Up to this point White has been following well-known analysis. But now he makes a fatal error: he begins to use his own head

When you don't know what to do, wait for your opponent to get an idea; it is sure to be bad.

All lines of play which lead to the imprisonment of the bishop are on principle to be condemned.

As Rousseau could not compose without his cat beside him, so I cannot play chess without my king's bishop. In its absense the game to me is lifeless and void. The vitalizing factor is missing, and I can devise no plan of attack.

... a lively imagination can exercise itself most fully and creatively in conjuring up magnificent combinations.

White lost because he failed to remember the right continuation and had to think up the moves himself

I have a quite feeling of pity for all those who don't know chess; almost like I am sorry for those who never learned to love. Chess, like love and music, has the ability of making people happy.
