Guillotine choke

From CageWiki

A favorite for jiu-jitsu fighters taking on wrestlers with limited MMA experience as the guillotine choke punishes those who might try a takedown with their head down.

In short, a guillotine choke often happens after a sprawl that ends with an opponent's head in the performer's armpit. The performer then reaches around the opponent's chin without going around their arm and grasps the hand of the first arm with the second. From there they lift up, cutting off their opponent's air.

This move can be applied from a standing position (see Mirko "Cro Cop" Filipovic versus Kevin Randleman II). However, oftentimes performers choose to fall back into their guard for leverage.
