The Guillotine Choke is a submission technique commonly used in grappling sports like Brazilian Jiu-Jitsu and MMA. It involves wrapping the opponent's neck with the attacker's arm while securing their body with the other arm or legs. This creates a choking effect that can force the opponent to tap out or lose consciousness if applied correctly. To execute the Guillotine Choke, the attacker typically needs to be in a standing or kneeling position while the opponent is attempting to shoot for a takedown. Proper positioning and grip are crucial for effectiveness, as the choke relies on leverage and pressure to restrict airflow and blood flow to the brain.
