The Function of Strategy.
Herewith the rules and laws of the game are laid down; according to the very same rules play the beginner and the veteran, the duffer and the master. Whoever does not follow these rules does not play Chess; whoever follows them belongs to the community of Chess-players that counts many millions.
What distinguishes the Chess-players, all of whom follow the same rules, is called strategy: the plan, meaning, intent, force, briefly the reason of their moves.
This reason is no different from all reason, but a part of it, grown on its body, possessed of its force and conditioned by its pains. On the same tree where a little branch hangs, called the logic of Aristotle, there hangs another branch named Strategy in Chess.
