Now you are both standing exactly where you started, except you are tired, slightly turned, and fresh out of ideas. So you reset. You re-grip. You try the same throw again, a little harder, and it fails the same way, a little worse. By the third try the round feels rigged. It is not rigged. It is unfinished. Your first attack did its job and you threw the job away.
Beginners are taught throws as single events. Grip, break balance, enter, throw. That model is fine for learning mechanics and useless for live judo, because a live partner's whole job is to make the single event fail. What experienced players know, and what rarely gets said plainly, is that the first attack is often the question, not the answer. The answer is whatever your partner's body does next.
Section 01Why Singles Die
A single attack asks your partner to cooperate with a plan they can see coming. They have one problem to solve, and solving it is usually easy: step off, block with the hip, straighten up, lean back, turn out. Any one of those is enough against a lone technique.
Two attacks linked together ask them to solve two problems with one body, and the solutions fight each other. The step that escapes your first throw loads the leg your second throw reaps. The lean that blocks your forward throw is the kuzushi (balance breaking) for your backward throw. This is renraku-waza, combination technique, and it is not advanced decoration on basic judo. It is basic judo, played at the speed real people move.
Kaeshi-waza, counter technique, is the same logic from the other side. When they attack you, they have committed their weight, their direction, and at least one leg. That commitment is information and opportunity at once. The counter player is not luckier than the combination player. They are reading the same book from the other end: a real attack always moves weight somewhere, and weight that has moved can be used.
Section 02The Logic: Their Reaction Is the Opening
A real first attack draws a real reaction. A fake one draws nothing, and that is the first hard truth of combinations. If your opening technique does not genuinely threaten to throw them, they do not have to react, and your combination is two weak techniques holding hands.
When the first attack is real, partners react in a small set of predictable ways. Learn the set and you are no longer improvising. You are answering.
| Their reaction | What their weight did | What it opens |
|---|---|---|
| Steps off or around your entry | Weight lands on the stepping leg, their line changes | Sweep or reap the landing leg; attack the new angle |
| Leans back, hips away | Weight goes to their heels, posture straightens behind them | Backward throws: reaps and trips behind the loaded heels |
| Bends forward, pushes back at you | Weight drives forward into you, head and shoulders lead | Forward throws under the drive, drop techniques, forward sweeps |
| Blocks with the hip and turns out | One hip commits, the far leg lightens | Change direction across their body; attack the light side |
| Stiffens and roots both feet | Weight drops straight down, nothing moves | Move them again with ashi-waza (foot techniques) and grip pressure rather than a bigger throw |
Read the table as a loop. Attack, read, answer, and if the answer draws its own reaction, answer that too. Most club combinations are two techniques long. Good ones are three. Nobody at your level needs five, and a rehearsed five usually means the first four were not real.
Section 03The Classic Families
Combinations are taught in families because families share a first attack and branch on the reaction. Learn two or three pairs cold rather than twenty pairs vaguely.
Forward to forward. Your forward throw is blocked but their weight is still coming at you or they have stepped to a new angle in front of you, so you throw forward again from the new geometry. Ko-uchi-gari (minor inner reap) into seoi-nage is the teaching classic: your reap inside forces them to step and straighten, and as their weight settles forward over the defending leg, your turn into the shoulder throw is already lined up. Seoi-nage into a second forward technique, such as another seoi entry to the other side or a tai-otoshi (body drop) across their step-off, belongs to the same family. The engine is their recovery step. You are not restarting the attack. You are meeting it.
Forward to backward. This is the family beginners need most, because the natural block to a forward throw is to lean away from it, and leaning away loads the heels behind them. Osoto-gari (major outer reap) into sasae-tsurikomi-ashi (propping and drawing ankle throw) runs the logic in reverse and shows the hinge clearly, but the standard teaching pairs are these: attack the forward throw, feel them sit back and straighten, then take the weight they just parked: o-uchi-gari (major inner reap) or ko-uchi-gari behind the loaded legs, or osoto-gari itself as the second technique once their posture is upright and their heels are heavy. O-uchi-gari into tai-otoshi deserves its own mention because it crosses the family line in practice: the reap forces a wide step and a forward recovery, and tai-otoshi waits across that recovery. Schools name the families slightly differently, and some teach osoto-gari into sasae as a forward-to-forward change of angle rather than a change of direction. The names vary. The mechanics do not: their defense told you where their weight went, and you went there.
Big throw to ashi-waza, and back. Foot techniques are the connective tissue of combinations. They cost little, they fail safely, and every attempt moves their feet, which is information. A heavy forward attack that they hop out of leaves a landing foot asking to be swept with deashi-harai (advanced foot sweep). An ashi-waza attempt they pull away from straightens them up for the big throw. Experienced players often run this as a rhythm rather than a plan: sweep, sweep, big throw on the third beat, when their feet have stopped traveling freely because they are watching yours.
