Hi Sarah,
         I am not arguing on whether Ruffian is a crafty clone or not, and I
will not put my life onthe line for it, as I know little about the program.
What I am arguing about is that, it is possible to increase the playing strength
of a program in a short time.
And there is no need to think that every strong new program is a crafty clone.

However, there are some reasons that I think Ruffian is not a crafty clone.

1) It is a UCI/Winboard engine, crafty only supports Winboard.
2) It is perticipating in Leo's tournament, if anything looks suspecious about a
program, the first person I expect to find out is Leo. As he really goes in to
the details of a chess program before adding it to his tournament.
3) Beside Leo, several other testers, including Frank, is testing this program,
   One of this tester includes a programmer, Benny (sorry forgot full name).
4) It's results indicate that it is atleast 100-150 elo better than Crafty/Yace.
