30 Techniques. 4 Categories.

Submissions, sweeps, passes, and takedowns — the building blocks of every match. Each technique is mapped to its origin position and success patterns.

Submission

Rear Naked Choke

The king of submissions. Applied from back control — the highest-percentage finish in competition history.

Submission

Heel Hook

Rotational attack on the knee/ankle. The technique that changed modern no-gi grappling forever.

Sweep

Berimbolo

Inverted back take from De La Riva guard. The signature move of the Mendes brothers era.

Pass

Knee Slice

The most reliable guard pass at every level. Slice the knee through the guard to achieve side control.

Submission

Triangle Choke

Leg triangle around the neck from guard. One of the most versatile attacks in the BJJ arsenal.

Takedown

Double Leg

Attack both legs from standing. Wrestling's most fundamental technique, adapted for BJJ competition.

Pass

Body Lock Pass

Clinch the body and drive through guard. The dominant passing style of the modern pressure game.

Submission

Armbar

Hyperextend the elbow joint. Available from mount, guard, side control — the universal attack.
