High Percentage Leg Locks — Volume 04: Standing Opponent, Sweeps, Back-Takes, and the Top 50/50 Game
Lachlan Giles closes the system with the four scenarios that complete the 50/50 game — heel hooks against a standing opponent (three exposure methods including a finish he hit in the ADCC trials final), sweeps and back-takes for points competition, what to do when you come up on top, and how to disengage safely or finish with a knee bar.
Distilled from the verbatim transcript. Every concept is preserved; verbal filler, partner demos, and repetition are not. Each section header links to the exact moment in the Bilibili video. Volume 04 is the most drill-heavy in the series — line count is highest while runtime is comparable to Volume 03 — so compression is the most aggressive here. The conceptual coverage is complete.

Part I — Standing opponent in 50/50
1. Standing opponent overview
0:00–1:12 · ▶ Watch
When partner stands up out of 50/50: is it a good idea? Generally no, unless points are on the line and you have to. The reason: standing partner has lost the other leg as a heel defender. Their hands aren't defending the heel either. A momentary heel exposure becomes a catch — fast.
Lift the heel off the ground for even a second and you have a chance to dig it.
2. Knee safety in 50/50: LCL warnings
1:12–3:26 · ▶ Watch
The knee is not designed to bend sideways. This is how the LCL tears. A lot of injuries happen in 50/50; the patterns are predictable.
From the top
Common mistake: pressure pass through 50/50. You can't remove partner's leg with forward pressure — and if your knee is turned out and partner kicks back, the knee twists sideways. Potential surgery.
The fix: knee turned in when on top, fight from there. If partner off-balances you and the knee is turned in, go with it — don't fight genuine momentum.
From the bottom
If partner is pressuring forward into you, don't push out against the pressure with one leg. Pushing against incoming pressure puts the force directly on the lateral ligament. Same injury, opposite direction.
The exception: reinforce with the other leg. Left foot supports, reduces inward pressure on the knee. Pushing-out-against-pressure is fine if the other leg is anchoring.
If they're pressuring you in a way you can't safely resist: off-balance them with both feet together; reset.
3. Three exposure methods overview
3:26–4:20 · ▶ Watch
Three ways to expose partner's heel against a standing opponent:
- Knock to the side — off-balance lifts the heel; catch as it comes up.
- Spin under — head between partner's legs; spin pressures the knee inward, lifts the heel.
- Spin over the top — hip out, spin over partner's leg to expose the heel and catch.
These get covered in detail and combined as a chain.
4. Key concepts: losing knee line, opening legs
4:20–6:27 · ▶ Watch
Two principles that change how you play bottom 50/50 against a standing opponent.
It's okay to open your legs
Counter to most positions, you can open the legs here. Keep the heel low — partner can't easily pull a low-hung leg up to the armpit to catch you (they'd have to lift your full body weight off it). Opening the legs gives you the other leg as a momentum tool for the spin-under, off-balance, and spin-over.
Caveat: if partner is genuinely low and pulling your leg high, you still have to watch for the counter. But foot near the hip with weight on it is generally safe.
It's okay to lose the knee line
If you focus on keeping the hips high, you struggle to rotate. Often it's better to drop the hips low — easier to spin, easier to reclaim the knee line through the spin itself.
What keeps the knee line: knee tight, chest tight, armpit tight, free leg pulling — same pressure principles as the rest of the system. If you can get rotation, partner twists their knee, the heel lifts, you catch.
5. Method 1: Knock to the side
6:27–9:23 · ▶ Watch
The simplest exposure. Cross feet (or open with hand on knee), off-balance sideways, catch as the heel lifts.
Crossed-feet version
- Feet crossed, left foot tight to ribs — keep toes mid-rib level, not at the armpit.
- Watch the toe hold — if the foot is out, partner has a free shot. Open the legs if worried.
- Twist the knees to off-balance — as partner falls, the heel lifts.
- Dig under, false grip, connect feet, twist or rotate to outside Sankaku finish.
If they're upright: double feet on hips, chest and bridge. Side of the knee, great pressure for the finish.
Open-legs version (with pendulum)
If the cross-feet doesn't off-balance cleanly:
- Open legs but hold the top of partner's knee to stop them stepping out.
- Pendulum with the free leg — generates more momentum than the static twist.
- Hold the knee so they don't reset to attack position after the off-balance.
