Recovering guard from flattened half guard, in the gi

Pull his shoulder down, the lockdown and push, the fist under his jaw, the arm back under, lift him with the knees, turn to your side. They have the crossface and the underhook in half guard and you are flat on your back. The spine below is Gustavo Gasperin's recovery of the underhook in the gi, one coach and one route in his own orientation: cup the ball of his crossface shoulder and pull it down, the lockdown and extend your legs to push his head down, frame his forehead and put your fist under his jaw, shoot the arm back under for the underhook, both arms under him and lift him with your knees, and turn to your side. Bellingham's frames route, Chad Hardy's make-him-post and Chewjitsu's go-with-the-pressure are references from the same start, described for other nights, and so is Gasperin's own butterfly route, filmed no-gi; the sweeps from this position are references too. Sixteen gi clips, the spine clip in mixed kit (Gasperin in a gi, his partner in a rashguard and shorts) and three no-gi ones for the principles, every no-gi cue marked, transcripts read and cited to the transcript chunk, one orientation written out below.

Key takeaways

  1. Success means Off your back and onto your side with the underhook, his weight off your chest.
  2. The spine is 5 steps after the gate, cup the ball of his crossface shoulder and pull it down, the lockdown, and extend your legs to push him down, frame his forehead with the underhooked arm, then your right fist under his jaw, shoot the left arm under his right arm: the underhook back, both arms under him, knees to your chest, lift him up; then turn to your side.
  3. When it breaks there are 6 named branches; learn the triggers, the responses are short.
  4. Evidence: 20 clips from 18 channels (11 clips from a coach's own channel, 7 from a gym's, 2 from an instructional publisher's), every timestamp checked against the spoken transcript. Sentences marked synthesis are the editors', not a coach's.

what he has, and what it does

His arm under your head with his shoulder in your jaw, his other arm under your arm, your back flat, your face turned away. Danaher's account of the position: with a crossface and an underhook he can bend both of your shoulders to the mat, and that is what makes bottom half guard miserable; his three protections are the knee shield for distance, your own arm underneath his so he cannot pin your outside shoulder, and control of his crossface hand, and you have lost all three. Gasperin's account: there is no space, it is too tight, and it is very hard to go to your side and play your half guard.

space before anything

His shoulder off your jaw, his head pushed down and away, a frame under his jaw: room to move your head, then your arm. Gasperin's route makes the space in three small pieces before the arm goes back under: if his shoulder pressure is on your jaw, pull the shoulder down half an inch; push him down with your legs; frame under his jaw. The frames are forearm and fist, not a push with the hands. synthesis The order is his; that nothing else works before the shoulder is off is the author's reading of why he starts there.

a half guard you can play

The underhook back and you on your side, his chest off yours; his leg still between yours is what Gasperin means by playing his half guard from there, and the session asks the partner to keep it there. That is the endpoint: not the sweep, not the pass denied for a moment, but the half guard Gasperin can play from, which Bellingham's coach describes as three things together, one leg trapped, on your side, and frames or the underhook. synthesis Being on your side with the underhook is a better position than flat, not a guarantee against the pass; what you do from there is another document.

success means

synthesis On your right side with the underhook back and on top and his chest off yours, held for three seconds (the count is the session's test; the footage shows the lift and the turn), his leg kept between yours by the partner's agreement (the footage does not show it). Space under his shoulder is not the recovery; the underhook regained with you still flat is not the recovery; a knee wedged in with your shoulders on the mat is not the recovery; your side reached with his leg gone is a different position and a reset. B1 and B3 end where their coaches end them and do not claim this position.

the situation

You are flat on your back in half guard and he has both controls: chest to chest, his head beside your left shoulder, his left arm the crossface under your head with his shoulder in your jaw turning your face to your right, his right arm under your left arm as the underhook, your legs holding his left leg; your right hand is free; he has not yet cleared your leg, isolated your framing arm or switched his base (those are branches, threats and resets)

the endpoint

On your right side with your left underhook in and on top and his chest off yours, held for three seconds; the count is the session's test, the footage shows the lift onto the knees at 3:14 to 3:17.75, the turn onto the right side at 3:18 to 3:18.75 and the side reached at 3:19 to 3:20.25; his leg between your legs after the turn is not shown and is the session's cooperative condition

you start with

  • Your right hand is free
  • Your legs hold his leg

not solved here · cooperative resets

  • The mount completed after he clears your leg
  • Your framing arm wrapped for the kimura
  • Your back given by turning away
  • The crossface driven as a choke past half pressure (a tap, not a defence)
  • A belt or pants grip of his that the frames cannot open

