Don't you know, there are some things that can beat smartness and foresight? Awkwardness and stupidity can. The best swordsman in the world doesn't need to fear the second best swordsman in the world; no, the person for him to be afraid of is some ignorant antagonist who has never had a sword in his hand before; he doesn't do the thing he ought to.
-Mark Twain, A Connecticut Yankee in King Arthur's Court (1889)

I've thought of similar ideas before, but the thing is that the expert will still win most of the time. Sure, even a blind squirrel finds a nut sometimes, and there's beginner's luck, but if your'e the best at something, no way will you lose to the worst.
