glad you guys liked the clip. It's my favorite move because they follow proper BJJ laws if they're stuck in sidemount, halfguard, etc. and still get caught in the choke! Here's a clip of the exact Darce setup that Drysdale used to beat Marcelo Garcia in ADCC 2007 to win the Absolute Division.

Skip to 9:02 and you will see Drysdale use the above clips' setup to beat Marcelo for the ADCC championship with the Darce/Brabo choke!
Darce/Brabo (the forum member) really gave me a lot of good tips on it. Hr has some good info on the choke as well. Here:
To quote him:
"Surprised it took me this long to notice this thread. I find actually that the way Ryan describes it, cranks, more than chokes. In order to REALLY get a solid choke from the Darce (mind you, this is all of my non-adcc experience, lol), you have to understand 3 key pressures, and where they are coming from:
This example is assuming you have a right handed Darce
1st Pressure - Your forearm into their right Carotid Artery
2nd Pressure - Your chest driving their shoulder into their left Carotid Artery
3rd Pressure - You pulling their head into their chest with your left elbow (RNC Grip)
I found by doing it that way, the right should naturally raises on its own.
Finishing the Darce
As for finishing it, im not too found of sprawling my legs out, because you get some of those wormy, rubbery, lower back flexibility types, they will always somehow manage to re-guard, and start hitting Darce counters. The two ways that I've found that work really well to prevent that are by either:
A) Keeping your right foot (instep) flat to the mat, and using your knee to block his hips
B) Completely stepping your right leg over his torso, then applying the 3 pressures (this sucks balls, and can be a horrible crank if they try to resist)