6. Method 2: Spin under — basic
9:23–10:36 · ▶ Watch
The easiest version: reach partner's far leg and spin.
- Head between partner's legs.
- Reach the far leg — right hand first, left hand second is ideal.
- Keep spinning. The pressure on partner's knee from your head/spine geometry pushes it inward.
- The heel lifts. Catch it. Triangle. Bridge.
No inversion needed if you can reach the far leg.
7. Spin under troubleshooting
10:36–13:48 · ▶ Watch
Things that make the spin-under hard against a good defender:
- Partner holding your knee up high → you can't drop under. Solution: let the knee free, drop it, spin through, reclaim the knee line as you catch.
- Partner stepping near your armpit → you can't curl in. Wiggle back so the foot is lower on the body.
- Partner turning their leg far away → you can't reach to pull yourself through.
The fix when multiple problems compound
- Block so partner can't follow with the foot; wiggle back.
- Open legs, free the knee. Even hold your own leg if you're not flexible enough.
- If partner tries to step over now, it's stuck because your knee is free and trapping.
- Use the left hand on the ground; almost a back-roll.
- Swing back to gain angle; cut around the corner; calf/Achilles behind partner's knee.
- Shoot the leg back through, take the heel.
Alternative framing
Aim your calf-near-Achilles behind the back of partner's knee. That's a weird angle but it works — kick from there to drag partner's knee forward, shoot back to catch.
8. Force the spin: push back to make space
13:48–14:55 · ▶ Watch
When partner steps right under your armpit and balances well — too tight to spin normally:
- Push with the hand; scoot back; spin immediately.
- Step on partner's hip with the left foot heel — pushes off.
- Up on the left hand, sort of seated forward.
- Partner's ankle is now near your hip — back-roll / shoulder roll into the catch.
The forced-spin gets you the same geometry by force when partner is preventing the natural setup.
9. Method 3: Spin over the top — the ADCC trials finish
14:55–21:33 · ▶ Watch
When partner drops weight and turns their knee in — too low and too tight to spin under — go over the top.
The setup
Partner steps back, knees in, sometimes even reaches under their own leg to your far hip. Their knee is turned in. The spin-under is blocked.
The grip — lat-locked-to-Achilles
This is the key mechanical detail. From this position:
- Get your lat above the line of partner's Achilles.
- The lat physically traps the heel when partner tries to free it. Try to pull away with the heel — stuck.
- This is different from a regular grip where partner can just run and free the heel.
The roll-over
- Optional: left foot hooks partner's body to initiate.
- Step on partner's body, not the floor — aim is to lift partner's foot off the ground.
- Hips out to the right; foot off the ground.
- Knee bar is now available, but Lachlan prefers the heel hook — higher percentage.
- Grip mid-shin, not at the ankle.
- Swing the leg over; turn partner's knee inward. Heel catches.
- Chop behind the knee, not at the hip. Most common mistake.
The ADCC trials final
Lachlan hit this exact technique in the ADCC trials final. Partner was turning and running away; Lachlan hipped out, shot over the top, caught the heel. The opponent then back-stepped — Lachlan's follow was bridging through.
Even when partner is pressuring and staying on top in 50/50: knock them forward slightly, get out on the hip, nice high grip, swing over the top.
Mechanical detail
- Lat to heel (locking).
- Step on partner's back/body with the right foot.
- Hips out wide.
- Lift hips up and over.
- Chop the right leg through.
- Roll through.
- Foot over now, finish.
10. Stacking counter: lock feet and invert
21:33–23:22 · ▶ Watch
When partner comes on top and stacks you — heel isn't immediately accessible — invert.
- Lock the shoulder so they can't catch your own heel or pin your legs.
- Feet together; left foot supports right foot.
- Keep heavy on the knee.
- Extend the legs — partner's hips/knees come up.
- Reach under the far leg; spin through; catch the heel as you arrive.
The feet-together-extension pushes partner away cleanly. Without the lock, partner sometimes catches your heel as you try.
11. Counter when partner does not commit weight
23:22–24:29 · ▶ Watch
If partner stacks but doesn't fully commit weight forward, you can't back-roll easily. The fix: chop the knee outwards to make them push back against the chop, which brings their weight forward.
You can also try to reap. Either way, force them to commit weight, then exploit the commitment with the back-roll + heel catch.
12. Linking standing-opponent techniques
24:29–26:42 · ▶ Watch
The chain.