Sides. One orientation throughout, Gasperin's own, mirrored when his head is at your right shoulder: he is chest to chest with his head beside your left shoulder; his left arm is the crossface under your head and his right arm the underhook under your left arm; his left leg is the leg your legs hold; your right hand is free and cups the ball of his left shoulder; your right leg is the inside leg under his left leg and holds it while your outside left leg crosses over his thigh to the inside, then your right lower leg crosses over your left and your right instep catches under his left ankle, for the lockdown; your left hand, the underhooked arm, frames his forehead and your right fist frames under his jaw; your left arm shoots back under his right arm for the underhook; both arms go under him and your knees lift him; you turn onto your right side with the underhook arm on top. Gasperin speaks in the ball of his shoulder, my elbow, the outside leg, his ankle, my ankles, the arm that is getting underhooked, my other hand, my wrist, my fist, my knees, my side; which arm, which leg and which side are read from stills of his clip, and the limitations say so.

what it is worth

IBJJF

Nothing scores for the recovery; it denies his pass. His pass scores 3 only once he has surmounted your legs and held side control or north-south for 3 seconds (article 4.2), and a half guard that still holds his leg blocks that count (4.2, note 2); the mount he is walking toward scores 4 once he is clear of the half guard, sitting on your torso facing your head, held 3 seconds (4.4). A position reached but not held may be an advantage (5.1, 5.2). None of this is a referee's call in training: the session's success is your side with the underhook back.

Article 4.2: 3 points when the athlete on top surmounts the legs of the opponent (pass guard or half guard) and maintains side control or north-south for 3 seconds; note 2: half guard is the guard where the athlete on bottom has one of the top athlete's legs trapped, blocking side or north-south control for 3 seconds; 4.4: mount 4 points when clear of the half guard, sitting on the torso with two knees or one foot and one knee on the ground, facing the head, with up to one arm trapped and the trapping leg not beyond the shoulder, for 3 seconds; 5.1 and 5.2: advantages for positions reached but not held or nearly completed

Gustavo Gasperin's recovery of the underhook

One coach's route from flat under the crossface and underhook to your side with the underhook back, in his own orientation: his head at your left shoulder, your right hand on his shoulder, the lockdown (your left leg over his thigh, your right instep under his ankle), the left hand on his forehead and the right fist under his jaw, the left arm back under, both arms under him and the knees lifting, the turn onto your right side with the underhook on top. Machado, the Bellingham coach and Danaher supply checks on what the position is and how to move under it, never a step. No step is conditional; the other routes are branches from the same start.

  1. GATE

    Read what he has: the crossface, the underhook, and no space

    His left arm under your head, his right arm under your left arm, your back flat and your face turned to your right; your right hand is the free one.

    This is the position after he beat you to the punch: you escaped the mount to half guard, shot for the underhook and blocked the crossface, and he got both anyway (0:00 to 0:42). His left arm is the crossface under your head, his shoulder in your jaw turning your face to your right; his right arm is the underhook under your left arm; his head is beside your left shoulder; your legs hold his left leg. There is no space and it is too tight to go to your side. Your right hand is free; your left arm is the one he has. Nothing here is a push with the hands.

    needsyour right hand is freegivesthe position readevidenceframes

  2. 1

    Cup the ball of his crossface shoulder and pull it down

    Right hand on the ball of his left shoulder, your elbow connected to your body, and pull the shoulder down; half an inch is enough to move your head.

    If his shoulder pressure is on your jaw, take care of that first. Your free right hand cups the ball of his left shoulder, the one crossfacing you; connect your elbow to your own body so the pull comes from your back, not your arm, and pull the shoulder down (1:06 to 1:26 in the stills, the right hand on his shoulder with the elbow in). If you pull it down half an inch it already helps: at least you can move your head a little.

    needsthe position read, your right hand is freegiveshis shoulder pulled downevidenceframes

  3. 2

    The lockdown, and extend your legs to push him down

    Your right leg is under his left leg as the half guard hook and holds his leg while your outside left leg lifts and crosses over his thigh to the inside, taking over the clamp; then your right lower leg crosses over your left lower leg and your right instep catches under his left ankle; then extend both legs so his head and his crossface shoulder go down.

    Now push him down even more, with your legs. Instead of locking a triangle to the outside, bring your outside leg to the inside and hook his ankle, then cross your ankles: that is the lockdown, and the stills say which leg does what (the wide shot at 1:41 to 1:47, .frames/lockhd-ZP6eavAmATU-1..3.png, and the close-up of the feet at quarter seconds, 1:43.5 to 1:47.25, .frames/feet-ZP6eavAmATU-1..4.png). Your right leg is the inside leg, under his left leg, and it holds his leg as the half guard hook while your outside left leg lifts (1:41 to 1:43.5) and crosses over his left thigh to the inside, taking over the clamp on his leg; then your right leg threads through: its lower leg crosses over your left lower leg and your right instep catches beneath his left ankle (1:44.5 to 1:45.25, the two feet crossing at 1:44.75). Nothing lets go during the change: his leg is held by the right leg until the left has it, then by the left while the right threads. Then extend both legs and push (1:46 to 1:52): his head goes down and the shoulder that is crossfacing you goes down with it. Now you can move your head, and there is more space for your underhook.

