Some part of a mistake is always correct

It is well-known that chess and music go well together, and many are those who have achieved unusual proficiency in both.

The winner is the one who makes the next-to-last mistake.

Psychologically, the choice of an appropriate opening is of the utmost importance for a player's success in a tournament.

In chess, there is only one mistake: over-estimation of your opponent. All else is either bad luck or weakness.

No one ever won a game by resigning.

A game is always won through a mistake.
