Complete Pass from Flattened Half Guard is the definitive guard-passing sequence executed when the top player has already collapsed the bottom player’s frames and established chest-to-chest control with one leg still trapped in the half guard hook. This transition represents the final phase of the pressure-passing sequence, where the technical challenge shifts from maintaining dominant control to extracting the trapped leg without surrendering the positional advantage that was so methodically earned. The pass completion requires a precise balance between sustaining forward pressure that keeps the bottom player pinned and creating just enough angle to free the leg through the half guard entanglement.
The strategic significance of this transition lies in its position within the passing hierarchy. By the time the top player reaches flattened half guard, they have already won the underhook battle, established the crossface, and driven the bottom player flat. Abandoning this advantage through a sloppy extraction attempt would reset the entire passing sequence, potentially returning the bottom player to an active half guard with frames and offensive options. The complete pass therefore demands that every movement preserves the pressure investment already made, treating the leg extraction as a surgical procedure performed under the cover of sustained, suffocating chest and hip pressure.
From a systems perspective, the complete pass connects the pressure-passing chain to the side control attacking platform. Successful execution opens the entire side control submission tree including Americana, Kimura, arm triangle, and positional advances to mount or knee on belly. The pass also earns three points in IBJJF competition, making it a high-value transition that combines tactical advancement with scoring opportunity. Understanding when to initiate the extraction, which angle to create, and how to maintain control throughout the movement separates practitioners who can flatten opponents from those who can actually finish the pass.

Playing as Attacker
Key Principles
-
Maintain chest-to-chest pressure throughout the entire extraction sequence - never lift your torso to free the leg
-
Create angular displacement rather than direct force to overcome the half guard hook
-
Use the crossface as an anchor point that pins your opponent while your lower body works the extraction
-
Time your extraction attempt when the opponent is focused on surviving pressure rather than actively defending the hook
-
Drive your hips forward and down during extraction to prevent space creation beneath you
-
Treat the pass completion as a continuous flow rather than a discrete step - settle into side control without pause
-
Control your opponent’s far hip with your free hand to prevent them from following your hip movement during extraction
Execution Steps
-
Consolidate upper body control: Before initiating any leg extraction, verify that your crossface is secure with your forearm driving…
-
Block the far hip: Place your free hand on your opponent’s far hip, pushing it toward the mat. This prevents them from …
-
Create the extraction angle: Shift your hips slightly toward the side of the trapped leg while maintaining chest pressure. This d…
-
Drive the knee through: With the angle established, drive your trapped knee diagonally across your opponent’s thigh, slicing…
-
Clear the foot: As your knee clears the hook, immediately pull your foot free by curling your heel toward your butto…
-
Establish hip-to-hip contact: The instant your leg is free, drive your hips into your opponent’s near hip to establish the hip-to-…

Settle into side control: Transition your crossface and upper body control into standard side control configuration. Spread yo…
Common Mistakes
-
Lifting chest to create space for leg extraction rather than maintaining pressure throughout
- Consequence: Opponent immediately inserts elbow frame or knee shield, recovering to active half guard and resetting the entire passing sequence
- Correction: Keep your chest welded to your opponent’s chest during the entire extraction. Use angular hip movement and knee slice mechanics to free the leg without any reduction in upper body pressure.
-
Attempting to yank the trapped leg straight back through direct force against the hook
- Consequence: Hook becomes tighter as your opponent clamps down reflexively, wastes significant energy, and telegraphs your passing intention giving them time to prepare defensive frames
- Correction: Create an angle with your hips first, then slice the knee diagonally across rather than pulling straight back. Angular displacement overcomes the hook through geometry, not force.
-
Neglecting to block the far hip before initiating extraction
- Consequence: Opponent shrimps toward you during the extraction, following your movement and maintaining the hook or recovering to knee shield half guard
- Correction: Always control the far hip with your free hand before beginning any extraction attempt. This pin prevents the shrimp that is their primary defensive movement.
Playing as Defender
Key Principles
-
The hook alone is a temporary barrier - use the time it buys to recover frames rather than relying on it as your sole defense
-
Fight for the underhook on the far side even while accepting the crossface, as it prevents full flattening and creates escape structure
-
Time your hip escape to coincide with the opponent’s extraction attempt when their focus is divided between pressure and leg movement
-
Keep your knees active and ready to insert as frames the moment any space appears during the extraction sequence
-
Breathe tactically with small controlled breaths timed to your micro-movements rather than fighting for deep breaths under pressure
-
Monitor the angle of your opponent’s hips as the primary indicator that an extraction attempt is beginning
Recognition Cues
-
Opponent shifts their hips to one side while maintaining chest pressure, creating a diagonal angle with their trapped leg
-
Opponent’s free hand moves to control your far hip, pinning it to prevent your shrimp
-
Opponent drives their knee forward and diagonally across your thigh rather than simply maintaining the trapped position
-
You feel a reduction in the hook’s effectiveness as the angle of the trapped leg changes relative to your grip
-
Opponent increases crossface pressure suddenly, which often precedes an extraction attempt to prevent you from reacting
Defensive Options
-
Hip escape toward the trapped leg side at the moment of extraction to recover knee shield or half guard frames - When: When you feel the opponent begin their hip shift or knee drive indicating extraction is starting, and you have enough space to shrimp
-
Clamp the hook tighter by squeezing your knees together and turning your hips to face your opponent during the extraction - When: When the opponent begins the knee slice and you need to buy time to set up a more complete defensive response
-
Insert elbow frame during the moment of extraction when the opponent’s pressure necessarily shifts - When: When the opponent lifts their chest even slightly during the extraction attempt or shifts their weight to drive the knee through
Position Integration
Complete Pass from Flattened Half Guard serves as the critical bridge between the pressure-passing sequence and the side control attacking platform. Within the broader guard-passing system, this transition represents the culmination of a chain that typically begins with establishing top position in half guard, winning the underhook and crossface battle, collapsing the bottom player’s frames to achieve flattened half guard, and finally extracting the trapped leg to complete the pass. The transition connects directly to the Side Control submission tree including Americana, Kimura, arm triangle, knee on belly transitions, and mount advances. It also integrates with the knee slice passing system and smash passing methodology as the final completion step when those passes stall in the flattened half guard position.
