Without error, there is no brilliancy.

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.

The laws of chess do not permit a free choice: you have to move whether you like it or not.

By what right does White, in an absolutely even position, such as after move one, when both sides have advanced 1. e4, sacrifice a pawn, whose recapture is quite uncertain, and open up his kingside to attack? And then follow up this policy by leaving the check of the black queen open? None whatever!

I have known many chess players, but among them there has been only one genius - Capablanca!

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

To refer to the oft mooted question, "Which piece is stronger, the Bishop or the Knight?" it is clear that the value of the Bishop undergoes greater changes than that of the Knight.
