What is the earliest recognition cue that a Sickle Sweep is being set up from De La Riva Guard?

The earliest cue is when the guard player begins shifting their hips to create a 45-degree angle from your centerline while establishing a deep collar grip behind your neck. This hip angle shift is the foundation of the entire sweep - without it, the sickle motion lacks the mechanical advantage needed to generate sufficient off-balancing force. Recognizing this angle change before the collar grip is fully established gives you maximum time to respond.

Why is stripping the collar grip more important than addressing the De La Riva hook when defending the Sickle Sweep?

The collar grip serves as the multiplying factor that makes the sweep finish. Without it, even a perfect sickle motion can be defended by posting your hands on the mat. The collar grip prevents posting, adds directional pull force to the sweep, and controls your posture. Stripping the hook alone still leaves you vulnerable to being swept if the collar grip pull breaks your posture forward, whereas stripping the collar grip gives you immediate posting ability regardless of the hook's position.

Your opponent has already loaded the sickle motion and you feel yourself beginning to fall - what is your emergency response?

Post your hand firmly on the mat on the side you are being swept toward and lower your center of gravity as much as possible. Accept that the sweep may partially succeed but focus on preventing the complete topple that gives them mount. From the posted hand position, immediately look to transition your defense into an offensive scramble - you can pull guard, shoot for a single leg from the kneeling position, or use the post to backstep and establish side control before they complete the transition to top.

How can you use the opponent's Sickle Sweep commitment as a passing opportunity?

When the guard player commits to the sickle motion, they necessarily extend both legs and shift their weight to one side, creating a momentary opening. If you can maintain your base through the initial off-balance, their extended legs and committed hips create an excellent opportunity for a backstep pass over the extended hook, a leg drag by grabbing their extending leg and driving it across your body, or a pressure pass by dropping your weight into their extended structure. Their commitment means they cannot quickly retract to a defensive guard position.

What base configuration provides the strongest defense against the diagonal sweeping angle of the Sickle Sweep?

A wide, staggered stance with your far leg positioned back and laterally to the side provides maximum resistance to the diagonal sweep. This creates a triangular base where the widest dimension is aligned against the sweep's primary force vector. Your hooked leg should have a slight bend with your weight distributed toward your far leg rather than centered or forward. This configuration forces the guard player to overcome a much wider base structure and gives you more time to recognize and react to the sweep attempt.

Sickle Sweep Defender | BJJ Defense Guide

Defending the Sickle Sweep requires the top player to recognize the attack early and respond with precise base adjustments before the sweeping motion generates full momentum. The Sickle Sweep is dangerous because it combines a powerful arc-shaped hook extension with upper body control, creating a rotational off-balance that is difficult to recover from once it begins. The defender’s primary advantage is that the sweep requires specific setup conditions - a deep De La Riva hook, a strong collar grip, and a diagonal hip angle - and disrupting any of these components significantly reduces the sweep’s effectiveness.

The defender’s strategic framework centers on denying the sweeping angle while maintaining strong posture and base. The most critical moment is when the guard player begins to shift their hips to create the 45-degree angle that powers the sickle motion. If the top player can flatten the bottom player’s hips or strip the collar grip before this angle is established, the sweep becomes nearly impossible to execute. Understanding the timing windows where the sweep is vulnerable allows the defender to shut down the attack proactively rather than reacting to a fully loaded sweep.

Advanced defenders learn to use the Sickle Sweep attempt as a passing opportunity. When the guard player commits to the sickle motion, they necessarily extend their legs and shift their weight, creating momentary openings for backstep passes, leg drag entries, and pressure passes that exploit the guard player’s committed body position. This counter-offensive mindset transforms defensive awareness into passing opportunities.

Opponent’s Starting Position: De La Riva Guard (Bottom)

How to Recognize This Attack

How do you know when someone is attempting Sickle Sweep?

Guard player shifts hips to approximately 45 degrees from your centerline, creating the diagonal sweeping angle required for the sickle motion
Strong collar grip is established deep behind your neck combined with sleeve control, indicating upper body control setup for the sweep
Guard player’s bottom foot repositions from distance management to pushing actively on your far hip, loading the push-pull mechanism
De La Riva hook tightens with increased toe flexion and the hooking leg begins to extend in a wide arc away from your body
Guard player elevates their hips off the mat while pulling down on your collar, indicating the sweep execution is beginning

Key Defensive Principles

What are the key principles for defending Sickle Sweep?

Maintain upright posture with hips back to resist the forward pull of the collar grip and prevent being loaded onto the hooked leg
Strip or neutralize the collar grip early, as this is the primary mechanism that prevents you from posting your hands to recover base
Keep your base wide by positioning your far leg back and to the side, denying the diagonal sweeping angle the attacker needs
Address the De La Riva hook actively by circling your hooked leg or driving your knee to the mat to reduce the hook’s leverage
Recognize the hip angle shift as the primary telegraph - when you see the guard player angle their hips to 45 degrees, the sweep is imminent
Use the opponent’s commitment to the sweep as a window to initiate your own guard pass before they can reset

Defensive Options

What can you do to defend against Sickle Sweep?

