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

Chess mastery essentially consists of analyzing Chess positions accurately

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

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.

If Tal sacrifices a piece, take it. If Petrosian sacrifices a piece, don't take it.

Chess is the art of analysis.
