Frequently Asked Questions
What's the first choke to look for when my opponent is in turtle position?
According to Eli Knight, start by establishing a chin strap with your arm across the trachea while hugging the jawline, then drive your chest toward the base of their shoulder so their head goes into your diaphragm. Cup your second hand and drive forward while cutting back—this creates a sharp ten-finger guillotine.
How do I transition to an arm triangle if they defend the initial choke?
Eli Knight explains that if they block with their arm, cup the back of their bicep, pull back to open space, then shoot your arm through under their armpit with your back hand against their lat and shoulder. Once you roll to mount position, squeeze and bring your other leg over for an arm triangle or anaconda choke.
What's the difference between entering by the neck versus by the armpit for the arm triangle?
Eli Knight teaches two setups: entering by the neck and out by the armpit leads to one choke variation, while entering by the armpit and out by the neck allows you to cup both hands together, use an S-grip, and crank under their armpit to flip them before shooting your arm in deep with your bicep across their neck.
