### Guillotine Defense in Brazilian Jiu-Jitsu
Guillotine choke attempts are common in various positions in BJJ, especially from the standing, turtle, or guard configurations. Below are detailed steps to escape these chokes effectively.
#### Position
- **Standing**
- **Turtle**
- **Closed Guard**
### Steps for Defense
#### **Standing Guillotine Defense**
1. **Posture**: As soon as your opponent wraps your neck, immediately lower your stance and straighten your back. This makes it harder for your opponent to control you.
2. **Grip Defense**: Use your outside hand to grip the opponent’s wrist that is choking you, relieving pressure off your neck.
3. **Head Position**: Tuck your chin and drive your head into your opponent's ribs.
4. **Position Change**: Step one foot back and circle your non-choked shoulder towards the opposite hip to give more space and lessen pressure.
5. **Hip Drive**: Push your hips forward and drive your opponent backward, utilizing the straightening of your posture to break their leverage.
6. **Escape and Control**: Once freed, gain top control by advancing to an advantageous position, like side control.
#### **Turtle Position Guillotine Defense**
1. **Control the Opponent's Wrist**: Immediately attack the opponent's choking arm by controlling their wrist with your near-side arm.
2. **Head Position**: Lower your head to the ground to prevent upward pressure against your throat.
3. **Shoulder Pressure**: With your far hand, grab the opponent’s far shoulder, applying shoulder pressure.
4. **Roll**: Execute a forward roll, elevating your hips to create space. Roll over the choking shoulder while maintaining wrist control.
5. **Guard Recovery or Top Control**: After the roll, either recompose your guard or move to a favorable top position, controlling your opponent until their grip loosens.
#### **Closed Guard Guillotine Defense**
1. **Posture Up**: While keeping a straight back, bring your choking arm's hand across your body, gripping your opponent's wrist.
2. **Post**: Using your free hand, post on your opponent’s hip or chest to prevent them from pulling you down further.
3. **Elbow Drive**: Slide your elbow over your opponent's shoulder on the side opposite of the wrist you're controlling.
4. **Pressure and Turn Angle**: Apply downward pressure while turning your body slightly to gain leverage.
5. **Head Push**: Use your free hand to push your opponent’s head backward.
6. **Pass Guard or Stay in Half Guard**: After releasing the choke, transition towards a guard pass or secure a dominant position.