- Don't leave the foot dangling — toe hold waiting to happen.
- Don't be afraid to drop hips, open legs, clear the knee line.
- Default: knock to the side, catch the heel as it lifts.
- If partner steps forward to prevent it: spin under to catch.
- If spinning under is difficult: open legs, drop knees, wiggle back to get foot lower on the body, then spin again. Calf behind partner's knee, chop through.
- If partner commits knee in and weight down: spin over the top with the lat-Achilles grip.
The point is to mix the three together. Partner can't defend all of them at once. If they resist one, the other opens. The combination is the game.
Part II — Sweeps and back-takes from bottom 50/50
13. The "free leg on bottom" rule
26:42–29:32 · ▶ Watch
When the heel hook isn't available but points matter, sweep instead.
The structural principle
It's next to impossible to get up if your trapped leg is on the downward side. The trapped foot ends up elevated relative to your knee; you can't retract.
If the free leg is on the downward side, you can retract that leg into the get-up — you always win the get-up battle.
So: when bottom 50/50, get on your side where your free leg is on the bottom.
Reverse the scenario and you lose the get-up race every time.
The strategic upshot
This rule structurally determines who can sweep. As soon as you hit the ground in 50/50, race to be on the right side. The heel-hook setups from earlier double as sweep setups — same mechanics, points outcome instead of submission.
14. Pendulum and spin-under sweeps
29:32–31:21 · ▶ Watch
Sweep mechanics ride on the same setups as the heel-hook attacks.
- Pendulum sweep: get on the left side, come up. If partner resists the pendulum, spin under — and the spin lands you on the left hip, so you sweep from there too.
- Over the top: if partner is based, get to the same outside Sankaku-style position you'd use for the heel hook — but instead of the catch, just stand up. Trapped leg gives you leverage; partner can't win the get-up battle.
The principle: same setups, but if heel hooks aren't legal, the sweep is the secondary outcome of the same fight. If they're legal, take the heel hook — it's the match.
15. Back-take with thigh hook
31:21–39:50 · ▶ Watch
Back-take from 50/50. Doesn't help catch the heel, so it wasn't covered earlier — but it's one of the best options apart from outside Sankaku.
Setup
Pendulum doesn't work → partner has to step back to keep balance. That step gives you the hook.
- Hook in front of partner's thigh. This blocks partner from turning to face you fully — you can follow.
- Get your knee right behind partner's knee.
Knee placement
Pulling your knee through partner's leg is rare and risky (kneebar exposure). More common: take the foot out, kick through, knees together, flare out. Now you have two hooks active. If both hooks are sharp, partner can't turn left or right.
Reach for the far ankle
Change grip from overhook to ankle.
- Top hook stays high on the thigh — higher on the thigh, harder to push down and clear.
- Take the time to get the far side. Partner will try to push the top hook down and step out — your job is to be quick.
Two finishing paths
Path A — push to hips: Push forward with shins/knees. Knock partner down, attach to hips. Scoot back, tuck one foot behind, come up to seat belt and take the back.
Path B — pull to chest: If partner sits back / pushes back instead of going down, pull them onto you. Knees to chest, lift with feet, extend away. Then catch the harness — knees pressuring in, feet pressuring out (the dual hook pattern). Keep the seat belt; take the back.
The first path is the default; the second is the answer when partner resists the push.
16. The dragon's tail standup variant
39:50–44:50 · ▶ Watch
Sometimes you can just stand up. Partner pushes your foot down, brings their knee over the top — you catch the ankle, drop them to their knee.
Mechanics
- Hook the ankle to limit partner's mobility.
- Grip the knee.
- Take the 50/50 leg out (usually a bad idea, but here it's good).
- Scoot it around; scoot hips in close.
- Lock feet down near the ankles, not as a triangle.
This is the dragon's tail position — essentially a lockdown with partner's leg on the far side. Strong positioning for you.
From the dragon's tail
- Extend to stretch partner out.
- Take partner's leg, stretch them so both their feet are off the ground.
- No post = sweep and back-take options open up.
17. Back-take details and the Camorra grip
44:50–48:46 · ▶ Watch
The back-take refined.
Taking partner's hips high
Don't just lock feet and go for the back — partner may underhook and counter. Bring partner's hips higher on your chest. Use your knee to bump behind partner's hips; pull knees to chest. Take partner's foot off the ground.
