I mostly hit it from a mount or mounted monoplata type of situation where they sit up as I dismount, or reach down to try to hip escape out from mount. That and them turning in and fighting to their knees to escape the north south choke. I mostly try to sweep from the bottom, so I may snap on it from butterfly, but that's pretty much the only submission I attack from the bottom. Sometimes i hit it while I'm getting leg drag passed and hip out and wrap up the head as they're passing like Jeff Glover did to Robson Moura at ADCC '11. I used to hit it from turtle a lot, but I mostly attack seatbelts to the back, and darces/marces from there.

I completely agree. The darce and Marcelotine seem to be the chokes that are the easiest to chase through anywhere. Both can be finished from top half, side control, bottom half, bottom side control, the mount, closed guard, standing, the list goes on. A great drill to do is one that Ryan Hall shows on the arm triangles dvd set. He shows it with the darce, but you can easily do it with the guillotine too. You just loosely hold the choke, close your eyes if you like, and your partner will slowly start going flat back, fighting to their knees, front rolling, sitting out, whatever. Your job is to just follow them around and roll, slide, step over, pull guard, shrimp, whatever it takes to keep the choking position.
