With this mistake I deprived myself of the possibility to make a contribution to the treasury of chess art.

Though I would have liked my chances in a rematch in 1998 if I were better prepared, it was clear then that computer superiority over humans in chess had always been just a matter of time.

...comparing the capacity of computers to the capacity of the human brain, I've often wondered, where does our success come from? The answer is synthesis, the ability to combine creativity and calculation, art and science, into whole that is much greater than the sum of its parts.

Kortchnoi's heritage is many-faceted - over the decades he has several times corrected and changed his style. But the main thing has invariably remained his search for chess truth.

Vladimir Putin mainly has friends in Europe among the extreme right, such as Marine Le Pen's Front National in France.

Furthermore, a large portion of the assets of leading Russian figures is mixed, meaning that it is not quite clear how to counter this development.

Putin can't afford to leave the office because he will be in real danger of being prosecuted for things he and his people did during their stay in power.
