Well, I think this is just a form of cheat. Tiger doesn't have a learning book
function working, Fritz is almost "brute force" in this field. You will see
almost the same games over and over. I really don't know why people do this, but
I really don't know why people cheats using computers without a (c) on servers
either, so... I really hope that the patch promised by Christophe will resolve
this part of problem, at last in part. In any case, however, I think it will be
always possible to play lines against a computer opponent to make your program
always win against it. As you see in fact the player you observed played almost
always against Tiger. You prepare some lines for a target and you begin to play
always that variations. Also if your program will learn it will never change his
play so much as to win that line, this is what I've seen till now in my
experiments, but maybe this is possible; if someone of the programmers would
illuminate me on this point I would be grateful.

For the hardware, I don't think the difference is so much as to make Tiger lose
extensively.

Naturally the same could be applied to Fritz (as a target) as well.

Sincerely,
Fabio.
