I think that computer-human games are important in the developement of future chessprograms, and i enjoy the scrappy v humans games i dont think that there is anything wrong with having two accounts where one plays humans only as long as it serves a purpose, i am about to sign up for a 2 year membership for the sole purpose of having a program playing humans only, so we can get more insight as to what makes a program stronger against humans, we have plenty info on what makes a program stronger against another prog.
