I am not sure I agree with that.  The 50 move rule was created some time ago to
make sure a game could not go on forever.  As time goes on and deeper analyses
take place we see that there is alot more oppurtunity to winning/drawing games
then what was previously thought of.  Is it fair if there exists a person who
can truly remember a 243 move sequence (granted not many) and gets into that
position is it fair to deny him the win?  I think not and therefore I think that
in the case where a person or computer can announce a position which is a
guaranteed mate the 50 move rule should be eliminated.  As I continue to study
the egtb's more and more mate positions which require >50 moves is increasing.