The named pairs to start with. If your club has no set list, this starter set covers every family honestly:
| First attack | Their likely reaction | Second technique |
|---|---|---|
| O-uchi-gari | Wide step out, weight forward on recovery | Tai-otoshi |
| Ko-uchi-gari | Steps back, straightens over their heels | Seoi-nage on their forward recovery, or osoto-gari if they stay parked back |
| Osoto-gari | Hops or steps across, posture uprights | Sasae-tsurikomi-ashi against the landing/support leg |
| Seoi-nage | Leans back, hips away | Ko-uchi-gari or o-uchi-gari behind the loaded heels |
| Uchi-mata (inner thigh throw) | Hops around, weight crosses their body | Ko-uchi-gari or a second uchi-mata to the changed angle |
| Deashi-harai | Pulls the swept foot back, shifts weight | The big forward throw their shift just loaded |
Treat the table as a map, not a script. Your coach may teach different pairs, often built around the throws you already own. That is right, not wrong. A combination only exists if both of its techniques are individually real for you.
Section 04Counters: Their Attack Is Information Too
A counter is not a trick you keep in a pocket. It is a combination where they supply the first technique.
The counter mindset has three parts. First, survive the entry without giving ground in a straight line, because most throws need your weight moving the way they planned. A small angle step ruins more attacks than any block. Second, read what their attack spent: which leg is committed, which way their weight is traveling, what their hips are doing. Third, spend it for them. If their reap is passing your leg, your own reap on their standing leg is already half set up. If their forward throw has turned in and stalled, your weight settling behind them is a backward counter waiting for a leg to finish it. Classic counters every player should recognize include osoto-gaeshi (major outer reap counter) against osoto-gari, uchi-mata-sukashi (inner thigh slip) against uchi-mata, tani-otoshi against forward turn throws where your club's rules allow it, and the simple, underrated counter of stepping off and sweeping the support leg as their technique passes.
Two cautions, both important. Counters that drop your weight across a partner's planted knee, above all tani-otoshi thrown carelessly, can injure the very leg their weight is standing on. Learn them with a coach, at practice speed, with control of their fall. And a counter you go hunting for is just a plan to stand still and wait, which referees and good partners both punish. Defend actively, attack your own attacks, and take counters as they present themselves.
Section 05Building the Second Act in Practice
You do not build combinations in free randori first. You build them in order:
- Uchikomi with the reaction. Your partner gives the real defensive reaction, not a statue impression, and you practice only the switch, slowly, until the second entry feels like one movement.
- Nage-komi chains. Full throws, both techniques, against a partner who defends the first honestly and takes the second fall when you earn it.
- One-attack randori. Rounds where every attack must have a second technique attempted. The second can fail. What is not allowed is the reset.
- Free randori with a tally. Count your second attacks, not your throws. The count is the behavior you are installing.
Expect a messy month. Your first attacks will get temporarily worse because part of your mind is already on the second. That passes, and what replaces it is the first real version of your judo.
Section 06Where It Goes Wrong
The fake first attack. Tapping at them with a half-turn to trigger the combination is the most common failure, and partners smell it at once. No threat, no reaction, no combination. Commit the first technique like you mean to finish with it, because sometimes you will.
Pre-deciding the second throw. Running pair number three regardless of what they did turns a combination into a longer single attack. The reaction chooses the second technique. Your job is to have rehearsed the two or three answers their likely reactions need.
Resetting to your comfort grip after every failure. The reset hands them back all the ground your attack won. Stay in, keep a hand working, attack off the position the failed throw left you in. Combinations live in the half second after a technique fails, not in a fresh start ten seconds later.
Treating counters as your whole game. A player who only waits is donating the initiative and, in competition, donating the referee's story. Counters complete an attacking game. They never replace one.
Learning pairs your first technique cannot support. If your o-uchi-gari does not move anybody yet, o-uchi into tai-otoshi is calligraphy, not judo. Fix the single, then chain it.
Section 07The Companion Guide
This article gives you the knowledge. The companion guide turns it into training. The Combination and Counter Playbook lists the core combination pairs as full drill cards, each with the entry counts, the exact defensive reaction your partner feeds, and the switch mechanics to rehearse. It maps the four common reactions to a counter menu with safety notes on the dangerous ones, lays out a six-week build from uchikomi (repetition entry practice) through one-attack randori, and includes tracking sheets for second-attack counts, pair success rates, and counter reads in live rounds.
It is made for the single-attack player whose best throw works in practice and vanishes in randori, and for pairs of training partners who want to feed each other honestly instead of trading statues.
- A real first attack draws a real reaction, and the reaction, not the plan, chooses the second technique.
- Combinations run in families: forward to forward, forward to backward, and big throw to ashi-waza and back.
- Start with a few named pairs you can actually throw: o-uchi-gari into tai-otoshi, ko-uchi-gari into seoi-nage, osoto-gari into sasae-tsurikomi-ashi.
- Counters are the same logic reversed. Their attack spends their weight and a leg, and that spending is your opening.
- Never hunt counters and never fake the first attack. Both turn live judo back into a script partners can read.
- Build chains in order: reacted uchikomi, nage-komi chains, one-attack randori, then free randori with a second-attack tally.
