"Brabo Choke" is very similar "D'Arce". Brabo is a North & South (69) Choke and "D'Arce" is more of a 90? Side Mount Choke. I'll post that Set-Up in a few.
"Whizzer" is an Over Hook pulling on the bicep from outside of the arm to create an openning.
Using that same direction, instead of pulling on the arm, spear your arm through with palm up so that your hand bites down and anchors on the back of your opponent's neck so that your hand is already in place when your other arm comes over to push opponent's head in with the back your elbow to lock and sinch in a full figure four for the choke.