  4. 3

    Frame his forehead with the underhooked arm, then your right fist under his jaw

    The left hand, the arm he has underhooked, frames his forehead while the right hand still holds his shoulder; then the right hand leaves the shoulder and helps the left lift his head; then the right hand goes to his neck, wrist and closed fist under his jaw, and the left hand pushes his head higher.

    Still too tight? The hands go in this order, read at half seconds from the close-up (2:08 to 2:18, .frames/hands-ZP6eavAmATU-1..3.png; 2:19 to 2:30 at one-second steps, .frames/hands-ZP6eavAmATU-4..5.png). Your left hand, the arm he has underhooked, comes to his forehead first, at 2:10 to 2:11, while your right hand is still on the ball of his shoulder from step 1. Then the right hand leaves the shoulder (2:12.5 to 2:14.5) and joins the left on his head to help lift it (2:15 to 2:16.5: both hands at his head). Then the right hand lets go of that lift and goes to his neck: a frame under his jaw with your wrist and a closed fist, while the left hand reinforces it, first on the crown of his head pushing it higher (2:19 to 2:25), then, after lifting to gesture at 2:26 to 2:27, down beside the right fist at his jaw (2:28 to 2:30: the right fist under his jaw with the left hand beside it). The lockdown stays extended through all of it; that is what keeps his head down while the hands change. Now there is space to recover the underhook. Sometimes he breaks his grip, sometimes not; it does not matter, you only need the space.

  5. 4

    Shoot the left arm under his right arm: the underhook back

    Keep the right fist framing his jaw and shoot the left arm under his right arm to the underhook.

    Keep the right hand there, framing him, as you shoot your left arm back under his right arm and take the underhook (2:30 to 2:44 in the stills: the right fist stays under his jaw while the left arm goes under his arm; his head is still down beside your left shoulder and his right arm is still around your shoulder, not above your head, .frames/arm-ZP6eavAmATU-1..2.png). Do not try to go to your side yet: he is low on your body because you pushed him low, and he is still mashing your underhook, so it is still hard to turn. The lockdown is still on.

    needsthe frame under his jawgivesyour left underhookevidenceframes

  6. 5

    Both arms under him, knees to your chest, lift him up; then turn to your side

    The right hand off the jaw to his left lat, C-grips on his lats or armpits, knees to your chest and lift him all the way up with the lockdown still on, until his arm passes above your head; then turn onto your right side, the lockdown opening in the turn, and play half guard.

    Now the right hand leaves the jaw and goes under his left armpit to his lat, so that both arms are under him with a C-grip on his lats or in his armpits (2:44 to 2:56 in the stills, .frames/arm-ZP6eavAmATU-1..2.png: the right hand off the jaw and onto his left lat while the left arm stays under his right arm; he is still low, his head down beside your left shoulder and his right arm still around your shoulder, so the frame is given up for the second arm under him, not because his head is up). Then bring your knees close to your chest and lift him all the way up: the knees draw in at 3:12 to 3:13.5, and at 3:14 to 3:17.75 his chest is off yours and his weight is on your knees with his right arm passing above your head; the lockdown stays on through the lift, his left leg still between your crossed legs (.frames/lift-ZP6eavAmATU-1..2.png, .frames/turn-ZP6eavAmATU-1.png). Take any grip you can there and run your knees under his butt to bring him all the way up; the lift begins when both hands are on him and the knees are in, not before. Then turn onto your right side, the underhook arm on top (3:18 to 3:18.75, .frames/turn-ZP6eavAmATU-2..4.png and .frames/uncross-ZP6eavAmATU-1..2.png): your left arm rides over his back as your right shoulder and hip go down, and at 3:19 to 3:20.25 your back is to the camera, you are on your right side and knees with the left underhook in and his chest off yours. The lockdown opens in that turn: the right instep lets go of his ankle and the left leg, the crossing leg, lifts off. Hold the side for three seconds before anything else. synthesis The count is the session's test; Gasperin does not count, the clip cuts at 3:22 as he comes up to his knees, and what he plays from there is not in this document. Which contact keeps his leg as the lockdown opens, and whether his leg is still between your legs after the turn, is not shown: the lower legs are hidden behind the pair, the left leg rises at 3:20.5 to 3:21.25 and comes down at 3:21.5 as he comes up (.frames/legzoom-ZP6eavAmATU-1..3.png), and Gasperin says only that he can play his half guard from there. So the session does not claim it: the partner keeps his leg between yours as you turn, by agreement, and if it comes free the rep is a reset, not the endpoint.

— grip notes

Which arm, which leg, and what was read from the footage.

