Rener Gracie and Rhalan Gracie provide a breakdown of UFC 126:
As they point out, Rocha displayed beautiful jiu-jitsu transitions against Ellenberger. They don’t mention that he seemed more interested in those beautiful transitions than in winning the MMA bout.
Anyway, they go into wonderful detail analyzing Rocha’s Kimura arm-bar attack from (under) the north-south turtle position. Rocha doesn’t sit through and sit up as much as in the variation I’ve used.
They also look at some of Jon “Bones” Jones’ amazing techniques, including his transition from D’Arce choke, to arm-in guillotine, to arm-out guillotine, to arm-out guillotine with his own forearm over the shoulder — a variation I just learned from Rodrigo Gracie — to push-grip guillotine — made famous by last year’s TUF competitor, Cody McKenzie.
