Let me quote the email posted 21/11/2003. it is very clear that the hardware setup chosen by Peter Berger is what you referred to as: "If it loses I should obviously retire from computer chess due to gross incompetence. It will fortell of things to come with 100X time odds, although I am sure some will expect to lose even it it wins with 10x."
