That gives me an idea.
 
 
Theory:  the "and I will name him George" strategy, wherein the Alvarezsaur 
grips the prey or prey-part to his chest and proceedes to hug the stuffing out 
of it - such as until the prey is ripped open.
(a PG-rated example can be found here: http://youtu.be/2JlVqfC8-UI)
 
Problems with the theory:  I think the best body part to use this on, would be 
the stomach and intestine (right? wrong?), which would be grabbed ahead of time 
by larger carnivores.
 
possible solution:  Alvarezsaurs used their long necks to dart in, grab the 
part, and run like the dickens far far away before hugging it?...or they 
focused their efforts on carcasses which were slightly mummified?
