Yes indeed! I surrender!! There seems no limit on the number 
of forced passes by the defender!

How about an alternative rule to reduce passes... can I say
"the defender never *has* to pass whenever there are any
legal moves the defender can make which aren't putting any 
of the *original* defending armies in self atari"?
