Most grapplers treat half guard and butterfly guard as separate rooms. Adam Wardzinski knocked out the wall between them. His butterfly half guard keeps one hook loaded while a half-guard frame kills the crossface — the hybrid that carried a Polish heavyweight from outside the map to a black-belt Worlds title and an IBJJF Grand Slam.
By the late 2010s, the received wisdom about butterfly guard at the highest levels was that it had aged out. The elevator sweep that Marcelo Garcia had used to embarrass the heaviest men in the sport a decade earlier was, the argument went, a lightweight's toy — too open, too dependent on a scramble, too easily flattened by a modern heavyweight who simply drove his hips down and passed. The best guards of the era were leg-lock entries and lapel tangles. Butterfly was a museum piece.
Then a heavyweight from Zabrze, in southern Poland, started winning off it — not by out-athleting people, but by refusing to let them flatten him in the first place. When an opponent dropped his weight to smother the butterfly hook, Adam Wardzinski did not fight to keep both hooks in. He gave one up on purpose, slid that leg into half guard, framed off the crossface, and kept the other hook alive underneath the tangle. From there the sweep was still there, the same elevator, but now it was launched from a base that could not be simply pressured flat. He was, in effect, guarding with a half-guard leg and attacking with a butterfly leg at the same time.
That refusal — to pick between the two guards, to instead run them at once — is the whole system. It is why a competitor from a country with no BJJ pedigree to speak of, who did not receive his black belt until October 2016, spent the back half of his career funneling the best heavyweights in the world into a position they knew was coming and could not stop. Opponents scouted the butterfly half guard for years. Most of them still ended up on their backs.
This is not a story about butterfly guard being reborn. It is a story about the seam between two guards, and the man who learned to live in it.
The butterfly half guard is not butterfly guard with a half-guard escape hatch, nor half guard with a butterfly wrinkle — it is a single position in which one leg guards and one leg attacks, so that the pressure that beats each guard alone has nothing to beat.
Adam Wardzinski was born on 22 April 1991, and he is Polish, which for most of BJJ's history would have been the end of any competitive story. Brazilian jiu-jitsu had no meaningful foothold in Poland when he began; there was no local black-belt tree to climb, no domestic circuit that produced world champions. He trained under Alan "Finfou" do Nascimento — a Brazilian black belt of the Checkmat lineage — and received his own black belt from Nascimento in October 2016. He would represent Checkmat for the rest of his career.
What Wardzinski lacked in national pedigree he made up for in specialization. Rather than assembling the fashionable modern toolkit, he went deep on one of the oldest guards in the sport and asked a narrower question than anyone else was asking: not "how do I sweep from butterfly," but "what do I do at the exact instant butterfly fails." The honest answer, for most players, is that they scramble or lose the position. Wardzinski's answer was to have already been in half guard the whole time.
The codification came through BJJ Fanatics, the sport's dominant instructional publisher, where Wardzinski released a run of butterfly-centred titles. The Butterfly Guard Re-Discovered series — including the updated 3.0 edition and a dedicated no-gi release, The No Gi Butterfly Guard Rediscovered — laid out the funnel logic of his whole butterfly game and carved out sections for its sub-variants: side butterfly, "lazy" butterfly, and the half butterfly. The hybrid then got its own standalone treatment in Half Butterfly: Victory Blueprint, a six-volume gi instructional that frames the half butterfly not as a defensive fallback but, in the product's own words, as "a central hub for sweeps and transitions." That is the codification test met on the record: a discrete, named position, taught as a system rather than a trick, by the athlete who made it his signature.
The word "rediscovered" in those titles is doing real work. Wardzinski has been consistent in public that he did not invent butterfly guard — nobody sane claims to. What he claims, and what the instructionals actually teach, is a re-engineering of an old position's failure point. The half-butterfly seam is the part earlier butterfly players treated as a leak. Wardzinski treated it as the plumbing.
Butterfly guard, in its classic form, is a two-hook position: the bottom player sits up, threads both insteps under the opponent's thighs, and uses those hooks as elevators to off-balance and sweep. Its historic weakness is posture and pressure. If the top player flattens the bottom player onto his back and drives a crossface across the jaw, the sit-up disappears, the hooks lose their lifting angle, and the guard dies. Everything downstream of that flattening — the pass, the score, the loss — follows from one moment of lost posture.
The butterfly half guard removes that moment. It does so by conceding half of the classic structure before the opponent can take it.
One leg guards, one leg attacks. In the hybrid, the bottom player keeps a single live butterfly hook on one side — the attacking leg — while the other leg slides underneath the opponent's near leg into a half-guard entanglement. That half-guard leg is not there to sweep. It is there to occupy the top player's base, deny the flattening drive, and buy the framing space that keeps the sit-up intact on the other side. The result is a base that is much harder to press flat than open butterfly, because a knee and shin are wedged into the very hip the passer needs to drop.