Once partner's hips are high, the counter underhook is gone — their shoulder is in a bad position.
Camorra grip
- Best grip: Camorra on the arm. If not available, just hug the arm — don't let it free.
- Use the hands to stretch partner's leg, bringing them forward.
- Push the leg away with the hand to expose partner's back.
The switch
- High back-heel on the right leg (stops partner bringing their knee in).
- Switch feet — left foot becomes the hook.
- Right leg comes out and shoots behind partner.
- Take the back.
The mechanic: knee behind the shoulder, shoot through, sit down to the side. If you put the knee anywhere except behind the shoulder, partner can hip out around it.
18. The Mehdi brothers same-ankle variant
48:46–50:43 · ▶ Watch
A specific high-level 50/50 strategy: partner grips the same ankle as you, mirror grip.
The escape
- Step with the left foot on partner's far leg.
- Use it to get out on your side.
- Get up on the elbow.
- Kick to retract; take the foot back; both end up standing.
The thing is: by stepping on the far leg and turning, you take partner's heel off the ground. That positions you on the left hip — your free leg on the bottom, which means you win the get-up battle.
If you're more pressured down in this direction, you might be able to take partner down with your leg not in the way. Two flexible players → likely a stalemate. This is the Mehdi brothers' grip that Lachlan has been using a lot.
19. Summary: 50/50 sweeping options
50:43–53:35 · ▶ Watch
The complete sweeping menu.
- Pendulum to knock partner over → get on left hip → up.
- Spin under if pendulum doesn't work → lands on left hip → up.
- Hook the leg in front of the thigh if partner steps back to defend → back-take.
- Pull onto us and extend if partner sits back instead of forward → back-take.
- Stand-up + dragon's tail if hook doesn't catch → sweep back, or bump forward, stretch out, hook the back.
The decision tree
What determines which one:
- Weight forward or up? Forward → spin under. Up → pendulum.
- Stepping leg forward or back? Back → hook to take the back. Forward → spin/pendulum to sweep.
- Foot out wide? Hook unavailable → spin under as their default response.
- Foot in close? Hook available.
Mix all of these. With them all in your game, 50/50 from the bottom is an effective sweeping position.
Part III — Top 50/50: positioning and counter heel hooks
20. Coming up on top: foot placement and safe sit-back
53:35–55:01 · ▶ Watch
Coming up on top in 50/50 isn't common but happens — in points contexts, take it. But it carries heel-hook risk.
Foot placement
Keep the foot low, near the ribs. If partner digs to catch it, they have to pull it high to lock — gives you reaction time. If the foot is high already, any off-balance instantly catches.
Hold the knee up
If partner's knee is trapped and they can't free it, spinning under (their attack on you) is much harder. Hold the knee up to block this.
Safe sit-back
Never sit straight back down from the top — there's an immediate leg attack. Always:
- Feet together first.
- Left leg shoots through.
- Then sit back, into 50/50 in a safe way.
The sequence: foot through, then settle.
21. Counter heel hook battles: belly down wins
55:01–57:15 · ▶ Watch
If partner pulls their knee through deep and inverts, you can sometimes catch them — the inversion exposes the heel.
If they keep the foot low while inverting, the heel is too low for you to catch — so pull the knee through first.
The shared-catch scenario
Both players have heel hooks. Who wins?
- Belly-down wins. Belly-down heel hook is stronger than supine.
- If you catch and start to fall, come across to belly-down as you fall.
- Conversely, if you fall the wrong way, partner gets the belly-down position and beats yours.
Protection during this exchange
- Cross your feet as soon as possible.
- Hide your foot.
- In the worst case where they do catch you — you're still in better position (belly-down).
The strategic point: when going for the heel from top 50/50, the fall trajectory matters as much as the catch. Plan to land belly-down.
Part IV — Disengaging from top 50/50
22. Three options for disengaging: overview
57:15–58:36 · ▶ Watch
Coming up to top means accepting some risk of falling back through. If you want to keep top position without getting swept back, three options:
- Take your leg to the other side — becomes a leg drag → pass.
- Untangle partner's legs — open the gap, clear yourself out of being inside 50/50.
- Pry your leg free — wedge with the other leg, retract.
Each gets detailed.
23. Option 1: Take the leg to the far side
58:36–1:02:42 · ▶ Watch
Take your trapped leg across to the far side — leg drag or outside ashi position.
