Half Guard to Demi Guard establishes a gi lapel guard by arranging collar control, the lapel behind the passer’s knee, and a foot on its tail while keeping the legs in front.
This is a proposed connection from an ordinary half-guard leg trap into the published Demi configuration. It requires room to change the legs and access to the lapel; a flattened, chest-to-chest half guard does not supply that room automatically. From Half Guard bottom, first preserve frames and a facing angle before exchanging the leg trap for foot-on-lapel control.
The destination is established only when the collar, knee-line lapel and foot work together. If the feed fails, retain a usable guard instead of holding loose fabric while the opponent clears your legs. The configuration is described in Legion’s dictionary; Keenan’s introduction explains its response to forward pressure.

Playing as Attacker
Key Principles
-
Keep the legs in front during the grip change.
-
Arrange the collar control before relying on the lapel barrier.
-
Route the lapel behind the knee without twisting the joint.
-
Confirm foot contact on the tail before calling the entry complete.
-
Retain the starting guard when the feed cannot be completed.

Common Mistakes
-
Releasing every starting control at once
- Consequence: The passer can advance through the unprotected space.
- Correction: Transfer one connection at a time while keeping the leg barrier.
-
Feeding cloth while your knees are already passed
- Consequence: The collar and lapel cannot replace missing guard frames.
- Correction: Recover your legs before attempting this entry.
-
Placing the foot on slack fabric
- Consequence: The foot has no useful connection to the opponent’s knee.
- Correction: Recheck the lapel path and remove only enough slack to make contact work.
Playing as Defender
Key Principles
-
Recognize the change of collar, lapel and foot controls early.
-
Keep a usable base or leg barrier while contesting the movement.
-
Choose a response that fits the current controls rather than a lost grip.
-
Release any connection that binds a knee during movement.
-
Identify the resulting position before continuing the exchange.
Recognition Cues
-
The guard player takes or adjusts a collar grip.
-
The lapel is being guided behind your knee.
-
A foot approaches the lapel tail as the knees remain between you.
Defensive Options
-
Contest the feed while preserving base - When: Before the lapel reaches a useful position behind your knee
-
Prevent the foot from settling on the tail - When: During the change of leg position
-
Clear the legs during an abandoned feed - When: Only when the guard player has lost both the lapel connection and the leg barrier
