When [Vladimir] Putin, a former lieutenant-colonel in the KGB, became Russia's president on December 31, 1999 - eight years after the failed coup attempt against (then Soviet leader Mikhail) Gorbachev, and eight years after the people had torn down the statue of Felix Dzerzhinsky, the hated founder of the KGB, in Moscow - it was admittedly a shock.

It was an impressive achievement, of course, and a human achievement by the members of the IBM team, but Deep Blue was only intelligent the way your programmable alarm clock is intelligent. Not that losing to a $10 million alarm clock made me feel any better.

More and more people in my country recognise the dangers of having their governors appointed by Putin and having no influence in parliament because Parliament today is also following instructions from Kremlin and no longer represents its people.