Gasperin says the ball of his shoulder, my elbow, the outside leg, his ankle, my ankles, the arm that is getting underhooked, my other hand, my wrist, my fist, my knees, my side. The stills add which: his head is beside your left shoulder; his left arm is the crossface and his right the underhook; the arm he has is your left and the free hand your right; the outside leg is your left and the leg your legs hold is his left; you turn onto your right side at the end, the underhook arm on top; what your legs keep of his leg in that turn is not read, because the stills hide it. The convention: a step marked transcript reproduces the cited speech; a step marked frames reproduces the speech and adds those assignments, read from 640p stills at two-second steps through the whole route (0:40 to 3:20, .frames/route-ZP6eavAmATU-1..4.png) and, for the lockdown, the hands, the re-pummel, the lift and the turn, from 1080p stills at quarter-, half- and one-second steps (.frames/feet-, lockhd-, hands-, arm-, lift-, turn- and after-ZP6eavAmATU-*.png). The camera is at medium distance and the pair is chest to chest; the stills show which hand and which leg are where at each sampled moment and the order of the contacts, not the pressure, and any side the reviewer reads differently is adopted.

Shoulders first, then hips.

Machado's rule for the crossface: do not try to move your hips first, it is very limited and he can free his leg while you do it; move your shoulders first, and when they move the hip goes up and the knee pops. Gasperin's first three steps are all shoulders and head; the legs push rather than shrimp. synthesis The pairing of the two coaches is the author's.

The hand that would have stopped this.

Danaher's third protection is control of his crossface hand at the sleeve cuff: with that hand held he cannot secure the crossface even with the underhook. It is the prevention for next time, not the escape; once the crossface is on, this document starts.

6 branches

Each one names the trigger you will feel, then the response. Learn the triggers; the responses are short.

B1
You would rather rebuild the frames and the knee shield than take the underhook back (the same flat start, Bellingham's route)reference onlya playable half guard: on your side, both frames inside, your top knee in front of his hip; Bellingham's own end, and their step to closed guard after it is their own

Bellingham BJJ's recovery, from the same flat start, in the coach's words; sides are not assigned. Turn the draped foot's toes down so you stay attached if he pulls away; step the other foot on the mat as close to your butt as you can with active toes; put your biceps against him where his ear meets his head, so he is moved off line rather than fought straight on; bridge into him and bring your frame inside, the other frame too if it comes, and if not, bridge again; then move your hips out like a shrimp and put your knee right in front of his hip. The frames are not grips: one hand rests on his shoulder and the other checks his biceps with the little finger where his elbow meets the biceps, so a squeeze on your face or a strike can be checked. Now if he comes forward he cannot, and you are on your side and can move. Their closed guard after it: step on the mat or his hip, switch the hips with a shrimp, extend, and close. synthesis Which foot drapes and which hand frames which side are not assigned from stills, so this is a reference, not a drill.

B2
You choose the butterfly hook instead of the underhook, from the same flat start (Gasperin's own second route, filmed no-gi)reference onlybutterfly guard with his weight elevated and pushed away; or, when the knee will not free, the single leg X if he posts and the sweep if he does not; Gasperin's own ends

Gasperin's butterfly route, an independent alternative from the same flat start under his crossface and underhook, not a continuation of step 4; in his own words and filmed no-gi, so every cue says so; sides are not assigned, so it is a reference, not a drill. Lean the crossface down with the shoulder grip, a little hip escape and, if it will not come, a bridge first, to get the butterfly hook in; then do not stay on your side, square up under him and go flat again on purpose, because the aim is to elevate the hook straight up and free the leg that is between his legs. Keep his head low with your hand, bring him forward with the knee against his butt, control his lats or neck, step the other foot on the ground if you can, and elevate, ninety percent hook and ten percent hand; wiggle the knee free, extend the legs and push him away into butterfly guard. If the leg will not free, change the angle and drive him sideways with the hook so he has to post; if he does not post he falls, and that is the sweep; if he posts and stays on that knee, run your thigh behind his knee and put the foot in front of his hip: the single leg X.

B3
His weight is driving into you so hard that you cannot bridge (Hardy's start, the same flat position)reference onlyeither the sweep, if he tips when you turn your knees, or the underhook back high with your elbow pulling you in and his foot wrapped, up on your side, if he posts; Hardy's own two ends, and his half guard after it is his own

Chad Hardy's answer, from the same flat start, in his own words; sides are not assigned, so it is a reference, not a drill. When he is pressuring so hard you cannot bridge, take the hand to his hip, keep your legs as tight as you can so he cannot slide (feet crossed if you fear the mount), tuck the elbow, push the hip and extend, and turn your knees. Two outcomes: if you can pinch and he tips, that is the sweep; with experience he posts out instead, and that gives you the space for the underhook. Then keep the underhook high, use your elbow on your knees to pull yourself in, circle the hand, wrap his foot and come up. synthesis A partner who neither tips nor posts is not shown: hold, release and reset. Hardy's own advice when one escape stalls is to chain to another rather than repeat it.