The counterintuitive posture
If you face partner and obviously prepare to take the leg, partner will defend it 100% of the time. The fix: face away. Turn 90° to partner. Now they don't read the move, and you get better positioning.
Pin the hand first
Walk your foot up; pin partner's wrist if you can. Now they can't grab to defend.
The arc
Don't try to pop the leg straight over. Partner has both arms and legs ready to block. Do the widest swing possible — kick forward, up, and across. Even if partner just catches with their elbow, you've failed.
You have to get the leg really far and back for it to clear all defenses.
What to aim for
Take partner as far onto their side as possible. Knee out to the side, not close to the hip. Don't try to land in tight leg-drag immediately — partner catches the leg under-hook if you try.
The shoulder pin
As you turn, keep your shoulder down on the knee — blocks partner from freeing the knee while you swing.
After landing
- Expect partner to reach for the underhook.
- Get a good underhook of your own; head on the right side of partner's head.
- Drive the foot back, sprawl out — strong pass position.
Often the underhook isn't clean — too tight or too late. Cross-face instead, drive weight toward the head, hips back, trawl the leg back. Usually mid-move, partner stretches to chase your leg — gives you a better underhook.
24. Option 2: Untangle partner's legs
1:02:42–1:08:00 · ▶ Watch
Get out by opening partner's lock instead of moving your own leg.
The setup
- Stand up.
- Thread your foot deep underneath partner — under their back, not just stepped near them. Stepped position lets them spin under.
- Wide base.
Posture and clearance
- Posture up. If you lean forward, partner can stop you. Posture up to unlock partner's legs.
- Hips forward. Hips back = stuck. Hips forward = free to peel.
- Push behind partner's heel; reach under; peel across.
Goal
Take partner's foot between your legs.
The big risk: invert counter
When you've opened the lock and have one foot exposed, partner can invert through and catch your knee line. Especially the heel.
Block the invert
- Block partner's leg.
- Point your knee out (not forward).
- Keep your shin attached to partner's thigh.
Knee forward = partner spins under easily. Knee out = blocks the spin.
Pass clean
- Push partner's leg.
- Come through across the leg, not at the knee — at the knee, partner inverts through.
- Use your hand to push partner's knee/feet down, away from their chest — partner can't invert if hips/knees go away from chest.
- Knee out, down across the leg. Pass to the side.
Don't go to knee-right
When passing here, don't stop in knee-right position — that creates an easy 50/50 entry back for partner. At least spin through. Block top of partner's leg, turn knee out, prevent re-entry.
If you must knee-right, have pressure with the foot back against partner's thigh; otherwise inversion catches.
25. Option 3: Pry the leg free with the shin jam
1:08:00–1:10:20 · ▶ Watch
Wedge your other leg in to assist freeing the trapped leg.
Mechanic
- Straight leg first — partner has trouble stopping you from bringing the knee.
- Lift hips up, jam your whole shin across both of partner's legs.
- Straighten the right leg.
- Push with the left shin while retracting the right foot.
- Push-pull frees the leg.
Don't scramble
Don't let it become a scramble where both could get up. As you retract, keep partner's grip and stay on your left hip. You should always win the get-up battle from there.
Difficulty hierarchy
The most basic disengage to learn first: kick the leg across (Option 1). Second: pry the legs free (Option 3). Third: more advanced grips like the Gianni Grippo variant.
For tall players: prying the legs (standing variant) works better — wide step easier to clear. For shorter players: taking the leg to the far side works better.
26. The Gianni Grippo grip variant
1:10:20–1:11:48 · ▶ Watch
An alternative grip — reach under your own leg and grab partner's far hip. Lachlan first saw it from Gianni Grippo.
What to watch for
- Partner may go for an armbar. Keep the grip tight. If they catch your hand, free it then come back.
- If you keep it tight, hard for partner to disengage the grip.
- The grip lets you turn away.
What it sets up
This isn't just a control grip — it's a back-take setup. Get your knee past the line of partner's hips. Partner reaches for the leg thinking it's free; that misdirection leaves their back exposed.
As your knee comes across, point left knee up. Wedge it in. Lifts partner's hips, exposes the back. Take the back.
Part V — Top 50/50: back-take and knee bar
27. The opportunist back-take from disengage
1:11:48–1:15:37 · ▶ Watch
The Gianni Grippo grip leads naturally to a back-take. Detailed mechanics.
