Yeah, the game history has to be considered an important issue.  Most people &
programs don't consider the utterly ridiculous moves that _could_ happen, until
somebody who doesn't have a clue about the game plays them.  Things like 1.
P-KR4, why would you do that?  But if you don't know anything about Chess, that
seems like it makes sense.

So is everyone counting the utterly ridiculous?
