Brabo Choke (D'arce choke) from Top Half Guard (No Gi)

The D'arce / Brabo choke is a BJJ move that is gaining popularity.  Paulo Thiago recently defeated Mike Swick at UFC 109 using this choke. The below is re-posted from Stephan Kesting.

	In this technique Marcio finds himself in Marco’s half guard, but without the gi.
	Marcio wraps his right arm around his opponent’s left arm and cups his head with the other hand.
	Marcio inserts his right arm even deeper, cups his opponent’s head with both hands and pulls it towards himself
	He now circles his left arm free…
	…and locks his arms together, trapping his opponent’s head and one arm
	Marcio applies the choke by driving forward and lifting his right shoulder up.