B4
He is driving forward into you and you cannot drive back (Chewjitsu's start)reference only

Chewjitsu's answer, in his own words: instead of going against the power, go with it, get underneath him so he has to post, and when he posts you have a free move: fight back to the underhook, or take the cross collar and make your distance, and get back to a defensible half guard. The bottom leg pipes down to block his base on the way under. Sides are not assigned; the hand exchanges are not read from stills; a reference.

B5
He clears your leg while you are still flat (the mount is coming)cooperative reset

synthesis No clip in this document recovers from the mount completed; the answers here are before it: Chang's rule is to cap his leg with the butterfly hook the moment your hips are out, because a leg grabbed with the hand alone lets him cut his shin over your body straight to the mount; Friedman's and the Fuse coach's passes show what he is doing (walking the toes up, dropping the hips, the knee through). In the session the mount completed is a hard boundary: stop, partner releases, restart from the entry.

B6
The crossface is being driven as a submission, or your framing arm is being isolated; or you have turned away from himcooperative reset

synthesis Three things end the drill, and each is a tap or a stop, partner releases, reset; none is fought. The crossface as a choke: the SBG coach shows the shoulder dropped straight down into the chest with the biceps against the neck, and his defence is a connection, the hand rotated thumb down to his neck and the body grabbed, not a reach for the choking hand, which only pulls your own elbow out; that defence is observation only here, and in the session the crossface is applied at half pressure and released on a tap. The arm isolated for a kimura while you frame: Giles's no-gi warning about a trapped arm belongs to his own position, after the top has switched base and climbed high, not to Gasperin's frames; the caught-arm stop here is the author's. Turning away to your stomach gives him the back and is a stop, not a scramble.

— negate first

Threat map

Some of the clips on the left show the coach performing the attack; watch them once so you recognise it. The answer on the right is a spine step, a branch, or marked as synthesis.

The crossface driven as a submission

your answer

Recognise it: his biceps on your neck and his shoulder sinking straight down into your chest, not across your jaw. synthesis The session's answer is a tap: stop, partner releases, reset; the SBG coach's connection defence is observation only here and is not attempted before the tap. In the route the shoulder is pulled down before it sinks (step 1). Do not reach for his choking hand.

The mount when your leg opens

your answer

Recognise it: the moment your legs open to move, his knee comes across. Gasperin's lockdown (step 2) keeps his leg while the legs push; Chang caps the leg with the hook and holds it with the hand before he undoes his squeeze; Bellingham's coach turns the draped toes down instead of locking. synthesis A cleared leg with you still flat is the B5 reset.

His switch of base once you have the knee back

your answer

Recognise it: once you are on your side he switches his hips to face your legs. Giles's no-gi rule is the bottom knee pointing up, ready to come in front of his hip, and no pushing away with the shield. It is the next problem, not this document's; the rep ends at the endpoint before it, and in the session a switch of base at any point is a stop and a reset.

The kimura on the arm that frames

your answer

Recognise it: a frame he can wrap. Giles's warning is spoken for his own position, after the top has switched base and climbed high; synthesis the author's rule for Gasperin's frames is the same in spirit, the elbow in and the fist under the jaw rather than an arm extended across him, and a wrapped wrist is a tap and the B6 reset.

What he wants next: the pass

your answer

Recognise the plan: the crossface and underhook exist to keep you flat while he walks the leg free. synthesis The route first moves his head and shoulder down (steps 1 and 2) and only then lifts him (step 5); on your side with the underhook you can play, which is a better position than flat, not a guarantee, and a flat man with a knee in is not there yet.

— 20 minutes · gi

Tonight

synthesis The session is the author's; the mechanics are Gasperin's, from one exact start: flat, with both of his controls on. Every full-route rep ends at the spine's endpoint, your right side with the underhook in and his chest off yours, counted to three, his leg kept between yours by agreement, or at a named reset; the first block ends at the step 2 standard and resets; no other route is played, and the other coaches' routes are references. Two kinds of stop: the block's own reset, cooperative and named under each block, and the hard boundaries the scope lists (the mount completed; a wrapped framing arm; your back turned; the crossface driven as a choke), which stop everything; both restart only after the partner releases every control.

safety · stop here

No submission is attacked in this document. The crossface loads your jaw and neck and can be driven as a choke: the session applies it at half pressure and releases on a tap, and the shoulder is pulled down (step 1) before anything else. A framing arm can be wrapped for a kimura: a caught wrist is a tap. The lockdown loads his knee if it is extended while his leg is turned out: extend straight, slowly, and release on his tap. The sweeps in the reference are observation only. The release rules are the author's.

