The DJ vs DF match for the right to play against Kramnik would attest to the wisdom of doing that! >Unless that is what the machine is programmed for, before the match. >Not, discrimination between game and game. That's the human prerogative alone. >Possibly, to intervene that the computer play a different opening is not as bad >as if this game was programmed to aim for a draw. >S.Taylor "Programmed" would be putting it strongly. Programs have a "contempt factor", which is an adjustable parameter. What the match rules allow with respect to this is anyone's guess. For all we know, DJ's contempt factor is set to *always* go for the draw against Kasparov. Please remember that I'm just speculating. We don't know what the cause of the sac was, or what DJ thought of it. Andrew
