Introduction to the Chin-Down Problem
The rear naked choke is fundamental to Brazilian Jiu-Jitsu, but becomes significantly more difficult when an opponent buries their chin to their chest. This defensive position, especially pronounced in larger opponents, creates a barrier that prevents proper hand placement. The following five techniques address this common defensive scenario.
Setup Considerations: Gi vs. No-Gi
Training no-gi simplifies instruction and execution since the gi fabric adds friction and effectively increases the opponent's perceived shoulder and chest mass. However, the underlying principles demonstrated apply equally to gi training. The instructor will demonstrate from the knees for clarity while noting that proper positioning requires established rear mount hooks.
Method 1: Phoenix Eye Fist Entry
Derived from kung fu, the Phoenix Eye Fist—formed by extending a single knuckle forward—functions as a tapered wedge to penetrate the space beneath a tucked chin. Rather than a pressure point strike, this technique traces the jawline with a twisting motion to gradually elevate the chin. Once the hand achieves position under the jaw, the attacker can transition directly into the rear naked choke.
Method 2: Caterpillar Hand Progression
Using the fingertips, the attacker works underneath the opponent's chin tip with a sequential peeking and shooting motion—similar to a caterpillar advancing. Each repetition incrementally lifts the chin while advancing hand position deeper. Once the attacking hand reaches the far trapezius, establishing control over the far shoulder allows smooth choke insertion.
Method 3: Transition-Based Entry
By attacking with multiple simultaneous threats—such as overhook and underhook positioning—the defender's attention becomes divided. As the attacker executes rear mount entry with hook placement, they simultaneously sink the choke before the opponent can re-establish chin defense. This timing exploits the natural lag in defensive transition.
Method 4: Forehead Lever Manipulation
The attacker positions their arm across the opponent's face and pulls on the highest point of the forehead—maximizing mechanical leverage. This extended lever exceeds the strength capacity of the sternocleidomastoid muscle, forcing the head backward regardless of chin position. This method proves particularly effective when the opponent is face-down in rear mount.
Method 5: Direct Jaw Application—Advanced Technique
Applied directly over the opponent's jaw and chin, sustained pressure eventually forces the jaw to slightly dislocate, allowing the choke to engage the throat. This method requires significant grip strength and should only be used with experienced training partners in specific preparation contexts—never with beginners or smaller, less experienced opponents. Proper etiquette demands mutual consent before employing this advanced variation.
