Solutions / August PAGE 13 / CHESS TO ENJOY THE USCF MISSION


USCF is a not-for-profit membership organization devoted to extend- ing the role of chess in American society. USCF promotes the study and knowledge of the game of chess, for its own sake as an art and enjoyment, but also as a means for the improvement of society. It informs, educates, and fosters the development of players (profes- sional and amateur) and potential players. It encourages the development of a network of institutions devoted to enhancing the growth of chess, from local clubs to state and regional associa- tions, and it promotes chess in American society. To these ends, USCF offers a monthly magazine, as well as targeted publications to its members and others. It supervises the organization of the U.S. Chess Championship, an open tournament held every summer, and other national events. It offers a wide range of books and services to its members and others at prices consistent with the benefits of its mem- bers. USCF serves as the governing body for chess in the United States and as a participant in international chess organizations and proj- ects. It is structured to ensure effective democratic procedures in accord with its bylaws and laws of the state of Illinois.
