Adolf Anderssen quotes:

Attack! Always Attack!

It is ... impossible to keep one's excellence in a little glass casket, like a jewel, to take it out whenever wanted. On the contrary, it can only be conserved by continuous and good practice.

I consider Mr. Morphy the finest chess player who ever existed. He is far superior to any now living, and would doubtless have beaten Labourdonnais himself. In all his games with me, he has not only played, in every instance, the exact move, but the most exact. He never makes a mistake; but, if his adversary commits the slightest error, he is lost.
