RDLR to Crab Ride Attacker

Executing RDLR to Crab Ride requires precise coordination of hip elevation, rotational mechanics, and immediate hook insertion upon arrival at the target position. The attacker uses the Reverse De La Riva hook as a fulcrum to generate rotational momentum needed to thread underneath the opponent, arriving perpendicular to their spine in the crab ride position. Unlike direct berimbolo entries that commit to full back rotation, this transition provides a controlled stopping point at crab ride where the attacker can consolidate control before advancing to back takes or submissions. Success depends on reading the opponent’s weight distribution to identify the optimal inversion window, timing the entry precisely when their base is compromised, and transitioning smoothly from guard player to dominant crab ride controller without losing connection during the inversion.

Key Attacking Principles

Hip elevation creates the vertical space needed to thread underneath the opponent—flat hips make inversion impossible
The RDLR hook serves as the primary fulcrum for rotation, and its depth determines the arc and direction of the inversion
Ankle grip controls both the direction of the inversion and prevents the opponent from disengaging during the transition
Speed of hook insertion upon arrival determines whether the opponent can react and escape before crab ride consolidates
Upper body control must follow hook insertion immediately—the crab ride without upper body grips is unstable
Weight commitment through the chest onto the opponent’s shoulder blade completes the positional transition from guard to ride

Prerequisites

Deep RDLR hook threaded behind opponent’s far knee with instep engaged around their thigh, creating the fulcrum for inversion
Near-side hand firmly controlling opponent’s far ankle, providing the steering mechanism for directional inversion
Hips elevated off the mat with core engaged, creating approximately 45-degree angle with the ground for dynamic mobility
Far leg framing on opponent’s near hip to prevent forward drive and maintain space for the inversion pathway
Opponent’s weight loaded onto the hook-side leg through active pull on ankle grip, compromising their ability to sprawl

Execution Steps

Establish RDLR Hook and Ankle Grip: From Reverse De La Riva Guard bottom, ensure your inverted hook is threaded deeply behind the opponent’s far knee with instep engaged around their thigh. Your near-side hand must firmly control their far ankle—this grip serves as both the steering mechanism for the inversion and the anchor preventing their escape during the transition.
Elevate Hips and Create Angle: Engage your core to lift your hips off the mat, establishing approximately a 45-degree angle with shoulders elevated. Your far leg frames on the opponent’s near hip, preventing them from driving forward to flatten your guard structure and maintaining the vertical space necessary for inversion underneath them.
Load Opponent’s Weight onto Hook Side: Pull their far ankle across your centerline while simultaneously increasing hook pressure through your inverted leg to disrupt their base. You need their weight committing onto the hook-side leg so they cannot sprawl or backstep effectively when you initiate the inversion underneath them.
Initiate Inversion: Tuck your chin firmly to your chest and rotate your shoulders toward the mat on the hook side, beginning to thread your body underneath the opponent. The RDLR hook serves as the primary fulcrum for this rotation—your entire body pivots around this contact point as you invert through the available space.
Thread Underneath Opponent: Continue the rotation underneath your opponent while maintaining connection through your hook-side leg as you pass through. Your far leg releases the hip frame and begins transitioning to search for the crab ride hook insertion point on the opponent’s near-side hip crease.
Insert Crab Ride Hook: As you emerge perpendicular to the opponent’s spine, immediately insert your near leg as the crab ride hook under their hip with your foot positioned inside their thigh. This hook must be established before the opponent can react to your positional change and initiate their escape or guard recovery protocols.
Establish Upper Body Control: Secure control of the opponent’s far arm, shoulder, or collar while driving your chest firmly against their ribs and shoulder blade. Your body should now be oriented perpendicular to their spine in the characteristic crab ride configuration, with weight committed through your chest rather than sitting back.
Consolidate Crab Ride Position: Settle your weight into the crab ride by pressing your chest into their shoulder blade and engaging the hook actively to prevent any forward movement or guard recovery. Establish your free leg as a posting base for stability, completing the transition from RDLR guard player to dominant crab ride controller.

