mirrors. The most honest thing to say about its competitive footprint is that it is measured negatively: the athletes who train this way have their guards passed less often, and against better passers, which is precisely the kind of result that resists a highlight clip and a scoreline. That difficulty of proof is a property of retention itself, not a gap in the system — and it is the reason the section that follows is deliberately careful.
Guard retention resists the highlight reel by its nature. A leg-lock system produces a tap; a back-attack system produces a finish; a retention system produces an absence — a pass that never happened, a scoring position the passer never reached. There is rarely a single frozen frame that proves it, and attributing a specific match result to retention alone, rather than to the sweep, pass-reversal, or submission that followed, invites exactly the kind of unsourced storytelling this masthead avoids.
For that reason this section is deliberately thin, and the specifics are flagged rather than asserted. The general, defensible claim is that Ryan — and the competitors trained in his room — have been characterized repeatedly by opponents and analysts as extremely difficult to pass, and that this durability is consistent with the retention material Ryan codified and drilled. Any specific bout, edition, scoreline, or pass-attempt count that would turn that general claim into a cited example is listed in Known open items below, to be confirmed against event scoresheets and match archives before it appears in the body. A softened true sentence beats a specific false one, and a defensive system is precisely where that trade-off bites hardest.
White belt learns the single sorting question and nothing more: is the passer close or far? Far means a loose pass is coming and the job is to stay square and not chase; close means a tight pass is coming and the job is to keep a frame between the chest and the passer. Learning to ask that question before reacting is the whole white-belt lesson.
Blue belt learns to stop reacting the way a loose pass wants. The toreando is bait, and the blue-belt shift is to answer it with flank recovery — turning to face the passer and re-inserting the legs — instead of the stiff-arm that hands over the seam. The seated posture, and managing distance with the feet, is the blue-belt tool.
Purple belt learns the tight-passing half: the knee shield and half-guard frames, the inside-foot and hamstring controls that stop a knee cut clearing, the butterfly hook that peels a stack. The purple belt stops treating a passer who has closed the distance as a lost cause and starts fighting for the connection.
Brown belt learns the entanglement border — retaining from single-leg-X and ashi-garami so that a passer forcing the legs is a passer feeding them. Retention and leg attack stop being separate skills; the brown belt reads a forced pass as one adjustment from a leg entry.
Black belt runs the whole thing as one continuous read, keyed to the passer's intent rather than to any guard. The black belt does not think "I am in half guard, so I retain like this"; the black belt reads loose or tight, close or far, and answers with the same two-branch toolkit regardless of the starting position. Retention has become pre-emptive — the seam is closed before the pass launches.
1. Reacting the way a loose pass wants. The most common error, and the one the whole system is built to correct. Chasing a toreando with a stiff-arm, or turning away from a circling passer, gives up exactly the seam the loose pass was baiting. The fix is to stay square, keep the hips mobile, and recover the flank by facing the passer — beating the pass before it consolidates, not after.
2. Sorting the pass too late. The loose-versus-tight question has to be answered while the passer is still choosing, not after he has committed. A defender who waits until the knee cut is already across his thigh to decide it is a tight pass is no longer retaining; he is recovering from a worse position. Sort early.
3. Framing with muscle instead of structure. Against tight passing the crossface and chest connection are denied with skeletal frames — the knee shield, the forearm, the knee lever — not with a strength contest. The defender who arm-wrestles a body-lock passer fatigues and loses the late rounds of a hard match.
4. Treating the legs as a fence rather than an entanglement. A passer clearing the legs is not the end of the exchange; in the single-leg-X and ashi retention, a forced leg is a fed leg. Practitioners who let a cleared leg end the fight miss both the retention and the leg attack that shares its border.
5. Learning the techniques without the tape. The system is taught on live footage for a reason: the seams it names only become real when you watch them decide a resisting exchange. Drilling the positions cold, without the problem-solving read of where this pass wins, produces a defender who knows the shapes but not the moment.
Pick a side of the taxonomy this week and drill only that side. Start with loose passing: your partner is permitted only to toreando at controlled speed, and you are permitted only to stay square and recover the flank — no submissions, no sweeps, no standing up. Fifteen-minute round. The single objective is to keep at least one leg between you and your partner as he circles, and to answer his shuck by facing him rather than chasing.
You will get passed. Then you will get passed more slowly. Then you will keep a leg in for a whole round without stiff-arming. That progression — not any single retention — is the skill the loose half of the system is trying to build.
In the following weeks, switch to the tight half: your partner starts already connected — knee cut across the thigh, or a body lock — and you are permitted only to fight the crossface and the chest connection with frames, holding the knee shield and peeling the stack, until you recover a leg. Rotate the two constraints, and notice that the sorting question — loose or tight, react or connect — is the same decision under both. That transfer, from two drilled halves to one live read, is the system doing its job.
Ryan's retention system is the defensive mirror of the passing game that made his name, and it sits directly on top of the general skill of guard retention.
The through-line is method, not position: the same loose-versus-tight taxonomy that organizes Ryan's passing, turned around to organize his defense of the guard.
