By positional play a master tries to prove and exploit true values, whereas by combinations he seeks to refute false values ... A combination produces an unexpected re-assessment of values.

Steinitz was a thinker worthy of a seat in the halls of a university. A player, as the world believed he was, he was not; his studious temperament made that impossible; and thus he was conquered by a player and in the end little valued by the world, he died.

Do not permit yourself to fall in love with the end-game play to the exclusion of entire games. It is well to have the whole story of how it happened; the complete play, not the denouement only. Do not embrace the rag-time and vaudeville of chess.

The hardest game to win is a won game

Of my fifty-seven years I have applied at least thirty to forgetting most of what I have learned or read. Since then, I have acquired a certain ease and cheer which I should never again like to be without. (...) I have stored little in my memory, but I can apply that little, and it is of use in many and varied emergencies. I keep it in order, but resist every attempt to increase its dead weight.

The attack is that process by means of which you remove obstructions.

I keep on fighting as long as my opponent can make a mistake.
