From the Foreword to Kasparov on Modern Chess II: Kasparov v Karpov.
“When work on this volume was approaching completion, I added to my life experience
by spending some time in jail. In late November 2007, just before the rigged parliamentary elections, I, like many other representatives of the opposition, clashed head-on with the police and the arbitrary judicial rule of Putin’s Russia. The five days spent in captivity became for me a fundamentally new reference point in my relations with people. From behind bars, everything, as in chess, is seen in black and white – many expressed their solidarity, but there were also those who did not pass the test of elementary decency.
Anatoly Karpov made an attempt to visit me in prison – the solidarity of champions
proved stronger than political and personal disagreements! He was not able to do this: the authorities, who did not allow any lawyers to see me, did not make an exception for Karpov. But in the new system of coordinates his goodwill gesture outweighed all the negative factors which had accumulated during our long years of confrontation.”
