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)

  1. Control gate: stop command, safe contact, emotional control.
  2. Distance: no reaching, no crowding.
  3. Footwork: enter/exit cleanly; no crossing feet.
  4. Timing: choose before/during/after.
  5. 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.
