rare naked giulotine

I remember seeing it on mts im hitting it mainly sprawl control / turtle. When i get my arm all the way through allowing me to rare naked my hands i struggle to get deep under the neck as they r dipping there chin so it turns into like a weird neck crank but the more i touque it the looser the whole technique gets espesicaly when they fall back to there back to try and deffend. Any advice

Rolling to their back is a common defense. Are you setting it up like you're doing a darce with no arm in? Cause I can't picture how its turning into a neck crank that way.

brent fix your pic, its fucking with me. lol
