Not clear to me.  Of course, I am not a professional chess programmer, so maybe
I wouldn't know.

But . . .

What is there to keep a chess programmer from writing code that forces the chess
engine to examine all such sacrifices?  Yes, I know there would be a few
technical difficulties.  But, what about the essence of this idea?  Is it so far
out from what is do-able?
