ADCC championship rules allow a wider submission catalog than IBJJF belt divisions, so beginners need a clear legality map before changing their game.
ADCC-style competition rewards submission hunting and opens the legal catalog earlier than IBJJF belt divisions.
Official ADCC Championship rules — published on the ADCC rules page — list any choke except using the hand to close the windpipe, any arm bar, shoulder lock, or wrist lock, and any leg lock or ankle lock. They also list the can opener and twister as allowed.
That catalog is much wider than the IBJJF Illegal Moves table for lower belts. Legal does not mean mandatory. Beginners should still build a base of chokes, arm locks, and positional control before adding high-risk finishes.
These are the techniques beginners ask about most when comparing the two official rulesets.
- Heel hook — IBJJF illegal except adult brown/black no-gi; ADCC legal
- Toe hold — IBJJF illegal through purple; ADCC legal
- Wrist lock — IBJJF illegal at white belt; ADCC legal
- Knee bar — IBJJF brown/black only; ADCC legal
- Calf slicer — IBJJF brown/black only; ADCC legal
- Bicep slicer — IBJJF brown/black only; ADCC legal
Can opener and twister
ADCC championship rules list both as allowed. The same page bans neck cranks that trap both shoulders with downward pressure. Do not assume every neck or spinal crank is free just because the event is no-gi.
Event rules still win
Qualification rounds, local ADCC-rules events, and age divisions can add their own limits. Read the packet for your bracket.
Keep rear naked chokes, armbars, triangles, and straight ankle locks as your training foundation. Then study heel-hook and compression entries as control problems with slow pressure and clear tapping agreements.
If you compete IBJJF soon, keep restricted finishes out of your competition muscle memory. If you compete under ADCC-style rules, ask your coach which newly legal attacks are appropriate for your experience level.
Key Takeaways
- ADCC championship rules allow any arm lock and any leg lock, plus the can opener and twister.
- Many of those finishes stay illegal for lower belts under the IBJJF Illegal Moves table.
- Beginners should learn the legality map before adding high-risk finishes.
