Some Stragegies in The Art of War of Sun Tzu

     Appear where they cannot go, head for where they least expect you. To travel hundreds of miles without fatigue,

go over land where there are no people.

    If you can keep the opponent's nation intact, then your own nation will also be intact. So this is the best.
    While giving the appearance of being far away, you step up your pace and get there before the opponent.
