I certainly want to be involved in politics and help shape the transition. I am in contact with regime critics who had to leave for the West. One of them is Mikhail Khodorkovsky, the former businessman, who had to endure 10 years in a prison camp.

Revenge for a terror attack is ideal for Putin's model. His propaganda machine will be filled with scenes of crash victims if [Vladimir] Putin sees the need for a larger war to stoke his domestic support again as the Russian economy teeters.

We have to stop the propaganda, the shameful propaganda used by Kremlin to rehabilitate these old types.

I may play some exhibition games so I don't want to quit the game of chess completely. I just decided and it's a firm decision not to play competitive chess anymore.

I have some security that could protect me against provocations but of course there are more terrible actions that could not be stopped by any security.

If you wish to succeed, you must brave the risk of failure.

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by Putin and having no influence in parliament because Parliament today is also following instructions from Kremlin and no longer represents its people.