Opponent Counters

Sprawl and drive hips to the mat to flatten the RDLR player and eliminate inversion space (Effectiveness: High) - Your Response: Abort the inversion early and return to RDLR guard retention. Reattempt when the opponent relaxes their sprawl pressure, or redirect into a waiter sweep that capitalizes on their forward weight commitment. → Leads to Reverse De La Riva Guard
Strip the ankle grip using wrist control or two-on-one break before inversion begins (Effectiveness: High) - Your Response: Immediately transition to alternative RDLR attacks like Kiss of the Dragon or X-Guard entry before losing guard structure entirely. Re-establish the ankle grip only if the opponent gives you the opening. → Leads to Reverse De La Riva Guard
Backstep away from the RDLR hook to disengage and create distance (Effectiveness: Medium) - Your Response: Follow the backstep by converting to Single Leg X-Guard or X-Guard entry using their retreating momentum. Their backstep often opens the space needed for these guard transitions. → Leads to Open Guard
Crossface to block shoulder rotation and prevent the inversion from initiating (Effectiveness: High) - Your Response: Use the crossface pressure to load their weight forward, converting their defensive pressure into a waiter sweep opportunity. Their forward commitment while crossfacing feeds directly into your sweeping mechanics. → Leads to Reverse De La Riva Guard

Common Attacking Mistakes

1. Attempting the inversion without first securing a strong ankle grip

Consequence: The opponent can freely backstep, disengage, or sprawl during the inversion since there is no steering mechanism controlling their base. The inversion stalls midway with no pathway to complete the transition.
Correction: Always establish and verify your ankle grip before initiating hip elevation and shoulder rotation. The ankle grip is non-negotiable—it controls the opponent’s base and directs the inversion arc.

2. Keeping hips flat on the mat during the inversion attempt

Consequence: Insufficient vertical space to thread underneath the opponent, resulting in a stalled inversion where you end up pinned beneath their weight without achieving the perpendicular angle needed for crab ride.
Correction: Actively elevate hips through core engagement before initiating the shoulder rotation. Your hip height determines the available space for the inversion—higher hips create a larger arc for threading through.

3. Releasing far leg hip control before the inversion is committed

Consequence: Telegraphs the inversion attempt and allows the opponent to drive forward with pressure, flattening your guard structure and eliminating the inversion pathway before it develops.
Correction: Maintain far leg framing on the opponent’s near hip until your shoulders begin rotating. The far leg releases only when your body is already committed to the inversion and your hook-side leg has taken over as the primary control point.

4. Failing to insert the crab ride hook immediately upon arriving perpendicular to the opponent

Consequence: The opponent recognizes the positional change and either sits through to recover guard, turns into you to prevent hook insertion, or stands up before you can consolidate the crab ride control.
Correction: Hook insertion must be instantaneous and automatic upon emergence from the inversion. Drill the hook insertion timing as the critical checkpoint—arrival without immediate hook is a failed transition.

5. Over-rotating past the crab ride position and ending up behind the opponent without control

Consequence: You end up in an uncontrolled scramble behind the opponent where neither back control nor crab ride is established, giving the opponent time to turtle defensively or escape entirely.
Correction: Arrest the inversion rotation at the perpendicular angle to the opponent’s spine. Practice stopping the inversion precisely at crab ride rather than continuing through. Your chest against their shoulder blade is the brake point.

6. Neglecting upper body control after inserting the crab ride hook

Consequence: The hook alone is insufficient to maintain crab ride—without upper body control, the opponent can turn into you, sit through, or create the space to strip the single hook and escape to guard.
Correction: Upper body control must follow hook insertion within one to two seconds. Immediately establish control on the opponent’s far arm, shoulder, or collar while driving chest pressure into their ribs. Hook plus upper body equals consolidated crab ride.

Training Progressions

Phase 1: Solo Inversion Mechanics - Developing the hip elevation, shoulder rotation, and body threading movement pattern Practice the inversion movement solo on the mat, focusing on tucking the chin, rotating shoulders, and threading through an imaginary space. Build the muscle memory for the rotational arc and practice arresting the motion at the perpendicular crab ride angle. Perform 20 repetitions each side per session.

Phase 2: Cooperative Partner Drilling - Executing the full transition against a stationary, cooperative partner Partner assumes standing or combat base position while you establish RDLR and execute the full inversion to crab ride sequence. Partner remains passive, allowing you to develop timing for ankle grip engagement, inversion initiation, hook insertion, and upper body control establishment. Perform 10 repetitions each side.

Phase 3: Progressive Resistance Drilling - Maintaining technique quality against increasing defensive pressure Partner provides graduated resistance starting at 30% and increasing to 75% over multiple rounds. Partner uses realistic defensive reactions—sprawling, grip fighting, backstepping—while you adjust timing and execution to overcome each defensive layer. Focus on recognizing when to commit versus abort the inversion attempt.

Phase 4: Live Positional Sparring - Applying the transition in realistic conditions with full resistance Positional sparring starting from RDLR guard with the attacker working to achieve crab ride and the defender working to pass or disengage. Full resistance from both players with resets when either objective is achieved. Track success rate across rounds and identify common failure points for targeted improvement.