  • The crossface driven into the jaw or as a choke (every block). Half pressure; the bottom taps and the partner releases at once; the shoulder pulled down is step 1, not a fight against the pressure
  • His knee under the lockdown (step 2). Extend the legs straight and slowly; if his leg is turned out or he taps, release at once; the push is to move his head down, not to crank the knee
  • Your framing arm wrapped for the kimura (B6). Tap early and reset; the arm stays high under his arm or framing with the elbow in
  • The sweeps in the reference (Kesting's kamikaze and twist, Chang's, McInally's, Inverted Gear's, RGA's). Not drilled; observation only

    4 min

    He settles flat on you with the crossface at half pressure and the underhook, his hand open on your back. Right hand to the ball of his left shoulder, elbow to your body, pull down; then the lockdown: the right leg keeps his leg while the left leg lifts and crosses over his thigh to the inside, then the right lower leg crosses over the left and the right instep catches under his ankle, extend and push until his head goes down. Say the two out loud: shoulder, push. Each rep ends there, at the step 2 standard: hold the push for a breath, release, and reset. Ten reps, swap.

    start
    You are flat on your back in half guard; he is chest to chest with his head beside your left shoulder, his left arm the crossface under your head with his shoulder in your jaw turning your face to your right, his right arm under your left arm as the underhook, your legs holding his left leg; your right hand is free; he applies the crossface at half pressure

    From the exact start, cooperatively: the shoulder pulled down with the right hand; the lockdown (the left leg over his thigh to the inside, the right lower leg over the left and the right instep under his ankle) and the push; the left hand to his forehead while the right still holds the shoulder; the right hand off the shoulder to help lift his head; the right hand off the lift to the fist under his jaw, the left on top pushing higher; the left arm back under his right arm with the right fist still framing; the right hand off the jaw to his left lat; knees to the chest and lift him with the lockdown still on until his arm passes above your head, knees under his hips; turn onto your right side with the underhook arm on top, the lockdown opening in the turn while he keeps his leg between yours by agreement, and count three out loud. He resists lightly only by keeping his shoulder heavy. Ten reps, swap, then the mirror side (his head at your right shoulder, his right arm the crossface, his left arm the underhook, your left hand free, the turn onto your left side) with every hand and foot swapped.

    start
    You are flat on your back in half guard; he is chest to chest with his head beside your left shoulder, his left arm the crossface under your head with his shoulder in your jaw turning your face to your right, his right arm under your left arm as the underhook, your legs holding his left leg; your right hand is free; he applies the crossface at half pressure
    practises
    steps G, 1, 2, 3, 4, 5
    success
    On your right side with your left underhook in and on top and his chest off yours, held for three seconds (the count is the session's test); his leg between your legs is the session's cooperative condition, kept there by the partner as you turn, not a contact the footage shows
    reset
    If he clears your leg while you are flat (B5), if your framing arm is wrapped (B6), or if you turn away, stop, partner releases, restart

    The route under resistance, in three grades

    5 min

    Every rep is the whole route from the same flat start with the position read; what changes is how he holds. Grade one, three reps: he keeps the shoulder heavy and his ear tight but lets the legs push him and does not chase the arm. Grade two, three reps: he keeps the shoulder heavy and resists the push with his hips, and lets the arm go under once the frame is there. Grade three, three reps: he holds as in a round, without the choke, the kimura hunt or the switch of base; the order does not change: shoulder, lockdown and push, forehead, jaw, arm under, lat, lift, turn. In every grade a lost required control is a stop, release and reset; nothing is rebuilt from what remains. The one restoration allowed is the push and the forehead contact, and only while the lockdown is installed and intact and the shoulder is still pulled down with the right hand: extend the legs again and re-place the left hand. No control is skipped and none is taken out of order. Each rep ends at the endpoint with the count. Swap after each grade.

    start
    You are flat on your back in half guard; he is chest to chest with his head beside your left shoulder, his left arm the crossface under your head with his shoulder in your jaw turning your face to your right, his right arm under your left arm as the underhook, your legs holding his left leg; your right hand is free; he applies the crossface at half pressure
    practises
    steps G, 1, 2, 3, 4, 5
    success
    On your right side with your left underhook in and on top and his chest off yours, held for three seconds (the count is the session's test); his leg between your legs is the session's cooperative condition, kept there by the partner as you turn, not a contact the footage shows, reached at each grade of resistance
    reset
    If he clears your leg while you are flat (B5), if your framing arm is wrapped (B6), if the crossface is driven as a choke (tap), or if you turn away, stop, partner releases, restart; if the arm cannot get back under at a grade, drop back a grade rather than force it
  4. 4

    Positional rounds

    5 min

    Five one-minute rounds from the exact start, alternating who is on top. He keeps you flat for real with the crossface at half pressure and works to clear the leg; he does not drive the crossface as a choke, does not hunt the framing arm for a kimura, and does not switch base at any point in these rounds, because none of those is installed tonight; a switch of base before the endpoint is a stop, release and reset. The route is the only escape played; the other coaches' routes are references tonight. The spine's success is your side with the underhook, his chest off yours and his leg still held. The mount completed, a wrapped arm, the crossface driven as a choke or your back turned is a tap or a reset, not a scramble.

