The Estima lock is a sneaky foot lock submission named after Braulio Estima, a multiple world and ADCC champion who used it to defeat Marcelo Garcia at ADCC 2009. What makes it unique: it attacks the foot of someone who is passing your guard β turning their offensive action into a submission trap.

How It Works
1
Opportunity β The Estima lock appears when your opponent steps their foot forward into your guard space while passing β typically in a toreando or leg-drag pass.
2
Trap the foot β Catch their stepping foot by hooking your arm over their shin, trapping the foot against your body. Their toes should point upward.
3
Finish β Extend your hips forward while rotating the trapped foot β creates a rotational toe/foot lock. Tap comes fast.
When to Hunt It
1
Toreando pass β Classic entry β as they grip your pants to toreando, their foot is vulnerable as they step.
2
Knee slice β As they push your knee to slice, step their leg into the lock position.
3
Any forward step β Any time they step a foot forward between your legs, the Estima lock is available.
Legal Status
1