Test Your Knowledge

Q1: What is the optimal moment to initiate the inversion for RDLR to Crab Ride? A: The optimal inversion window opens when the opponent’s weight shifts forward onto the hook-side leg, typically during a passing attempt or when they reach to address your ankle grip. Their forward weight commitment prevents them from sprawling effectively when you initiate the rotation. You can also create this window artificially by threatening a waiter sweep, which forces forward weight adjustment to defend, then immediately switching to the inversion. The key indicator is feeling their weight load through your hook—when the hook feels heavy, their base is compromised.

Q2: What grip and hook conditions must be established before attempting the inversion? A: Three non-negotiable conditions must be present: deep RDLR hook threaded behind the opponent’s far knee with instep engagement around their thigh, a secure near-side hand grip on their far ankle controlling the direction and speed of their potential movement, and hips elevated off the mat with core engaged to create the vertical space needed for threading through. The far leg should also be framing against their near hip. Attempting the inversion without any one of these elements dramatically reduces success probability and increases counter risk.

Q3: How does hip elevation affect the success of the inversion underneath your opponent? A: Hip elevation directly determines the available space for threading your body underneath the opponent during the inversion. Higher hips create a larger arc of movement, making it easier to rotate your shoulders through and emerge on the far side. Flat hips eliminate this space entirely, causing the inversion to stall with your body pinned beneath the opponent’s weight. The hip height also affects the rotational momentum—elevated hips allow your core to generate the rotational force needed to complete the movement smoothly rather than grinding through resistance.

Q4: What is the most common reason the RDLR to Crab Ride fails during the inversion phase? A: The most common failure point is initiating the inversion without sufficient opponent weight loaded onto the hook side. When the opponent’s weight remains centered or shifted away from the hook, they can sprawl, backstep, or simply drive forward to flatten the inverting player before the rotation completes. The ankle grip pull must actively displace their weight before the shoulder rotation begins. A secondary common failure is releasing far leg hip control prematurely, which telegraphs the inversion and allows preemptive defensive positioning.

Q5: Which grip is most critical for controlling the direction of the inversion, and why? A: The near-side hand grip on the opponent’s far ankle is the most critical grip. This grip serves dual purposes: it prevents the opponent from stepping away or disengaging during the inversion, and it controls the direction of the rotational arc by pulling their base in the direction you want to invert toward. Without this grip, the opponent’s leg is free to move, eliminating the anchor point that makes the inversion path predictable and controlled. The ankle grip essentially converts an uncontrolled rotation into a steered pathway to crab ride.

Q6: In which direction should you apply rotational force during the inversion to arrive at crab ride? A: The rotational force should be directed toward the hook side—specifically, your shoulders rotate toward the mat on the same side as your RDLR hook. This creates a rotation that threads your body underneath the opponent from the hook side through to the far side, arriving perpendicular to their spine. The hook serves as the axis of rotation. Rotating in the opposite direction (away from the hook) would pull you away from the opponent rather than threading underneath, resulting in guard disengagement rather than positional advancement.

Q7: Your opponent recognizes the inversion and begins sprawling their hips to the mat—how do you adjust? A: If the sprawl is early and you haven’t committed to the inversion, abort immediately and return to RDLR guard retention. From there, redirect their forward weight commitment into a waiter sweep—their sprawl pressure actually feeds into sweep mechanics since they’ve loaded their weight forward. If you’ve already partially committed to the inversion when the sprawl hits, your best option is to maintain your hook and ankle grip while recovering your hips to RDLR position, then reattempt once they relax the sprawl. Never force a stalled inversion against sprawl pressure.

Q8: If the opponent successfully defends the crab ride entry by turning toward you during your arrival, what follow-up attacks become available? A: When the opponent turns toward you during crab ride establishment, they create back exposure on the opposite side. This opens direct back take opportunities—follow their turning momentum and transition to establishing back hooks rather than fighting to consolidate crab ride against the turn. If they turn aggressively, a guillotine or darce choke may become available as their neck enters your control space. The key principle is to capitalize on their defensive momentum rather than resist it, converting their escape into your next attack.

Safety Considerations

RDLR to Crab Ride involves inversion mechanics that place significant stress on the cervical spine during the threading motion underneath the opponent. Never force the inversion if your neck becomes compressed or your rotation path is blocked by the opponent’s weight. Tap immediately if you feel cervical loading during a failed inversion attempt. Training partners should avoid driving full bodyweight onto an inverting player’s head or neck. Build cervical stability and inversion comfort progressively through solo drilling before attempting the technique under resistance. Practitioners with existing neck injuries should consult a medical professional before training inversion-based techniques.
