- BJJ
- Mount Attacks
- intermediate
- Mount / side control
- 3 steps

Trap one of the opponent’s arms across their own neck and squeeze with your shoulder to strangle. Also known as the Kata-gatame or the Head-and-arm choke. Here is the exact breakdown from the DARCE app: 3 steps, the details that make it work, and the mistakes to avoid.

## When to use it

Use the arm triangle from mount or side control when the opponent frames on your neck or chest with a straight arm. Push that arm across their neck and drop your head beside theirs. It works well against an opponent who pushes with one arm to escape.

## Step by step

1. 01

   ### Establish mount

   Control them and free one arm to push across.

2. 02

   ### Trap the arm across the neck

   Push their arm across their own throat and drop your head beside theirs, shoulder pressing the arm into the neck.

3. 03

   ### Lock & squeeze

   Lock your hands, slide off to the side and squeeze your shoulder and their own arm into both sides of the neck.

## Key details

- Their own shoulder chokes one side; your shoulder/arm the other.
- Drop off to the side to finish. Staying on top loosens it.
- Lock your hands and keep your head tight to theirs.

## Common mistakes

- Leaving a gap so they slip the head out.
- Squeezing without coming off to the side.
- Letting them pull the trapped arm back across.

## Common counters

Opponents pull the trapped arm back across, turn into you, or push your head away with their other hand. Staying on top loosens the choke. Lock your hands, slide off to the side and squeeze.

## How to drill it

From mount, trap the arm across the neck, drop your head beside theirs and slide off to finish, ten reps on each side. Then work three rounds of one minute from side control where your partner frames.
