oh yeah ofcourse I forgot to put, Pentium III 1Ghz.

Even though I am not going to try to say that my test is the best. but probably
is not worthless either.

1) POnder off is a default setting  under CB interface. Since both programs are
not pondering, I dont see a problem

2)Both program used same opening book from a well-known set of pgn file. If
there is anything wrong with the opening book, both program will suffer. As the
opening is reversed in every game. IMO the strength of the program doesnt
include opening book, opening book is a way to increase the strenght of a
program.



It is a well-known fact in this forum, that you can never be perfect in a
eng-eng match. No matter how many games you play or whatever precautions you
take.

Even though the games were just fun, i was just trying to get some meaning out
of it.
