(CNN) – There is much debate now over whether Russian President Vladimir Putin's military moves in Crimea are just a show of force, or whether he seeks to reclaim that part of southern Ukraine.
To Garry Kasparov, a former world chess champion from the Soviet era and now a pro-democracy activist, it is "quite obvious" that Russia is serious. "I don't think Crimea's the end of the story."
Kasparov, in an interview with CNN’s “The Lead with Jake Tapper,” said Putin “clearly has an appetite to – at least in his mind – to go after restoration of the great Russian empire. As much as he can grab, he would."
Kasparov, a council member of The Human Rights Foundation, left Russia last year.
He agrees with President Barack Obama’s assessment that the current standoff with Moscow is not "some Cold War chessboard."
"In chess we have rules, and clearly Putin doesn't care about rules," said Kasparov. "What he has been doing now in Ukraine – it violates international law, and international treaties Russia has signed before."
