The guillotine punishes one of the most common mistakes in grappling: a exposed neck on a failed takedown. Here is how to finish it correctly.

The guillotine is a front choke. You wrap your opponent's neck as they shoot in for a takedown or leave their head exposed. It's one of the most common submissions in both BJJ and MMA, since it punishes a mistake almost every grappler makes at some point.

There are two versions. A high, tight grip across the carotid arteries creates a blood choke. It works fast and needs less strength. A lower grip on the windpipe creates an air choke. It's slower and more uncomfortable for both people. Aim for the blood choke whenever you can.
Marcelo Garcia popularized the arm-in guillotine. You trap one of your opponent's arms inside the choke along with their neck. This removes one of their main defensive tools and makes the choke far harder to escape.
The instant your neck gets caught, turn your head toward your opponent's choking arm and drive forward. Posting your hands on the mat and stepping around the choke removes most of the danger before it fully locks in — but keep moving once you do. A defense that stops at the posted-head stage can walk straight into a Von Flue choke instead.

The instant your neck gets caught, turn your head toward the choking arm and drive forward. Post your hands on the mat and step around the choke before it fully tightens.
Yes. It is a blood choke rather than a joint lock, so it is legal at every belt level under IBJJF rules.
