I can add that there was a big improvement in chess programs in the last year so
I can believe that gnuchess could beat the top programs of 1997
with time advantage of 5:1.

I read that gnuchess beated the top programs when it had
better hardware some years ago but software gets better and
I guess that today it is going to need
at least 1 hour per move against 3 minutes per move only to get 50%.

Maybe Bob hyatt can try to play a winboard tournament of gnu
against Crafty when Crafty is using hardware is
5 times slower(if it is impossible than telling crafty to
do nothing in part of it's search can emulate this situation).

Crafty is not the best program but I expect even Crafty
to get more than 50% when the time control is slow enough.