Setup
- Grip the thigh from underneath.
- Scoot in close.
- Get the left knee as a wedge against partner's knee.
- Kick your leg up.
The turn-over
This is different from earlier back-takes — sometimes the hips just go up. Stack partner slightly. Drop into the wedge.
Wedge requirements
- Left knee real tight against the hip.
- Right foot back-heeling in front of partner's knee — not below the knee. Below the knee, the knee frees, the hip frees.
- Has to be back-heel at the knee.
Block the hip
Right arm holds partner's hip — blocks the hip out as you bring your knee around. Even when your knee blocks the hip, the arm makes it more secure.
Take the back
- Knee under partner's back, the further the better.
- Sit and point the foot — the John Wayne sweep — take partner this way.
- Heel right to your butt.
- Sit; partner's hips roll over; back exposed.
The grip pulls partner not straight back but at an angle — they roll over their hips rather than falling away.
28. The knee bar finish from top 50/50
1:15:37–1:21:08 · ▶ Watch
The submission option from top 50/50.
The safe top position first
Turn toward the heel-hidden direction. Even if partner inverts to catch your heel, the angle makes it very hard. Foot turned, heel hidden.
Setup for the knee bar
- Knee down.
- Bring hips into partner — hips on top of partner's chest.
- Hold partner's knee.
Get partner's feet high
You don't care if their feet are locked yet — just want them high.
When partner pushes back (their natural reaction to you sitting on their chest), their legs straighten slightly. Use that moment to pull up and catch an ankle lock grip higher on partner's leg.
Get your body in the gap
The point: partner can't triangle their feet if your body is in the way. Sit higher on partner's chest.
Posting, slide hips down — get into the knee-bar position. Body fills the gap so partner can't bring feet together.
Finishing
- Ankle in the armpit.
- Bridge.
- Hip to the ground.
- Feet go together, down near the hips.
- Bridge for the finish.
Hip-hook variant
If partner turns far during your setup, the knee bar transitions into a hip hook (heel hook). If partner doesn't turn, knee bar finishes it.
Mechanical cues
- Hips on top of partner's chest, not just behind.
- Get partner's ankle to partner's head (curl them).
- As partner pushes, pull up; that gives you the high ankle lock.
- Block triangle by being in the way.
- Body in gap → triangles can't form → no defense → bridge → finish.
The push-pull cycle: partner pushes against you, you pull up; partner curls back, you pull again. Each cycle gets the ankle higher and your body deeper into the gap.

Quick recap of top 50/50.
To attack
- Hold the knee, pommel through, do grip breaks.
- Push the heel; catch the heel; pull the knee.
- Belly down finish.
Knee bar
- Knee down, pressuring in.
- As partner pushes back, pull the ankle up high.
- Hold top of knee.
- Body in the way to block triangle.
- Roll through for the knee bar (or hip hook if partner turned).
Escapes (to get back to top safely)
- Pin the arm, turn, kick up and across, head to side, underhook.
- Bend the hand through, turn, knee behind hips/under back, John Wayne switch toward the back.
- Unpeel the legs: posture up, foot under, hips forward, open legs, pass around.
- Or jam the shin behind the back, push-pull, retract leg, come up on top.

High Percentage Leg Locks — Volume 03: Other Submissions, Outside Sankaku, Reclaiming the Knee Line, and Distal Control
Lachlan Giles closes out the main leg-lock content with four chapters — the secondary submissions worth knowing (bread cutter, toe hold, straight ankle from 50/50), outside Sankaku in depth (including a recent Vettelina-inspired forward-roll finish he calls possibly the best way to catch the heel from there), how to reclaim the knee line once partner has freed it, and the full distal control system for when you only have the end of the leg.
High Percentage Leg Locks — Volume 05: Defending the Saddle and Outside Ashi, and Inside-Position Entries to 50/50
Lachlan Giles flips the perspective — first teaching how to defend the saddle (all its attack variants, the leg lace, double trouble, the Z lock) and outside Ashi (including last-resort heel-hook escapes), then how to enter 50/50 and outside Sankaku from the inside-position guards (butterfly, half butterfly, shin-to-shin, single leg X) with the full menu of follow-ups: outside Sankaku via sweep, outside Ashi, X-guard, K-guard, and the reverse-X saddle entry.