    start
    You are flat on your back in half guard; he is chest to chest with his head beside your left shoulder, his left arm the crossface under your head with his shoulder in your jaw turning your face to your right, his right arm under your left arm as the underhook, your legs holding his left leg; your right hand is free; he applies the crossface at half pressure
    practises
    steps G, 1, 2, 3, 4, 5
    success
    On your right side with the underhook in and on top and his chest off yours, held three seconds, his leg kept between yours by agreement (the spine's success); anything else is a reset
    reset
    Restart on the endpoint reached and counted, on the mount completed, on a wrapped framing arm, on your back turned, on his leg coming free in the turn, on a switch of base at any point, or on a tap; sweeps are not played, and the crossface is never driven past half pressure
Not tonight.B1 (Bellingham's frames route), B2 (Gasperin's butterfly route, filmed no-gi), B3 (Hardy's make-him-post) and B4 (Chewjitsu's go-with-the-pressure) are references from the same start with their own ends; each becomes a drill only once its sides, contacts and exchanges are read from stills in this document's orientation. The sweeps in the reference (Kesting, Chang, McInally, Inverted Gear, RGA) are observation only.

It happenedCheck first
You could not move your headWas the right hand on the ball of his shoulder with your elbow connected to your body, or was it a push with the hand? Did the lockdown go on with the right leg keeping his leg, and did both legs extend before you tried the frame?
The frame went in and he drove through itWas it the fist and wrist under his jaw with the other hand pushing his head higher, or an open hand on his chest? Was the shoulder already pulled down?
The arm would not go back underDid the right fist stay framing while the left arm shot under, or did you let the frame go first? Was his head pushed down by the legs before you tried? Did the right hand leave the jaw for his lat only after the underhook was in?
You got the underhook and could not turnDid you try to turn before lifting him? Were both arms under him with the knees to your chest, and did his arm pass above your head before you turned?
Your leg opened and he cleared itDid the lockdown come off before the frame was in, or did the ankles uncross while you re-pummelled? A cleared leg while you are flat is the B5 reset.
Your framing arm got wrappedWas the elbow in and the fist under his jaw, or was the arm extended across him? A wrapped wrist is a tap and the B6 reset.