The far-side sleeve is the constant. Across Wardzinski's butterfly game, the technical anchor is a far-side sleeve or wrist grip. It prevents the crossface — the single most important defensive job in the whole position — and it feeds directly into the finish, because the arm it controls is the arm the opponent would otherwise post with to stop the sweep. In the half-butterfly specifically, this grip is what lets the bottom player stay on his side rather than getting rolled to flat, which is the difference between the hybrid and a plain half guard being smashed.
Grounding the knee. One of the signature mechanical details is how Wardzinski neutralizes a tall, posturing passer. Rather than fighting the height, he removes his top leg from the tangle and crosses his own instep against the opponent's instep, using it to push the top player's knee down to the mat. Flattening the passer's knee shortens his base and drops his hips into range, at which point the loaded butterfly hook has the angle it needs again. It is a small, unglamorous adjustment, and it is the kind of thing that separates a system from a highlight.
The funnel. The strategic spine, which FloGrappling has described as a deliberate "funnel," is that the hybrid does not offer opponents a clean way out. Standard butterfly gives the top player a binary: pass low and get elevated, or stand and get taken down. The half-butterfly adds a third layer — the half-guard leg — so that the passer's usual escape from butterfly (flatten and crossface) is itself walled off. Every route the top player takes to solve one leg exposes him to the other. Push the knee to the mat and you feed the far hook; posture up and you feed the half-guard hook and the back; drive the crossface and the sleeve grip has already killed it.
The exits, all forward. The hybrid is a hub, not a terminus. From it, Wardzinski's material chains into full butterfly when the opponent gives him the second hook back, into X-guard and single-leg-X when the opponent stands, and into straightforward top position when the elevator sweep lands. The half-guard leg also keeps the classic half-guard back-take live — when the passer over-commits his weight forward, the underhook-and-come-up route to the back is right there. The point the instructionals press is that none of these are separate games to memorize. They are the same position resolving in whichever direction the opponent chooses to be wrong.
What a section in a generic half guard or butterfly guard article cannot say is exactly this simultaneity. Half guard, taught on its own, is a recovery and underhook-battle position; butterfly, taught on its own, is a sit-up-and-elevate position. The butterfly half guard is neither, because it is both at once, and the whole value is that the counters to each are mutually exclusive. You cannot flatten a man who is already using half of his structure to prevent flattening, while the other half keeps attacking. That is the non-derivative core, and it is why the position earns its own name rather than a footnote in either parent.
By the 2020s, Wardzinski was not a curiosity but a fixture at the top of the heavyweight (-94 kg) division, and the butterfly half guard had gone from personal quirk to widely scouted, widely imitated game plan. Opponents knew the funnel was coming. FloGrappling ran explainers on how he pulled the best in the world into it anyway. The instructional sales followed the results, which is the market's crude but honest signal that the system works for people who are not Adam Wardzinski.
The spread was helped by timing. The 2018–2022 stretch saw a broad revival of butterfly and hook-based sweeping at the elite level, partly as a gi-friendly counter to the leg-lock and lapel arms race, and Wardzinski was the most visible heavyweight driving it. One striking figure has circulated in coverage and promotional material — that a very large share of the hook sweeps recorded at IBJJF Worlds across those years belonged to him alone. The number is memorable and directionally consistent with how dominant his sweeping was, but the precise percentage traces to promotional framing rather than a published IBJJF dataset, and it is flagged below rather than asserted here as fact.
What did not change across the era is the position's core dependence on grip and frame over athleticism. Wardzinski's butterfly half guard aged well precisely because it was never an athletic-window game. It is a leverage-and-timing game — "precision, timing, and efficiency, not strength," as the Half Butterfly material puts it — which is exactly the kind of system that stays viable as its author gets older and as the division around him gets bigger and more explosive. He retired at the 2025 IBJJF World Championship, on top, rather than being pushed out by the next athletic wave.
A short, dated list of moments where the butterfly and its half-guard hybrid carried Wardzinski at the sport's top level. Where a specific score is not confirmed against a scoresheet, that is noted.
Wardzinski won the no-gi world title at black belt, the achievement widely reported as making him the first male European to become a black-belt IBJJF World Champion. His run was defined by lopsided sweeping — one report noted he posted the single biggest points differential of the day — including a clean butterfly sweep en route. The final itself was an all-Checkmat closeout with teammate Jackson Sousa rather than a contested match, a detail worth keeping straight: the title was real and decisive, but the gold-medal bout was not fought.
Gold, over a field that included Fellipe Andrew, a marquee heavyweight of the era. The European crown was part of the sustained gi run that established Wardzinski as the division's steadiest sweeper. (Exact final scoreline pending scoresheet verification.)
