De La Riva?

Where is De La Riva in the clip linked from the home page called "Defending the Guard Pass with Ricardo De La Riva"??  

 That is actually Ricardo "Rey" Diogo demonstrating a defense to a Margarida pass by forum member Andreh Anderson. The initial position is a deep hook de la Riva guard.

It is "Rey" Diogo demonstrating the Dela Riva guard on Andre. Dela Riva is probably in Brazil.

InvisiblePinkUni - That is a clip featuring at least one member of matbattle.
