On pleasant afternoons, I often go into Washington Square Park to watch the Master at work. The Master is a professional chess player—a chess hustler, if you will. He plays for fifty cents a game; if you win, you get the fifty, and if he wins, he gets it. In case of a draw, no money changes hands. The Master plays for at least eight hours a day, usually seven days a week; in the winter he plays indoors in one or another of the Village coffeehouses. It is a hard way to make a living, even if you win all your games; the Master wins most of his, although I have seen him get beaten several games straight. It is impossible to cheat in chess, and the only hustle that the Master perpetrates is to make his opponents think they are better than they are. When I saw him one day recently, he was at work on what in the language of the park is called a “potzer”—a relatively weak player with an inflated ego. A glance at the board showed that the Master was a rook and a pawn up on his adversary—a situation that would cause a rational man to resign the game at once. A potzer is not rational (otherwise, he would have avoided the contest in the first place), and this one was determined to fight it out to the end. He was moving pawns wildly, and his hands were beginning to tremble. Since there is no one to blame but yourself, nothing is more rankling than a defeat in chess, especially if you are under the illusion that you are better than your opponent.
