You can't overestimate the importance of psychology in chess, and as much as some players try to downplay it, I believe that winning requires a constant and strong psychology not just at the board but in every aspect of your life.

The technical phase can be boring because there is little opportunity for creavivity, for art. Boredom leads to complacency and mistakes.

Ironically, the main task of chess software companies today is to find ways to make the program weaker, not stronger, and to provide enough options that any user can pick from different levels and the machine will try to make enough mistakes to give him a chance.

Vladimir Putin is the bigger danger than Donald Trump because Trump can be dealt with within American democracy. There is an independent judiciary. He cannot overrule American courts. He will have to play by some rules. He will do damage certainly, but to do real damage I think he is too weak. Putin is aggressive wherever he can be. In Europe, in Germany, Putin will not stop.

By this measure (on the gap between Fischer & his contemporaries), I consider him the greatest world champion

Attackers may sometimes regret bad moves, but it is much worse to forever regret an opportunity you allowed to pass you by.

There are many facts showing that Putin's people enriched themselves by using power mechanisms so that's why for them losing power means losing their fortunes.