In IBJJF's invitational super-event, Wardzinski beat two-time World Champion Gustavo Batista by a single advantage, 1–0, scored inside the final two minutes of a ten-minute bout — a tight, grip-fought win that capped a strong year and showcased the funnel's patience against an elite passer.
Back-to-back black-belt gi world titles at heavyweight. The 2025 title came in his retirement appearance and, in the same season, completed the IBJJF Grand Slam — European, Brazilian Nationals, Pan, and Worlds gold in a single year — reported as a first for a European competitor. (Individual match scores across these brackets are pending scoresheet verification and are not asserted here.)
White belt should not be building a butterfly half guard yet — they should be learning to sit up in classic butterfly and keep their back off the mat. The one lesson that matters at this stage is that the position dies the instant you get flattened, so the whole job is posture and the sit-up. Everything Wardzinski does later is a solution to a problem you cannot yet feel.
Blue belt meets the seam for the first time, usually by accident: the top player flattens the butterfly and the blue belt's leg naturally slides into half guard as a panic recovery. The shift into blue-belt understanding is realizing that this "failure" is the entry to the hybrid, not the end of the sequence — and that the far-side sleeve grip, not strength, is what keeps you on your side.
Purple belt starts running the funnel on purpose. The purple belt no longer waits to be flattened; he offers the half-guard leg deliberately, keeps one hook loaded, and learns that the opponent's escape from one leg is the attack on the other. This is where the position stops being defense and becomes a hub.
Brown belt learns the knee-grounding detail and the transitions out — half-butterfly to full butterfly, to X-guard, to single-leg-X, to the back — as one connected map rather than separate techniques. The brown belt can steer which exit fires by controlling which mistake he lets the opponent make.
Black belt does what Wardzinski does: makes the position a destination he funnels the whole match toward, against opponents who have scouted it, and wins anyway because the counters are mutually exclusive and he is better at the grip fight than they are at escaping it.
Coral belt can teach why the two guards' weaknesses cancel, and can explain — without notes — exactly which grip prevents which pass and which exit answers which escape.
1. Treating the half-guard leg as a sweep, not a frame. The most common error in learning the hybrid is trying to sweep off the half-guard leg the way you would in a classic half-guard come-up. That leg's job is to occupy the passer's hip and prevent the flatten. The sweep comes from the butterfly hook. Ask the wrong leg to do the finishing and you get neither the frame nor the sweep.
2. Losing the far-side sleeve. Without the far-side sleeve or wrist grip, the crossface arrives, you get pressed to flat, and the hybrid collapses into a bad half guard. Wardzinski's game treats this grip as non-negotiable. If you can only keep one grip, keep this one.
3. Fighting a tall passer's height instead of grounding the knee. Beginners try to muscle a posturing, upright passer back down with their arms. The system's answer is the instep-to-instep detail that pushes the opponent's knee to the mat, shortening his base. Grounding the knee, not wrestling the shoulders, is what restores the sweep angle.
4. Keeping both hooks in and getting flattened. Refusing to give up the second hook — clinging to classic butterfly when the pressure comes — is the exact failure the hybrid exists to solve. The willingness to concede one hook into half guard before being flattened is the whole insight. Hold both and you are just playing butterfly against a heavyweight, which is the fight you were trying to avoid.
5. Treating it as a stall. The half-butterfly can look passive if you sit in it. It is a hub, and hubs are for moving through. If you are not threatening an exit — full butterfly, X-guard, the back, or the sweep — you are giving a good passer time to solve both legs at once.
Isolate the seam this week. With a same-rank partner, start flat on your back in a smashed butterfly — the worst-case moment, top player already driving a crossface. Your only job for a fifteen-minute round is to slide one leg into half guard, win the far-side sleeve grip, and get back onto your side with the other hook alive. No sweeps. No back-takes. Just recover the hybrid from the position where classic butterfly has already lost. You are drilling the concession — the deliberate trade of one hook for a frame — until it stops feeling like a defeat.
Add a second round with one attack allowed: the elevator sweep off the live hook, and only that. Your partner defends fully and is allowed to posture tall. Your job is to ground his knee with the instep-to-instep detail and finish the sweep, or reset. No X-guard, no scrambles — just the grounding detail feeding the one sweep, so the mechanic burns in.
Run both weekly for six weeks. The tell that it is working is subtle: you will stop getting flattened, and you will start noticing that opponents who solve one of your legs have just handed you the other.
The butterfly half guard sits exactly on the border between two of the sport's oldest guards, which is the point.
Every one of these was reached by someone trying to make a bottom position survive a bigger man on top. The butterfly half guard is the specific answer that refuses to choose between surviving and attacking.
