Alexei Navalny, the opposition politician who has led anti-corruption protests, had a blog about a credit line to a company owned by Vladimir Putin's son-in-law, $1.75 billion from Russian state funds; this is one transaction. Putin controls more money directly and indirectly than any individual in human history.

One does not succeed by sticking to convention. When your opponent can easily anticipate every move you make, your strategy deteriorates and becomes commoditized.

The West can't come up with anything to deal with Moscow, except appeasement.

The Soviet Union tried to sell a set of ideas, very left wing, and focus on so-called peace. Vladimir Putin doesn't care who helps him to push his agenda. He is equally comfortable with the politics of Nigel Farage and Corbyn in Britain, Le Pen and Jean-Luc Mélenchon in France. Whether far left or nationalist, he doesn't care, as long as they support chaos and destruction and the undermining of existing institutions.

A very strong player can manage and can just know how to manage a thousand positions. I get it; it's a very arbitrary number. So then you have the world champion who could do more. But, again, any increase in numbers creates, sort of, a new level of playing. And then you go to the very top, and the difference is so minimal, but it does exist. So even a few players who never became world champion, like Vassily Ivanchuk, for instance, I think they belong to the same category.

Many politicians in the West cling to the notion of a partnership with Russia. They want to include [Vladimir] Putin, make compromises and constantly negotiate new deals with him. But history has taught us that the longer we pursue appeasement and do nothing, the higher the price will be later on. Dictators don't ask "Why?" before they seize even more power. They ask: "Why not?"

Chess continues to advance over time, so the players of the future will inevitably surpass me in the quality of their play, assuming the rules and regulations allow them to play serious chess. But it will likely be a long time before anyone spends 20 consecutive years as number, one as I did.
