Semi-Free Sparring (Ban-Jayoo Matsogi)
Semi-free sparring is the bridge between step sparring and free sparring. It adds decision-making — but keeps safety and learning high by limiting options. This is where students learn to choose the right tool at the right moment.
What semi-free sparring solves
Step sparring builds structure, but it’s predictable. Free sparring requires choices under pressure. Semi-free sparring fills the gap.
- Decision-making: students learn to choose, not just repeat.
- Timing under mild pressure: still controlled, but less scripted.
- Distance discipline: entries and exits become intentional.
- Safety: limited tools reduce chaos while skill increases.
- Confidence: students learn “real sparring skills” without overwhelm.
Core idea: controlled freedom
“Semi-free” means the student has choices — but not unlimited choices. It should feel like sparring, while still being teachable.
- Not scripted: partners don’t announce or pre-plan.
- Not chaotic: techniques are limited by rules.
- Not about winning: it’s a learning tool.

Recommended rulesets (pick one)
The fastest way to make semi-free work is to choose a rule set and run it consistently for 2–4 weeks. Here are common, high-value options:
Ruleset A: Limited attacks (beginner semi-free)
- Allowed attacks: 2–3 options (example: lead punch, reverse punch, front kick).
- Allowed counters: 2–3 options (example: side step + counter, stop-hit, after-counter).
- Goal: learn distance and timing without overwhelm.
Ruleset B: One attack at a time (A attacks, B responds)
- A attacks once, B defends/counters once.
- Reset and switch roles after a set.
- Goal: clean decision-making and calm control.
Ruleset C: Score then exit
- After any clean touch, both partners must exit and reset.
- Goal: remove brawling and teach discipline.
Ruleset D: Angles required
- Every entry must include a small angle step (not straight-line charging).
- Goal: teach centerline awareness and safer positioning.
Instructor tip: if it gets messy, reduce options. Semi-free should feel clean.
Teaching progression
Semi-free sparring becomes safe and effective when taught in layers.
Level 1: One tool only
- Only lead hand touch (or only front kick) is allowed.
- Goal: distance and entry timing.
Level 2: Two tools
- Add one more attack option (e.g., lead punch + rear punch).
- Goal: simple choices.
Level 3: Add a counter rule
- Require a specific counter type (stop-hit or after-counter).
- Goal: teach timing windows.
Level 4: Add limited combinations (advanced)
- Allow only 2-technique combinations (e.g., punch → punch, kick → punch).
- Rule: no flurries.
Level 5: Add controlled pressure (advanced)
- Increase speed, not power.
- Goal: composure and clean execution.
What to coach (priority order)
- Control gate: stop command, safe contact, emotional control.
- Distance: no reaching, no crowding.
- Footwork: enter/exit cleanly; no crossing feet.
- Timing: choose before/during/after.
- Guard recovery: hands return after every technique.
Teaching shortcut: “Score and leave” fixes most problems.
Common mistakes (and fixes)
Mistake: Semi-free turns into free sparring
- Looks like: too many techniques, too much chasing.
- Cause: no clear ruleset or weak enforcement.
- Fix: reduce options; add reset rules; stop rounds early.
Mistake: Students “spam” one technique
- Cause: fear or lack of tools.
- Fix: require alternating tools or “must use both sides.”
Mistake: Backing up forever
- Cause: no angle habits.
- Fix: require side-step/pivot as reset after each exchange.
Mistake: Leaning for range
- Cause: poor distance judgment.
- Fix: teach entry step; mark distance; enforce no-lean rule.
Mistake: Hands drop after attacking
- Cause: excitement, “admiring the hit.”
- Fix: “guard reset” requirement before moving again.
High-value drills
1) Two-tool semi-free rounds
- Only two attack options are allowed.
- Round is 30–60 seconds.
- Goal: decisions without chaos.
2) Score-and-exit drill
- After any clean touch, both partners must step out and reset.
- Goal: teach discipline and reduce brawling.
3) Angle-only entry drill
- Attacks must enter at a slight angle (no straight charging).
- Goal: safer positioning and better openings.
4) Timing window drill
- Pick one timing window for the round: before, during, or after.
- Goal: teach timing awareness instead of random exchanges.
5) Guard reset habit
- After every attack, students must return to guard immediately.
- Goal: eliminate the “hands drop” habit.
Quick instructor checklist
- Rules are clear: students can state the allowed attacks/counters.
- Options are limited: fewer tools = cleaner learning.
- Control is enforced: stop early, reset often.
- Distance is honest: no leaning, no crowding.
- Exit exists: students disengage instead of chasing.
