Some part of a mistake is always correct

Tactics is knowing what to do when there is something to do. Strategy is knowing what to do when there is nothing to do.

It's always better to sacrifice your opponent's men

No one ever won a game by resigning.

The first essential for an attack is the will to attack.

Like the alchemist of old, for ever searching for the philosopher's stone, the analyst to-day never stops looking for stronger moves to prevent the defender from establishing equality.

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