  • Evidence convention: a step marked transcript reproduces the cited speech; a step marked frames reproduces the speech and adds hand, arm, leg and side assignments read from stills: 640p at two-second steps for the whole route, and 1080p at quarter-, half- and one-second steps for the lockdown, the hands, the re-pummel, the lift and the turn. G and steps 1 to 5 are marked frames for: his head at your left shoulder with his left arm the crossface and his right the underhook, your left arm underhooked and your right hand free, your left leg the outside leg of the lockdown and his left leg the leg held, the right hand on the ball of his shoulder (1:06 to 1:26), the lockdown (the right leg under his leg holding it while the left leg lifts at 1:41 to 1:43.5 and crosses over his thigh to the inside, then the right lower leg over the left lower leg and the right instep under his left ankle at 1:44.5 to 1:45.25, the extension at 1:46 to 1:52; .frames/lockhd-ZP6eavAmATU-1..3.png and .frames/feet-ZP6eavAmATU-1..4.png), the left hand to his forehead at 2:10 to 2:11 with the right hand still on his shoulder, the right hand off the shoulder at 2:12.5 to 2:14.5 and onto his head at 2:15 to 2:16.5, the right fist under his jaw with the left hand on the crown of his head at 2:19 to 2:25 and beside the fist at 2:28 to 2:30 (.frames/hands-ZP6eavAmATU-1..5.png), the left arm shot back under with his head still down and his right arm still around your shoulder (2:30 to 2:44), the right hand off the jaw to his left lat (2:44 to 2:56; .frames/arm-ZP6eavAmATU-1..2.png), the knees drawn in at 3:12 to 3:13.5 and the lift with the lockdown still on at 3:14 to 3:17.75 (.frames/lift-ZP6eavAmATU-1..2.png), the turn onto the right side with the left underhook on top at 3:18 to 3:18.75 and the side reached at 3:19 to 3:20.25 (.frames/turn-ZP6eavAmATU-1..4.png, .frames/uncross-ZP6eavAmATU-1..5.png), the lower legs hidden behind the pair after the turn and the left leg rising at 3:20.5 to 3:21.25 (.frames/legzoom-ZP6eavAmATU-1..3.png; no leg contact is read from them) (ZP6eavAmATU at two-second steps 0:40 to 3:20, .frames/route-ZP6eavAmATU-1..4.png, and close crops at those moments, .frames/zoom-ZP6eavAmATU-1..3.png). The camera is at medium distance and the pair is chest to chest, so the stills settle which hand and which leg and the order at the sampled moments, not the pressure and not the moments between samples; a side the reviewer reads differently is adopted.
  • The endpoint is the right side reached at 3:19 to 3:20.25 after the lift (3:14 to 3:17.75) and the turn (3:18 to 3:18.75); the three-second hold is the session's test and is not in the footage, and the clip cuts at 3:22 as Gasperin comes up to his knees. At 3:19 to 3:20.25 his chest is off Gasperin's and he is on his own hands and knees, so 'his weight on your knees' describes the lift, not the endpoint. The second and third drafts said the turn was to the left side; the reviewer's reading of the turn sheets is adopted and checked: Gasperin's left arm rides over the partner's back and his right shoulder and hip go down, so the turn is onto the right side with the left underhook on top. Which contact keeps his leg as the lockdown opens, and whether his leg is still between Gasperin's legs after the turn, is not shown: the lower legs are hidden behind the pair, the left leg rises at 3:20.5 to 3:21.25 and comes down at 3:21.5 as he comes up, and Gasperin says only that he can play his half guard from there. The fourth draft claimed a return of the left leg over his leg at 3:20.5 to 3:21.25 and a right leg beneath it; both claims are withdrawn. The endpoint therefore claims the side and the underhook only, and the session's requirement that his leg stays between yours is a cooperative instruction, the author's, with a reset when it comes free.
  • The hand transfers are read at half seconds from the 1080p close-up: the left hand frames the forehead at 2:10 to 2:11 while the right hand still holds the shoulder; the right hand leaves the shoulder at 2:12.5 to 2:14.5 and joins on his head at 2:15 to 2:16.5; the right fist is under his jaw with the left hand on the crown of his head at 2:19 to 2:25 and, after the gesture at 2:26 to 2:27, beside the fist at 2:28 to 2:30; the left arm re-pummels at 2:30 to 2:44 with his head still down and his right arm still around the shoulder; the right hand leaves the jaw for his left lat at 2:44 to 2:56. The second draft had the right hand leaving the shoulder before the forehead frame, claimed his arm above the head at 2:44 and had the session open the lockdown as the knees came in; the reviewer's readings are adopted: the lockdown is on through the lift at 3:14 to 3:17.75 and opens in the turn at 3:18, and the substantial lift and the arm clearing the head are at 3:14 to 3:17.75.
  • The spine range covers Gasperin's instruction only, 0:00 to 3:22, demonstrated once with the camera moving closer at about 2:04; there is no separate recap.
  • Bellingham's coach is not named on the channel or in the clip and is credited through the gym; Hardy's, Chewjitsu's and Bellingham's sides and hand exchanges are not read from stills, so B1, B3 and B4 are references, not drills, and the session rehearses the spine alone; the limitation is said in each.
  • Gasperin's butterfly route (B2) is filmed no-gi; it is his own second answer from the same start and is kept as a drill for another night with every cue prefixed no-gi, because no gi clip in this set teaches the same route.
  • The ADCC sidebar is omitted: this is a gi document.
  • Three no-gi clips are cited (Gasperin's butterfly route, Coach Nate's knee shield, Giles's switch base), in the checks, the branches, the threats and the reference, every cue prefixed no-gi; sixteen gi clips and the spine clip in mixed kit are cited. The rest of the thirty-four clips considered are excluded with reasons.
  • The system has not been tested on the mat by its editors.
  • Three kit readings on excluded clips were wrong in the first draft (TvTt3cAf0RM, _XovOvE_Bwg and n9xtTZlFLfI are gi) and are corrected in the clip index; their exclusions rest on provenance or on the coach not yet being identified, not on kit. xNIGPeEUB0A carries a WHITEBELT JIU-JITSU watermark and is excluded as a suspected re-upload pending qualification.
  • The first draft assigned the lockdown's ankle hook to the left foot with the right foot crossing over the left ankle; the reviewer's quarter-second reading of the close-up (1:42.75 to 1:45.25) is adopted and checked against .frames/feet-ZP6eavAmATU-1..4.png: the outside left leg crosses over his thigh first and takes over the clamp, then the right lower leg crosses over the left lower leg and the right instep catches beneath his left ankle; the two feet cross at 1:44.75.
  • The Legion clip (n9xtTZlFLfI) is gi and its instructor gives his first name as Logan at 7:17 and names his partner Jason Baker; no surname is spoken in the captions or shown on the channel, so the coach is not yet identified and the clip stays excluded on that ground. The Next Generation Martial Arts channel is titled 'Jiu Jitsu | Next Generation Martial Arts Thibodaux'; the bar in the title broke the first probe (the handle, availability and subscriber fields were shifted) and the record is re-probed and corrected.
  • The spine clip is mixed kit: Gasperin wears a white gi with a red patch, his partner a black short-sleeved top and gray shorts with bare knees (.frames/lift-ZP6eavAmATU-2.png, .frames/uncross-ZP6eavAmATU-5.png); the first reading of the clip index ('white gi over a black gi') was wrong and is corrected. None of Gasperin's contacts in the route is a cloth grip (the ball of the shoulder, the lockdown, the forehead and jaw frames, the underhook, the lats), so the route is the same in either kit; the document stays a gi document because Gasperin plays it in the gi and every other cited clip but the three no-gi ones is gi.
