Yes, I have played a blitz game once. It was on a train, in 1929.

Chess is the art of analysis.

Chess is the art which expresses the science of logic.

Capablanca's phenomenal move-searching algorithm in those early years, when he possessed a wonderful ability for calculating variations very rapidly, made him invincible.

If Tal would learn to program himself properly, then it would become quite impossible to play against him.

Memorization of variations could be even worse than playing in a tournament without looking in the books at all.

Along with my retirement from chess analytical work seems to have gone too.
