In June 1999, I played Karpov in León, Spain, in an advanced game in which each player is teamed with a computer. It was intended to show how a human player and a computer working together could produce higher-quality games. I doubt we succeeded in doing that. As someone put it, ‘It was Anand with a computer against Karpov with a high-tech scoresheet,’ since the greater challenge for him seemed to be finding his way around using the computer.