1. Step far leg back and widen base while stripping collar grip

When to use: Early prevention - when you recognize the hip angle shift and collar grip establishment before the sickle motion begins
Targets: De La Riva Guard
If successful: Neutralize the sweep entirely and maintain your passing position with improved base, allowing you to restart your pass attempt
Risk: Widening base too much can expose you to X-Guard or Single Leg X entries if the guard player reads your adjustment

2. Post hand firmly on the mat on the side you’re being swept toward while maintaining low center of gravity

When to use: Mid-sweep reaction - when the sickle motion has already begun and you cannot widen base in time to prevent the off-balance
Targets: De La Riva Guard
If successful: Stop the sweep mid-execution and create an opportunity to reset your base or transition to a passing sequence
Risk: Posted arm becomes vulnerable to omoplata attack or the opponent may use it to climb to your back

3. Drop weight forward and drive hips into the guard player to flatten their angle and collapse the sweeping structure

When to use: When you feel the collar grip pulling you forward and the hook beginning to extend - use their own pull to drive into them
Targets: Open Guard
If successful: Flatten the guard player’s hips, killing the 45-degree angle and neutralizing both the hook leverage and the sickle motion
Risk: Committing weight forward exposes you to Kiss of the Dragon inversions and Reverse De La Riva back takes

4. Backstep over the De La Riva hook to extract your leg and immediately initiate a backstep pass

When to use: When you read the sweep setup early and want to counter-attack rather than simply defend, using their commitment against them
Targets: De La Riva Guard
If successful: Extract your leg from the hook entirely and land in a passing position behind the guard player’s legs
Risk: Mistimed backstep can put you in a worse position with your back partially turned to an active guard player

Best-Case Outcomes for Defender

What is the best outcome when defending Sickle Sweep?

→ De La Riva Guard

Strip the collar grip early and widen your base by stepping your far leg back before the sickle motion generates momentum. Once the immediate sweep threat is neutralized, work to address the DLR hook through backstep or pressure to begin your pass. This resets the position to a neutral guard engagement where you retain initiative.

→ Open Guard

When the sweep attempt fails completely - either through successful base widening, collar grip strip, or the guard player overcommitting to the sweep and losing hook contact - immediately capitalize by initiating a guard pass before they can re-establish their DLR control structure. The moment of sweep failure creates a brief window where the guard player’s legs are extended and grips are compromised.

Common Defensive Mistakes

What mistakes should you avoid when defending Sickle Sweep?

1. Leaning forward with weight over the hooked leg when feeling the collar grip pull

Consequence: Loading weight onto the hooked leg is exactly what powers the sickle sweep - you are feeding directly into the sweep’s mechanics and making it higher percentage
Correction: Sit your hips back and maintain upright posture when you feel the collar grip pulling. Your weight should shift to your far leg and your hips should move backward, not forward over the hook

2. Keeping feet close together in a narrow stance while in opponent’s De La Riva Guard

Consequence: A narrow base provides minimal resistance to the diagonal sweeping motion and makes it easy for the opponent to compromise your structure from any angle
Correction: Maintain a wide, staggered stance with your far leg positioned back and to the side. This creates a triangular base that resists the diagonal sweep direction and gives you more time to react

3. Ignoring the collar grip and focusing only on the De La Riva hook

Consequence: Even if you address the hook, the collar grip prevents posting and creates the pull that completes the sweep. The upper body control is what makes the sweep finish
Correction: Prioritize stripping or neutralizing the collar grip first, as it is the component that prevents your primary defense (posting hands) and adds sweeping force to the leg mechanics

4. Attempting to step directly backward to escape the hook rather than circling or backstepping

Consequence: Stepping straight back pulls you through the exact arc of the sickle motion and can actually accelerate the sweep if timed with the opponent’s extension
Correction: Circle laterally away from the hooking leg or backstep over the hook to extract your leg. Lateral and rotational movement defeats the sweep’s linear force vector more effectively than linear retreat

5. Freezing in place and waiting for the sweep instead of proactively disrupting the setup

Consequence: Giving the guard player time to establish all setup components (angle, grips, hook tension) allows them to load a fully powered sweep that becomes nearly impossible to defend reactively
Correction: Be proactive - the moment you recognize DLR engagement, begin grip fighting and base adjustments. Deny the setup conditions rather than trying to defend the fully loaded sweep

Training Progressions

How do you train defense against Sickle Sweep?

Week 1-2: Recognition and Base Awareness - Identifying sweep setup cues and maintaining proper base Partner establishes De La Riva guard and slowly goes through the Sickle Sweep setup without completing it. Defender practices recognizing the hip angle shift, collar grip establishment, and hook tension changes. Focus on maintaining wide base and upright posture. Partner signals each setup phase so defender learns to identify them in real time.

Week 3-4: Grips and Prevention - Stripping collar grip and denying the sweeping angle Partner attempts to establish full Sickle Sweep setup with moderate resistance. Defender practices collar grip stripping techniques, base widening responses, and hook neutralization through backstep or pressure. Work on timing the grip strip before the sweep loads. Switch roles each round to understand both perspectives.

Week 5-8: Emergency Defense and Recovery - Defending mid-sweep and recovering position when caught Partner executes the Sickle Sweep at moderate speed and power. Defender practices posting, base recovery, and emergency responses when the sweep is already in motion. Develop comfort with the feeling of being off-balanced and practice converting defensive posts into scramble opportunities. Include drilling the transition from defensive post to guard pass.

Week 9+: Counter-Offensive Integration - Using sweep defense as passing opportunity Full resistance drilling where partner attempts Sickle Sweep and defender works to not only prevent the sweep but convert the defense into a guard pass. Practice backstep passes over the committed hook, leg drags from the extended leg, and pressure passes through the guard player’s extended structure. Develop the mindset of treating every sweep attempt as a passing opportunity.
